7 Claims. (Cl. 103-203) This invention relates to the production of oil from wells and more particularly to the prevention of the depositing of paraffin or the like in well tubing during the removal of oil from a well.
During the operation of oil wells, one difliculty which is frequently encountered is the gradual depositing from the oil as the same flows through the well tubing of paraffin or other constituents having similar properties, such deposits often accumulating to an extent to prevent further removal of the oil and making it necessary to carry out expensive reconditioning operations before production can be resumed. It has been determined that one of the chief causes of the formation of such deposits in well tubing is the cooling effect of gas in the oil due to the reduction in pressure which occurs as the oil flows upwardly, the gas expanding as the pressure is reduced and causing areduction in the temperature of the oil suflicient to effect congealing of the paraffin. Thus when the vapor pressure of dissolved gaseous hydrocarbons inthe fluid in the bottom of the well exceeds the hydrostatic head of the column of fluid in the well tubing, gas is liberated and the expansion of the gas causes cooling of the oil which results in the formation of paraffin deposits in the tubing.
In wells which are being operated by pumping, the reduction in pressure as the oil moves upwardly also results in the separation of the gas from the liquid which sometimes causes the accumulation of gas in the working barrel of the pump in the space between the standing valve and the traveling valve, so that a gas lock is formed which prevents the pumping of the oil.
The present invention has for its chief object the provision of means for causing the separation of gas from the oil at a point in the well such that the depositing of paraflin in the well tubing will be prevented.
Another object of the invention is to provide means for causing the separation of gas from the oil in a well in a location to prevent such gas from interfering with the pumping of the oil from the well.
A further object of the invention is the provision of a gas separator for oil wells which operates to separate gas from the oil in a location to cause the gas to be retained in contact with oil flowing into the well from the surrounding formation while permitting the separated oil to enter the well tubing.
Another object of the invention is to provide gas separating mechanism for use in conjunction with well tubing and which embodies means for closing the tubing against the upward flow of fluid therethrough when the supply of oil in the well falls below a predetermined level and for opening the tubing to such flow when the supply of oil rises above said level.
Another object of the invention is the provision of a flow controlling gas separator assembly for use on well tubing which operates to cause separation of gas from the oil in the well before the oil enters the tubing and which also functions to close the tubing against the upward flow of gas therethroughwhen the level of-oil in the well falls to a point at which gas may enter the tubing.
A further object of the invention is the provision of gas separating mechanism for use in oil wells which embodies an outer tubular housing having a closed bottom and whose upper end is opened positioned in surround-' ing radially spaced relation to the lower end portion of a Well tubing, and an inner tubular member or bucket movably disposed in the housing in radially'inwardly spaced relation to the housing and in surrounding radially outwardly spaced relation to the well tubing, said bucket being positioned to permit the flow of fluid in the housing into the bucket when the fluid in the housing rises above a predetermined level to cause the bucket to move downwardly to a position to open the lower end of the tubing, andto be moved upwardly by buoyancy when the fluid in the bucket falls to a predetermined level therein to a position to close the tubing against upward flow of fluid therethrough.
Other important objects and advantages of the invention will be made apparent from the following detailed description, constituting a specification of the same, when considered in conjunction with the annexed drawings, wherein-- Figure l is a fragmentary side elevational view, partly in cross-section and on a reduced scale of an oil well illustrating the invention as used in conjunction with well pumping apparatus,
Figure 2 is a vertical, central, cross-sectional View of the invention, showing the same in condition to close the tubing against upward flow of gas therethrough,
Figure 3 is a view similar to that of Figure 2, showing I the invention in condition to permit the upward flow of fluid through the tubing;
Figure 4 is a cross-sectional view, taken along the line 44 of Figure 3, looking in the direction indicated by the arrowsj and,
Figure 5 is a cross-sectional view taken along the line 5--5 of Figure 2.
Referring now to the drawings in greater detail, the invention is illustrated in connection with a well pump having a working barrel 10, which may form a part of a tubing string of the usual type positioned in a well which is also provided with the usual casing 12. Within the working barrel a pump plunger 14 is provided which is connected to the lower end of a pump rod 16 and which carries a traveling valve 18 of the usual type, and beneath the plunger the barrel is provided with a standing valve 20.
The oil and gas separator of the invention is connected in communication with the lower end of the working barrel 10 and includes an inner tubular member 22 adapted to be connected at its upper end to the lower end of the working barrel 10 and whose lower end portion is tapered to form a portion 24 of reduced diameter which is internally threaded for the connection thereto of a pipe 26. An outer housing or bucket 28 surrounds the lower end portion of the member 22 and pipe 26 in radially outwardly spaced relation thereto and is connected to the member 22 by radial arms 30 welded to the member and housing.
The upper end of the housing 28 .is open, and at its lower end the housing is closed by a bottom 28a, which may be provided with a screw plug 32, which may be removed for cleaning purposes. Within the housing the member 22 is provided with an external annular flange or fin 34, whose outer edge is spaced radially inwardly from the interior of the housing, at a location somewhat end face 36 for a purpose to be hereinafter explained.
Within the housing 28 a tubular element'or inner- Patented Oct. 22, 1957 3 bucket 38" is movably positioned, in radially outwardly spaced relation to the pipe 26, and in inwardly radially spaced relation to the interior of the housing 28. The
bottom 28d of the housing, with which the element is engageable, to limit downward movement of' the element in the housing.
A valve member 46,.01'1' ball shape, is positioned within the element 38, and attached centrally to the, bottom 38a of the element, in position to engage the beveled end face 36 of the pipe 26, when the element 38. reaches the limit of its upward movement in the housing, to close the pipe 26.
,The dimensions of the parts. are such that when the valve member 46 is in closing contact with the beveled end face 36 the upper open end of the element 38 will be spaced downwardly from the exterior flange 34 on the inner tubular member 22, so that fluid may at all times overflow from the interior of the housing into the element 38 In making use of the invention constructed as described above, the tubular member 22 is connected at its upper end to the lower end of theworking barrel 10, or to the lower end of a tubing string, when other means is used for removing oil from the well, and the apparatus is positioned in a well in the manner illustrated in Figure 1. With the apparatus so positioned in the well, well fluid from the surrounding formation may flow into the upper end of the outer housing 28 to fill the housing, and when the fluid in the housing rises to a level to overflow into the inner bucket 38, the inner bucket will be filled with fluid thereby decreasing or reducing its buoyancy in the well fluid, whereupon the inner bucket will move downwardly to the position shown in Figure 3, to open the lower end of the pipe 26, so that fluid may be pumped upwardly through the tubing string.
During the flow of oil from the well into the upper end of the housing 28 the flow of oil will be retarded by the battle 34, which causes the oil to be agitated, resulting in separation of gas from the oil, such gas then passing upwardly out of the open end of the housing back into the well.
Should the level of the oil in the well fall below the upper end of the housing 28, then further removal of the oil from the inner bucket 38 will increase its buoy: ancy so as to cause the inner bucket to float upwardly in the housing until the valve member 46 is moved into closing contact with the beveled end face 36 of the pipe 26, to close the pipe, thus preventing the entrance of gas from the well into the tubing string. As soon as oil from the formation has accumulated in the well to an extent to permit the flow of oil into the upper end of the housing 28, oil in the housing will overflow into the inner bucket, to again cause the inner bucket to move downwardly to open the lower end of the pipe 26, and removal of oil from'the well can then be resumed.
It will thus be seen that the invention provides an oil and gas separator of simple design and rugged construction, by which gas may be caused' to separate from the oilat a location to prevent the depositing of parafiin in the well tubing, and which also operates to assure the retention of the gas in the well whereby the pressure in the well. may be maintained, but which operates automatically to permit the removal of oil from the well as long as the level of oil in the well is above a predetermined level.
To assure eflfective operation of the device from its initial installation in the" well, both the inner and outer buckets, at the time the device is lowered into the well on the tubing string, may be initially filled with a relatively high specific gravity liquid, such as salt water or brine like that commonly produced from oil wells. The valve at the end of the tubing string will then be in the open position shown in Figure 3. A few strokes of the pump will ordinarily be suflicient thereafter to suck the liquid from the outer bucket down to the level of the top of the inner bucket, which will thereby provide a minimum level. of relatively heavy liquid in the outer bucket at all times. The inner bucket may be suitably weighted relative to thelspecific gravity of the heavy liquid, so that introduction of predetermined quantities of oil will cause the inner bucket to sink and open the valve, thereby providing sensitivity for the device.
Each of the buckets, but more particularly the inner bucket, is preferably constructed of any suitable non magnetic material, which may be metallic, such as copper, brass, aluminum and the like, or non-metallic material such as an appropriate, and known plastic material, in order thereby to obviate magneto-static attraction which, if both buckets were constructed of iron or steel, can occur between the buckets as a result of the relative movement of the inner bucket, and] thereby undesir ably hinder the necessary free movement of the inner bucket.
The invention has been, disclosed herein in connection with a certain specific embodiment of the same, but it will be understood that this is intended by way of example only, and that numerous changes can be made in the construction and arrangement of the various parts within the spirit of the invention, and the scope of the appended claims.
