CORE BARREL.
Application filed October 12, 1925. Serial No. 62,100.
The apparatus topbe described herein constitutes an improved core barrel or sand trap, and the material feature of the invention resides in the provision of means whereby pumping may continue during the time the core or sample of sand is being taken, thereby eliminating numerous disadvantages of the core barrels or sand traps previously known.
lt is well known, of course, that in the drilling of wells it is necessary from time to time to take a sample of the formation in which the drill is located. For this purpose a variety of core ,barrels or sand traps have been used; but in the operation of such it has been necessary to discontinue pumping while the core or sample was being taken. The taking of samples of the formation while the pumps are not running is subject to numerous disadvantages, a few of which `will be mentioned below.
The ordinary core barrel or sand trap is merely a shallow tube with cutters on the lower end thereof. Thisvis attached to the drill stem and rundown to the bottom of the well. The operator then drills into the formation with the core barrel the distance he wishes to take a core or sample. During the drilling with the core barrel the pumps are not running as the object is to allow some of the formation to `become packed in the barrel. In thus drilling with the pumps K oil' the sand often becomes burned. And again if the sand that the core is being taken of contains a great deal of gas the well may blow out. Another trouble that occurs is that in drilling with the pum s off the drill stem including the core barrel ecomes stuck; the walls of the well not holding up properly. Other troubles can occur, but the three I have mentioned are the most frequent and the most serious. The present valve mechanism is to be used in connection with the core barrel or sand trap. whereby pumping is permitted during the time the core or sample is being taken and thus eliminating the disadvantages of the core barrels or sand traps now in use.
A further object of the invention is to provide a valve mechanism which consists of few parts extremely simple in construction thereb reducing to a minimum the possibiity of t e apparatus getting out of order.
The construction and advantages thereof willbe fully understood by those skilled in the art from the following description when 2; whichbody is provided with ports 3 communicating with the 'interior ofthe valve body and with the well. Screw threadedly mounted on the lower end of the valve body 1s a cap 4 having a shoulder 5. A tubular member 6 is screw threadedly mounted in the ycap and is provided with a collar( cooperating witlrthe shoulder 5 of said cap..y
This `tubular member is also provided lwith a valve seat 8 at its upper end and has a passage 9 leading from the valve seat through the entire extent of the tubular member. A bushing 10 is screw threadedly or otherwise attached to the lower end of the tubular member and screw threadedly attached to the bushing is the ordinary core barrel 11 having the cutting teeth 12 at its lower end.
A valve 13 is slidably mounted in the valve body and has its lower end tapered to cooperate with the valve seat 8. The valve wall is provided with ports 14 normally permitting communication betweenthe interior of the valve and the interior of the core barrel through the passage 9. The upper end of the valve is provided with a. collar 15 normally resting on the shoulder 16 of the valve body; it being normally held inthis position by means of a coil spring 17 compressed between the shoulder 15 and the ring 18.
A packing ring, indicated b numeral 19, is mounted in the interior of te valve body below the ports 3 and is forced into packing' contact with the valve wall` by means of a screw threaded ring 20.
The operation of the device is as follows:
'\Vhen the device is run into the hole theV parts are in the position as indicated in Figure 1. During this operation the pumps are running and the water flows through the valve stem thence through the valve body into the valve, thence through the orts 14 of the valve to the passage 9 and t ence to the core barrel. After the device has been lowered the pumping is continued to clean ont the well. lVlien the well has been cleaned and the sample or core is to be taken the drill stem and valve body are rotated, thereby moving the cap 4 downwardly on the tubular member 6 to the position indicated in Figure 2. The upper end of the tubular member G and its valve seat 8 thus move upwardly in the valve body and after a short movement the valve seat engages the .valve 13 and thus cuts oil' the flow of water from the interior ot the valve to the passagev 9. As the tubular member moves further upward in the valve body it will raise the valve and bring the ports 14 ot' the valve into communication with the ports 3 of the valve body, thereby permitting the water to flow from the interior of the valve body to the well through the ports 141 and 3.
It is thus seen that the pumps are continually running; that when the well is being cleaned the water will flow directly through the valve body and the valve to the core barrel; and that when the drill stem is rotated the valve will be automatically closed, thereby shutting oil' the iow of water to the core barrel, and the ports 14 will be automatically brought into communication With the orts 3 thereby permitting the free fiow el) the liquid from the interior of the valve body to the well. As, hereinbefore mentioned, by permitting continuous pumping, the burning of the sample beine taken is revented; blow outs are prevented; and tie hole is kept walled up so as to prevent the drill stem or core barrel from becoming stuck. And it will be noted that the device is of such extreme simplicity that there are no parts which would get out of order in the ordinary operation of the apparatus.
In accordance with the patent statutes I have described what I now believe to bethe best embodiment of the invention, bilt I do not wish to be understood thereby as limiting myself orthe scope of the invention, as many changes and modifications may be made without departing from the spirit of the invention; all such I aim to include in the scope of the appended claims.
