Abstract
The invention discloses a well mouth protecting mechanism which comprises a top ring (1), a plurality of connecting steel plates (2), a chuck (3) and a plurality of triangular supporting pieces (5). The two ends of each connecting steel plate (2) are fixed between the top circle (1) and the chuck (3) through bolts. The connecting steel plates (2) are all simultaneously perpendicular to the top circle (1) and the chuck (3). A locking ring (4) is arranged at the center of the chuck (3). The outer wall of the locking ring (4) is uniformly fixed through the three triangular supporting pieces (5). The triangular supporting pieces (5) are all perpendicularly fixed to the upper surface of the chuck (3). Through the structure, the well mouth protecting mechanism is improved on the aspects of radial load, textile load of sleeve weight action and inter-well pressure load, the well mouth protecting mechanism does not easily deform and can ensure that underground tools can pass through a well mouth, and oil field yield and economic benefits are improved.
Description
Technical field
The present invention relates to drilling well field, be specifically related to wellhead protecting mechanism.
Background technology
In oil, gas drilling, conventionally at well head, install and to be used for controlling gas, liquid (oil, water etc.) fluid pressure and direction, for suspension sleeve, oil pipe and seal oil pipe and the device of sleeve pipe and each layer of sleeve pipe annular space.And mainly contain the radial load of blank step effect, the tensile load of casing wt effect and borehole pressure load for the suffered load of casing suspension device.Casing suspension device should be able to bear hung casing string weight, is just unlikely to produce necking down distortion and affects passing through of downhole tool.Existing wellhead assembly is not in place what do aspect the tensile load of radial load, casing wt effect and borehole pressure load, in use easily produces passing through of deformation effect downhole tool.For promoting In Oil Field Exploration And Development to produce, well logging during, improves field produces rate and economic benefit, extremely urgent to the improvement of wellhead assembly.
Summary of the invention
The present invention has overcome the deficiencies in the prior art; wellhead protecting mechanism is provided, and this wellhead assembly, all getting a promotion aspect the tensile load of radial load, casing wt effect and borehole pressure load, makes this device not yielding; guarantee passing through of downhole tool, improve field produces rate and economic benefit.
For solving above-mentioned technical problem, the present invention is by the following technical solutions: wellhead protecting mechanism, comprise collar, polylith junction steel plate, chuck and polylith gusseted part, described polylith junction steel plate two ends are bolted on respectively between collar and chuck, and polylith junction steel plate is all simultaneously perpendicular to collar and chuck; The center of described chuck is provided with retaining ring, and the outer wall of retaining ring adopts polylith gusseted part evenly to fix, and polylith gusseted part is all vertically fixed on the upper surface of chuck.Retaining ring is set on chuck sleeve pipe approach axis is controlled, and retaining ring periphery arrange polylith gusseted plate and polylith junction steel plate support fastening, winding shaft internal pressure load.The collar arranging is that rigid material is made, and bottom utilizes junction steel plate to support, and between junction steel plate and collar, utilizes bolt to be connected, and also can change to it radial load of this device of assurance after when junction steel plate is used one section.Between each junction steel plate, there is the gap of certain width, can improve the tensile load of its weight effect, make this device not yielding, improve productivity ratio and the economic benefit in oil field.
Described chuck bottom even arranges a plurality of grooves.Increase bottom friction.
Described retaining ring is clamped in the circular cylindrical cavity that polylith junction steel plate surrounds.Restriction is supported in restriction mutually mutually.
On the upper surface of described chuck, be also provided with a plurality of set bolts.Chuck can be fixedly secured.
Between adjacent two junction steel plates, formed gap width equates.
Described chuck is octagon.
Compared with prior art, the invention has the beneficial effects as follows:
1, the present invention adopts this structure, and wellhead assembly, all getting a promotion aspect the tensile load of radial load, casing wt effect and borehole pressure load, makes this device not yielding, guarantees passing through of downhole tool, improves field produces rate and economic benefit.
2, in the bottom of chuck, a plurality of grooves are set, can increase bottom friction, and all by bolt, be connected and fixed between junction steel plate wherein and chuck and collar, when junction steel plate wearing and tearing, also can change it, guarantee its bearing capacity.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure, Reference numeral is expressed as: 1, collar; 2, junction steel plate; 3, chuck; 4, retaining ring; 5, gusseted part; 6, set bolt; 7, groove.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is further elaborated, and embodiments of the invention are not limited to this.
Embodiment:
As shown in Figure 1, the present invention includes collar 1, polylith junction steel plate 2, chuck 3 and polylith gusseted part 5, chuck 3 bottom evens arrange a plurality of grooves 7, and chuck 3 is octagon, is also provided with a plurality of set bolts 6 on the upper surface of chuck 3.Polylith junction steel plate 2 two ends of the present embodiment are bolted on respectively between collar 1 and chuck 3, and polylith junction steel plate 2 is all simultaneously perpendicular to collar 1 and chuck 3.The center of the chuck 3 of the present embodiment is provided with retaining ring 4, and the outer wall of retaining ring 4 adopts polylith gusseted part 5 evenly to fix, and polylith gusseted part 5 is all vertically fixed on the upper surface of chuck 3.Retaining ring 4 is wherein clamped in the circular cylindrical cavity that polylith junction steel plate 2 surrounds, and between adjacent two junction steel plates 2, formed gap width equates.
Retaining ring is set on chuck sleeve pipe approach axis is controlled, and retaining ring periphery arrange polylith gusseted plate and polylith junction steel plate support fastening, winding shaft internal pressure load.The collar arranging is that rigid material is made, and bottom utilizes junction steel plate to support, and between junction steel plate and collar, utilizes bolt to be connected, and also damages after when junction steel plate is used one section and can change to it radial load of this device of assurance.Between each junction steel plate, there is the gap of certain width, can improve the tensile load of its weight effect, make this device not yielding, improve productivity ratio and the economic benefit in oil field.
Just can realize this invention as mentioned above.
