Abstract
The invention discloses wellhead protecting mechanism, comprise collar (1), polylith junction steel plate (2), chuck (3) and polylith gusseted part (5), described polylith junction steel plate (2) two ends are respectively by being bolted 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 described chuck (3) 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).The present invention is by said structure, and wellhead assembly all gets a promotion in the tensile load and borehole pressure load of radial load, casing wt effect, makes this device not yielding, ensures passing through of downhole tool, improves field produces rate and economic benefit.
Description
Technical field
The present invention relates to drilling applications, be specifically related to wellhead protecting mechanism.
Background technology
In oil, gas drilling, usually install for controlling gas, liquid (oil, water etc.) fluid pressure and direction at well head, for suspension sleeve, oil pipe seal the device of oil pipe and sleeve pipe and each layer casing annulus.And mainly contain the radial load of blank step effect, the tensile load of casing wt effect and borehole pressure load for the load suffered by casing suspension device.Casing suspension device should be able to bear hung casing string weight, is just unlikely to produce necking down distortion and affect passing through of downhole tool.It is not in place that existing wellhead assembly does in the tensile load and borehole pressure load of radial load, casing wt effect, in use easily produces passing through of deformation effect downhole tool.For promoting that In Oil Field Exploration And Development is produced, well logging during, improve field produces rate and economic benefit, extremely urgent to the improvement of wellhead assembly.
Summary of the invention
Instant invention overcomes the deficiencies in the prior art; there is provided wellhead protecting mechanism, this wellhead assembly all gets a promotion in the tensile load and borehole pressure load of radial load, casing wt effect, makes this device not yielding; ensure 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 respectively by being bolted 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.Chuck arranges retaining ring control sleeve pipe approach axis, and retaining ring periphery arranges polylith gusseted plate and polylith junction steel plate supports fastening, compressive load in winding shaft.The collar arranged is that rigid material is made, and bottom utilizes junction steel plate to support, utilizes bolt to be connected between junction steel plate with collar, also can carry out to it radial load changing this device of guarantee after time junction steel plate uses one section.There is the gap of one fixed width between each junction steel plate, the tensile load of its weight effect can be improved, make this device not yielding, improve productivity ratio and the economic benefit in oil field.
Described chuck bottom even arranges multiple groove.Increase bottom friction.
Described retaining ring is clamped in the circular cylindrical cavity that polylith junction steel plate surrounds.Mutual restriction supports restriction mutually.
The upper surface of described chuck is also provided with multiple set bolt.Chuck can be fixedly secured.
The gap width formed between adjacent two junction steel plates is equal.
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 gets a promotion in the tensile load and borehole pressure load of radial load, casing wt effect, makes this device not yielding, ensures passing through of downhole tool, improves field produces rate and economic benefit.
2, multiple groove is set in the bottom of chuck, can bottom friction be increased, and junction steel plate wherein and being all connected and fixed by bolt between chuck and collar, when junction steel plate wearing and tearing also can be changed it, ensure 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.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further elaborated, and embodiments of the invention are not limited thereto.
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 even arranges multiple groove 7, and chuck 3 is octagon, the upper surface of chuck 3 is also provided with multiple set bolt 6.Polylith junction steel plate 2 two ends of the present embodiment are respectively by being bolted 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 the gap width formed between adjacent two junction steel plates 2 is equal.
Chuck arranges retaining ring control sleeve pipe approach axis, and retaining ring periphery arranges polylith gusseted plate and polylith junction steel plate supports fastening, compressive load in winding shaft.The collar arranged is that rigid material is made, and bottom utilizes junction steel plate to support, utilizes bolt to be connected between junction steel plate with collar, damages the radial load that also can carry out changing to it this device of guarantee after time junction steel plate uses one section.There is the gap of one fixed width between each junction steel plate, the tensile load of its weight effect can be improved, make this device not yielding, improve productivity ratio and the economic benefit in oil field.
Just this invention can be realized as mentioned above.
