Abstract
An auxiliary tool for jacking a casing belongs to the technical field of reinforcing of wellhead casings of oil field production wells. The left side and the right side of semicircle ring cylinder are connected with the flat board respectively, and there is the bow-shaped groove flat board one side, and dull and stereotyped one end has outer recess, and the corner of outer recess is 45, and there are first bolt hole and second bolt hole in the left side of semicircle ring cylinder, and the right side of semicircle ring cylinder has the bolt hole of symmetry with first bolt hole and second bolt hole. The utility model discloses can be firm block the sleeve pipe body, prevent to take place relative displacement and slippage between jacking in-process instrument and the oil reservoir sleeve pipe. The arch-shaped groove is rectangular, the width of the bottom surface of the arch-shaped groove is consistent with the outer diameter of the bottom flange, and the problem of stress fracture of a right-angle surface in the arch-shaped groove in the jacking process can be prevented.
Description
Technical field
The utility model relates to a kind of aid of jacking sleeve pipe, belongs to oilfield producing well wellhead casing pipe reinforcing technique field.
Background technology
Due to shallow-layer water source transition exploitation, cause the sedimentation of caving in of a large amount of regional earth's surfaces, to people's life, bring and have a strong impact on.And in oilfield development process, owing to being subject to the impact of ground settlement, there is the problem of altering on production string in various degree in part producing well, height is not from several centimeters to tens centimeters etc., the doughnut-shaped steel plate of well head packing table cover and oil sets annular space misplaces, and What is more well head surface pipe and production procedure drawing crack or break; Meanwhile, along with moving up and down of rod-pumped well, well head production string moves reciprocatingly up and down with oil pumper, and the easy like this sleeve pipe that causes is tired, and sleeve pipe fatigue fracture occurs, and brings to the normal exploitation in oil field and has a strong impact on.
Administer on sleeve pipe and alter and become an instant problem in oilfield development process.In this year, aspect altering, there is multiple multi-form administration way on improvement sleeve pipe.Such as the production string of altering on slicing off, administration way in cannula tip again thread making, this method adopts and directly reduces production string height, utilize the conventional doughnut-shaped steel plate using to retighten and packing table cover and oil sets annular space, and after the thread making of oil jacket top, can directly connect well head production tree, follow-up oil well operation construction is not impacted., the good results are evident in the situation of administering >20 centimetre for this type of technique, and economic benefit is also relatively suitable; This kind of technique of situation for <20 centimetre is not just so obvious from economic benefit angle.Administer in the past Similar Problems, also taked the fixing means of directly welding and angle iron welding, but it is large because rising, to determine power, occur the problem of Rewelding, and Rewelding also easily produces damage to sleeve pipe, so all there is no for a long time good solution.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of aid of jacking sleeve pipe.
A kind of aid of jacking sleeve pipe, the left side of semicircular ring cylinder and right side are connected with respectively flat board, a dull and stereotyped side has arcuate slots, there is outer groove dull and stereotyped one end, the corner of outer groove is 45 °, there are the first bolt hole and the second bolt hole in the left side of semicircular ring cylinder, and there is the bolt hole with the first bolt hole and the second bolt hole symmetry on the right side of semicircular ring cylinder.
Advantage of the present utility model symmetrical arc axis tile when jacking sleeve pipe can firmly block sleeve body, prevents between instrument and production string, relative displacement occurring and slippage in jacking process.Arcuate slots is rectangle, and its bottom width and end flange outer diameter are in the same size, can prevent that in arcuate slots, the problem of stress fracture appears in right angle face in jacking process.Turning is 45 ° in body two ear end faces, can effectively prevent that the problem of stress fracture from appearring in two ear end faces in jacking process.Arc axis tile can improve the safety of sleeve pipe jacking reinforcing process, guarantees operating personnel's safety.Simple in structure, with low cost, installation and easy to operate.Can allow safe, quick that sleeve pipe jacking strengthening construction becomes, guarantee to alter on sleeve pipe completing smoothly of improvement.
Accompanying drawing explanation
When considered in conjunction with the accompanying drawings, by the detailed description with reference to below, can more completely understand better the utility model and easily learn wherein many advantages of following, but accompanying drawing described herein is used to provide further understanding of the present utility model, form a part of the present utility model, schematic description and description of the present utility model is used for explaining the utility model, do not form improper restriction of the present utility model, as schemed wherein:
Fig. 1 is structural representation of the present utility model.
Fig. 2 is structure schematic top plan view of the present utility model.
Below in conjunction with drawings and Examples, the utility model is further illustrated.
The specific embodiment
Obviously, the many modifications and variations that those skilled in the art do based on aim of the present utility model belong to protection domain of the present utility model.
Embodiment 1: as shown in Figure 1 and Figure 2, a kind of aid of jacking sleeve pipe, the left side of semicircular ring cylinder 1 and right side are connected with respectively flat board, a dull and stereotyped side has arcuate slots 4, there is outer groove dull and stereotyped one end, the corner 3 of outer groove is 45 °, and there are the first bolt hole 2 and the second bolt hole 5 in the left side of semicircular ring cylinder 1, and there are the 3rd bolt hole and the 4th bolt hole in the right side of semicircular ring cylinder 1.
An aid for jacking sleeve pipe is in use jointly to complete by a secondary symmetrical arc axis tile.Semicircular ring cylinder 1 inner surface at body middle part overlaps with this contact level of production string.The bottom width of arcuate slots 4 is consistent with flange outer diameter at the bottom of well head.In the end face on left side and right side, corner 3 is 45 °.
By being stuck on wellhead casing pipe rising pipe nipple of semicircular ring cylinder 1 symmetry of arc axis tile, and at the bottom of production tree, flange is stuck in arcuate slots 4, in four bolts hole of body symmetry, four bolts is installed and is screwed, and guarantees that the arc axis tile of symmetry is tightly embraced rising pipe nipple.
As mentioned above, embodiment of the present utility model is explained, but as long as not departing from fact inventive point of the present utility model and effect can have a lot of distortion, this will be readily apparent to persons skilled in the art.Therefore, within such variation is also all included in protection domain of the present utility model.
