Abstract
The invention discloses a special tool for deep water test depth correction. The tool comprises an upper airtight buckle used to connect a pup joint upper pipe string, an upper pup joint body, an integrated lifting lug, a lower thickened pup joint body, and a lower airtight buckle used to connect a pup joint lower pipe string. The upper pup joint body and the lower thickened pup joint body are of an integrated structure. The integrated lifting lug sleeves the upper pup joint body and is locked by a jackscrew. By adopting the structure, under deep-water sea conditions, a depth correction cable can be fixed to a test pipe string so as to lift and sink with the test pipe string during conventional semi-submersible platform deepwater test pipe string depth correction. Therefore, large error caused by test pipe string depth correction data is avoided, the safety of the test pipe string is ensured, and the risk and the occurrence of accidents are reduced. In addition, the tool has the advantages of simple operation, convenient maintenance, and the like.
Description
Technical field
The present invention relates to deep water testing tool technical field, particularly relate to the dark special tool in a kind of deep water test school.
Background technology
When conventional semisubmersible platform test string school is dark, be hang in the wear-resistant bushing of underwater well head by being sat by tubing string, well head compensates by drawing the heave compensation that rope realizes tubing string; And deep water is tested, when tubing string school is dark, the wear-resistant bushing of well head cannot be seated at because tubing string more than mud face is too heavy, need to carry out school in the state of tourist bus upper lifting pipe post dark, cause and conventional compensation rope cannot be used to carry out the heave compensation of tubing string, overhead traveling crane, lower sheave group can not realize geo-stationary, therefore cannot confirm the accuracy of the dark data in school.Two kinds of practices are had in the world: one is that the well head that adopts sits slips more, and take the average of the dark data in repeatedly school to choose the degree of depth, if the method is when platform heave is larger, the depth error brought is very large to this problem; Two is adopt the display that is hampered of plug-in type test string as mark, carry out tubing string join length by now printing the tubing string degree of depth, if display is inaccurate but the method insertion sealing is hampered, or during the tubing string compression situation such as excessive, the tubing string error brought is also very large, and also brings potential risks to tubing string safety.The dark error in school brought of above two kinds of modes is all very large, therefore when meeting the dark error in high-level school, needing to research and develop the dark special tool in a kind of deep water test string well head school, solving the problem that the dark error in deep water test string school is larger.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the invention provides the dark special tool in a kind of deep water test school, under deep water sea conditions, when conventional semisubmersible platform deep water test string school is dark, the dark cable in school can be fixed on heave together on test string, avoid the comparatively big error that the dark data in test string school cause, and ensure test string safety, reduce risks and the generation of accident.
The technical solution adopted in the present invention is: the dark special tool in a kind of deep water test school, comprise the upper airtight button of tubing string on connecting short section, top sub body, monolithic hanger, bottom thickening pipe nipple body and the lower airtight button for connecting short section lower tubular column, described top sub body and bottom thickening pipe nipple body are integral type structure, and monolithic hanger to be set on top sub body and to be locked by jackscrew.
As the preferred technical scheme of one of the present invention, described top sub body is identical with the internal diameter of bottom thickening pipe nipple body, and the external diameter of bottom thickening pipe nipple body is greater than the external diameter of top sub body.
As the preferred technical scheme of one of the present invention, the otic placode of described monolithic hanger is provided with the fixing hole for the dark cable in fixing school.
Compared with prior art, the invention has the beneficial effects as follows: owing to have employed above-mentioned structure, the present invention is under deep water sea conditions, when conventional semisubmersible platform deep water test string school is dark, the dark cable in school can be fixed on heave together on test string, avoid the comparatively big error that the dark data in test string school cause, and ensure test string safety, reduce risks and the generation of accident.In addition, the present invention also has the advantages such as simple to operate and easy maintenance.

Detailed description of the invention
In order to more clearly understand technical scheme of the present invention, below in conjunction with accompanying drawing, the present invention is further described.
Embodiment one
As shown in Figure 1, the dark special tool in a kind of deep water test school described in the present embodiment, comprise the upper airtight button 1 of tubing string on connecting short section, top sub body 2, monolithic hanger 3, bottom thickening pipe nipple body 4 and the lower airtight button 5 for connecting short section lower tubular column, described top sub body 2 and bottom thickening pipe nipple body 4 are integral type structure, monolithic hanger 3 to be set on top sub body 2 and to be locked by jackscrew 6, upper airtight button 1 and lower airtight button 5, for the tubing string that connecting short section is upper and lower, and play sealing function.
Wherein, in the present embodiment, described top sub body 2 is identical with the internal diameter of bottom thickening pipe nipple body 4, the external diameter of bottom thickening pipe nipple body 4 is greater than the external diameter of top sub body 2, top sub body 2 and bottom thickening pipe nipple body 4, as the passage of transferring monolithic hanger 3, and support and fixing monolithic hanger 3.
Wherein, in the present embodiment, the otic placode of described monolithic hanger 3 is provided with the fixing hole 7 for the dark cable in fixing school, and monolithic hanger 3 is as the standing part connecting the dark cable in school, and it is sleeve Integral keeper, internal diameter is consistent with top sub body 2 external diameter, down overlap into from top sub body 2 top, can realize rotating to each circumference, use jackscrew 6 to be fixed in nipple body, the dark cable in school can be fixed on hanger, ensures the dark cable in school and nipple body geo-stationary.
During use, upper airtight button 1 and lower airtight button 5 are airtight buttons, first with upper and lower tubing string be connected and on be anchored to nominal torque, monolithic hanger 3 is lowered through top sub body 2, support and be fixed on bottom thickening pipe nipple body 4, the dark cable in school is fixed on hanger, can ensure the dark cable in school and nipple body geo-stationary.
Set forth a lot of detail in description above so that fully understand the present invention, but the present invention can also adopt other to be different from other modes described here and implement, and therefore, can not be interpreted as limiting the scope of the invention.
