Description
Technical field
The utility model relates to the rig tool used in a kind of oilfield, is a kind of Multi-position rotation eccentric testing wellhead assembly being specifically designed to oil well on-line testing.
Background technology
In field produces, in order to understand the down-hole technical data in oil well production process, oil recovery factory adopts eccentric testing well head to realize the wellhead assembly of on-line testing of not stopping production usually, although substantially reach instructions for use through use for many years.But also often can there is tester after testing is complete and can not propose the phenomenon of well head smoothly, test data is caused not take out in time, its reason is that the steel wire of connecting test instrument is wrapped on oil pipe when going into the well, and when above carrying, steel wire is tied tight oil pipe and instrument can not be taken out.
Because above-mentioned defect, the design people, actively in addition research and innovation, to founding a kind of Multi-position rotation eccentric testing wellhead assembly, make it have more value in industry.
Utility model content
For solving the problems of the technologies described above, the purpose of this utility model is to provide a kind of test steel wire coiled tubing that can solve makes instrument can not take out the Multi-position rotation eccentric testing wellhead assembly of problem.
Multi-position rotation eccentric testing wellhead assembly of the present utility model, comprise central tube, minor diameter tubing, main body, second rotary body and the 3rd rotary body, top the 3rd rotary body upper bearing of described 3rd rotary body is fixed in main body, bottom the 3rd rotary body thrust bearing of described 3rd rotary body is fixed in main body, described second rotary body is arranged on the 3rd rotary body through bearing, the top of described central tube is fixed on the second rotary body through central tube nut, the bottom second rotary body lower thrust bearing of described central tube is connected with the second rotary body, sheathed upper press cover on described second rotary body, described upper press cover is fixed through upper press cover set bolt and main body, described minor diameter tubing is threaded with described second rotary body.
Further, described central tube top is provided with top connection.
Further, described upper press cover set bolt is set to hex bolts.
Further, lower body part establishes main flange, described main flange through well head bolt and wellhead flange fastening, seal with ring gasket between described main flange and described wellhead flange.
By such scheme, the utility model at least has the following advantages: described Multi-position rotation eccentric testing wellhead assembly improves on the basis of existing decentralized wellhead, design by Multi-position rotation, crack scheme for tester proposes to provide three kinds smoothly, solve the phenomenon of tester Ka Jing preferably.Specific as follows:
1, minor diameter tubing is rotated.Be applicable to the straight well that gradient is less; Minor diameter tubing is motionless, and eccentric minor diameter test port rotates.The method is applicable to the larger straight well of gradient;
2, when minor diameter tubing turns motionless, rotary test mouth breaks strength;
3, minor diameter tubing rotates together with eccentric testing mouth.Be applicable to the larger directional well of gradient or horizontal well, when above-mentioned two kinds of methods all bad used time, integral-rotation minor diameter tubing and test port, thus reach the contradiction cracking steel wire winding oil pipe.
Above-mentioned explanation is only the general introduction of technical solutions of the utility model, in order to better understand technological means of the present utility model, and can be implemented according to the content of manual, coordinates accompanying drawing to be described in detail as follows below with preferred embodiment of the present utility model.
