Description
Technical field
The utility model relates to the flexible glider of a kind of horizontal well test roller type, belongs to tester technical field.
Background technology
At present, the horizontal well tester method adopting of going into the well mainly contains two kinds: 1 uses crawl device to carry; 2 use coiled tubing to carry.And use the risk of crawl device test too large, and test time is very long under special circumstances, and instrument is probably buried in shaft bottom and is caused accident; Adopt coiled tubing testing cost too high.Therefore, need a kind of measuring technology of research application applicable and relatively simple, can make under pressure gauge to approaching horizontal segment, the true pressure of formation testing, temperature and formation parameter are also understood pit shaft hydrops situation, solve while testing the instrument difficult difficult problem of going into the well.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of horizontal well test roller type flexible glider.
The flexible glider of a kind of horizontal well test roller type, the first glider body, the flexible steel body of the second glider body for being formed by connecting by universal ball joint, the first vertical roller is connected with the first glider body by the first roller set bolt, and the combining structure of the first vertical roller and the first roller set bolt is distributed with more than 2 at the first glider body; The locked bolt of the first universal ball joint connects the first spherical rod member housing and the first glider body; One end of the first spherical rod member housing connects the first glider body, and the other end of the first glider body has interior connecting thread; The other end of the first spherical rod member housing connects one end of universal ball joint rod member, and the middle part of universal ball joint rod member connects universal ball joint adapter sleeve, and the other end of universal ball joint rod member connects the second glider body; One end of the second glider body connects the second spherical rod member housing, and the locked bolt of the second universal ball joint connects the second spherical rod member housing and the second glider body; The combining structure of the second vertical roller and the second roller set bolt is distributed with more than 2 at the second glider body; The other end of the second glider body has connecting bolt.
Advantage of the present utility model is novel in design, delicate structure.Glider body outer wall is provided with comprehensive vertical roller, can make the equipment of going into the well by better sliding and pass through inclination section under the effect of self gravitation.Between glider body, connecting what select is universal ball joint, and it has the features such as simple in structure, intensity is high, the diaxon angle of good endurance, connection is larger, just meets and is applicable to horizontal well and test the demand being flexible coupling of well tool at present.
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.
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, the flexible glider of a kind of horizontal well test roller type, 1, the flexible glider of a kind of horizontal well test roller type, it is characterized in that the first glider body 8, the flexible steel body of the second glider body 10 for being formed by connecting by universal ball joint, the first vertical roller 2 is connected with the first glider body 8 by the first roller set bolt 3, and the combining structure of the first vertical roller 2 and the first roller set bolt 3 is distributed with more than 2 at the first glider body 8;
The locked bolt 4 of the first universal ball joint connects the first spherical rod member housing 7 and the first glider body 8; The other end that one end of the first spherical rod member housing 7 connects the first glider body 8, the first glider bodies 8 has interior connecting thread 9; The other end of the first spherical rod member housing 7 connects one end of universal ball joint rod member 5, and the middle part of universal ball joint rod member 5 connects universal ball joint adapter sleeve 6, and the other end of universal ball joint rod member 5 connects the second glider body 10;
One end of the second glider body 10 connects the locked bolt 11 of the second spherical rod member housing 14, the second universal ball joint and connects the second spherical rod member housing 14 and the second glider body 10; The combining structure of the second vertical roller 13 and the second roller set bolt 12 is distributed with more than 2 at the second glider body 10; The other end of the second glider body 10 has connecting bolt 1.
During use, tester is connected to external screw thread place as electronic pressure gauge etc. is connected on the flexible glider of this roller type, lower connection internal thread place connects starting taper.By piano wire, plant and instrument below being entered to horizontal well tests, while approaching inclination section, glider contacts with tubing wall, under the effect of roller, the equipment of going into the well slides by self gravitation, and the flexibly connecting of universal ball joint makes device security by inclination section, enter horizontal segment smoothly and complete test assignment.
The invention of the flexible glider of horizontal well test roller type is used, can make downhole probe better slide and pass through inclination section by the effect of self gravitation, instrument reduced to a great extent in test process because cannot descend the situation of assigned position in pit shaft, the use of this instrument simultaneously, reduced the required counterweight of downhole probe, alleviated to a certain extent people's work workload and reduced potential safety hazard.Reduce the risk that instrument is met card, is hampered simultaneously, improving under the prerequisite of test success rate, reduced significantly cost.
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.
