Abstract
The utility model relates to a dropping-proof device for testing an oil/water well on the oilfield. The utility model is mainly composed of a main body, a hollow cylindrical pipe, a control rod and other parts. The utility model is characterized in that the hollow cylindrical pipe can be rotated for definite angle along a shaft in the main body in order to prevent a test tool or an instrument moving downward. Thus, the test tool or the instrument can not fall into the well, and the dropping-proof device can prevent accidents occurring, promoting the regular production of oil wells and water wells, and also reducing the labor intensity of well testing workers. The user doesn't need to close two thirds of a paraffin removal gate, pull a steel wire, detect a shutter, etc. The utility model can improve the work efficiency.
Description
The utility model relates to the wellhead assembly that plays anti-lost effect in oil field oil, the well well testing operation process.
During oil field oil, well well testing operation now, downhole testing instrument or instrument and lubricator plug often take place to collide in reason such as malfunctioning or operating personnel's negligence owing to the winch tachometer, cause testing tool or instrument to fall into accident in the well.Make oil, well can not ordinary production.
In view of the above problems, regulation the utility model task is design and makes a kind of and prevent from not terminate in after testing tool or instrument and the collision of lubricator plug and fall in the well, prevents the accident generation.
The utility model is achieved in that " a kind of oil, well well testing dropping against device; it is characterized in that being provided with mobilizable hollow, cylindrical tube in the inside of dropping against device main body; and can rotate along axle; axle is installed in the bottom hole of main body; pass through in order to control testing tool or instrument, control lever rise and overcome spring force and can make hollow, cylindrical tube push the center in certain angular range.
Below in conjunction with accompanying drawing structure of the present utility model and effect are further specified,
Figure one is a front view of the present utility model.
Figure two is A-A sectional drawings of the present utility model.
Figure three is B-B sectional drawings of the present utility model.
With reference to accompanying drawing: the lower end of main body (2) is with the flange of the oil that is threaded, well paraffin valve.Lower lumen in main body (2) is provided with platform, and a side is provided with a vertical slot, is drilled with a hole in the groove, and an end in hole is threaded, with screw (7) fit sealing.The groove mesopore that the lower end bossing of hollow, cylindrical tube (3) is drilled with a hole and main body (2) matches, and in axle (6) patchhole, hollow, cylindrical tube (3) can be rotated in the certain angle scope along axle (6), passes through in order to stop testing tool or instrument.Be provided with a threaded hole on the top of main body (2), the upper end of hollow, cylindrical tube (3) is provided with a blind hole, it is fastening that spring (4) inserts back screw (5), so hollow, cylindrical tube (3) first termination portion under the thrust of spring (4) is in channel center always.A side is provided with a vertical slot ditch at the middle part of hollow, cylindrical tube (3).Hollow, cylindrical tube (3) can be pushed to the centre by the control lever that valve seat (9), sealing ring (10), valve gap (11), pressure cap (12), handwheel (13), nut (14), control lever (8) are formed, testing tool or instrument are gone into the well.Top connection (1) is threaded on the main body (2).
This oil, well well testing are installed on the flange of paraffin valve with dropping against device.On take over control jet pipe.Control lever (8) is regained, when testing tool or instrument when the down-hole trips out, can pass through dropping against device smoothly, the leading cadre that returns immediately under the effect of spring (4) of hollow, cylindrical tube (3) is descending with prevention testing tool or instrument then.
When testing tool or instrument begin to go into the well if rotation control lever (8) but just in the lower going-into-well.
This oil, water well test can prevent not only that with dropping against device testing tool or instrument from falling in the well, and can reduce the well testing workman and close 2/3 paraffin valve, draw steel wire to visit work such as flashboard, make easy to operately, increase work efficiency.
Claims (4)
1, a kind of oil field oil, well well testing dropping against device mainly partly wait part to form by main body (2), hollow, cylindrical tube (3), axle (6), spring (4), joint (1) and control lever; The inside that it is characterized in that main body (2) is provided with mobilizable hollow, cylindrical tube (3), and can in certain angular range, rotate along axle, descending in order to stop testing tool, control lever (8) can be controlled hollow, cylindrical tube (3) angle of inclination, makes in the smooth lower going-into-well of testing tool.
2, oil according to claim 1, well well testing dropping against device, the lower lumen that it is characterized in that main body (2) be provided with platform one side have one and the Kong Bingyi end that matches of axle (6) be threaded, the middle part is provided with for the screwed hole of control lever (8) by dress, and the upper end is provided with a screwed hole by shock mount (4).
3, oil according to claim 1, well well testing dropping against device is characterized in that bottom one side of hollow, cylindrical tube (3) is provided with boss, and through hole are arranged.The head that middle part one side is provided with a groove and control lever (8) matches; Upper end one side is provided with a blind hole, and head one side is thicker.
4, oil according to claim 1, well well testing dropping against device is characterized in that the control lever part is made up of control lever (8), valve seat (9), valve gap (11), pressure cap (12), handwheel (13), nut (14).
