Abstract
A falling-prevention plug relates to a testing plug for an oil-water well, which comprises a body (6). A rotary square (1) is arranged on the rear part of the body (6), a pressure spring (3) is fixed at the bottom of the hollow cavity on the front part of the body (6), a pressure pad (4) is tightly attached to the pressure spring (3), the bottom of a bolt (5) is tightly attached to the pressure pad (4), and the outer side face of the head of the bolt (5) is a conical surface which is closely attached to a cone formed by the reduction of the inner side of the opening of the hollow cavity on the front part of the body (6). The falling-prevention plug prevents the falling accident of instruments due to misoperation during oil-water well testing, so as to ensure normal production of an oil-water well and reduce testing loss. The falling-prevention plug has the advantages of simple and reliable structure, low manufacturing and use costs, easy and smooth operation, convenient use, and low labor consumption, and can remarkably improve the safety performance of oil-water well testing work.
Description
Technical field:
The utility model relates to a kind of oil water well test plug, especially anti-lost plug.
Background technique:
In oil drilling and the oil recovery, when carrying instrument in the test, should stop and forget that parking waits misoperation as taking place, be that instrument enters behind the lubricator still when last carrying, cable or steel wire are broken, plug pulls off, instrument also can break away from plug, falls the problem of instrument accident, causes oil recovery well test loss.
Technology contents:
The purpose of this utility model is the special-purpose plug of a kind of well logging of design, falls the problem of instrument accident when mainly solving oil water well test because of misoperation, promptly anti-lost plug.
The measure that realizes the present utility model purpose comprises: rear body is the side of revolving, body portion hollow cavity bottom is stage clip fixedly, pressure pad is close to stage clip, and the dead bolt bottom is close to pressure pad, and dead bolt head outer side surface becomes the conical surface to be adjacent to the inboard frustum that forms that shrinks of body portion hollow cavity opening end.
Advantage of the present utility model is: fall the problem of instrument accident when solving oil water well test because of misoperation, to guarantee the oil/water well ordinary production and to reduce the test loss.The well logging work safety significantly strengthens, and is easy to use, laborsaving, easily grasps.Structure is concisely reliable, manufacturing cost and use cost economy, and it is smooth and easy to work.
Description of drawings:
Fig. 1 is the utility model embodiment 1 a structural representation
Reference character comprises: the side of revolving 1, seal ring 2, stage clip 3, pressure pad 4, dead bolt 5, body 6, working barrel 7, revolve hole 8.
Embodiment:
Embodiment 1: body 6 rear portions are the side of revolving 1, and body 6 anterior hollow cavity bottoms are stage clip 3 fixedly, and pressure pad 4 is close to stage clip 3, and dead bolt 5 bottoms are close to pressure pad 4, and dead bolt 5 head outer side surfaces become the conical surface to be adjacent to the inboard frustum that forms that shrinks of body 6 anterior hollow cavity opening ends.
Entad shrink in the anterior hollow cavity opening ends of body 6 outside, with the dead bolt 5 heads outside common conical seat surface that forms of the conical surface entad.
In use, when carrying instrument in the test, the misoperation situation is taking place, forget when stopping as stopping, be still will be with instrument after instrument enters lubricator at last portable cable or steel wire, entad shrink the conical seat surface horn mouth that forms by the body 6 anterior hollow cavity opening end outsides, compression press spring 3 presses down and struts dead bolt 5 in body 6 anterior hollow cavities, enters plug inside, and then by dead bolt 5 front end inside protrusions kaysers, at stage clip 3, under the synergy of pressure pad 4 and two semi-circular dead bolts 5, the mushroom head of instrument, the rope socket head is locked in the plug firmly, even cable or steel wire are broken, instrument can not break away from plug yet, thereby realizes anti-lost function.
When solving oil water well test, present embodiment falls the problem of instrument accident, to guarantee the oil/water well ordinary production and to reduce the test loss because of misoperation.The well logging work safety significantly strengthens, and is easy to use, laborsaving, easily grasps.Structure is concisely reliable, manufacturing cost and use cost economy, and it is smooth and easy to work.
