Abstract
The utility model relates to a horn mouth tool for plugging of oil wells. The horn mouth tool comprises a cylindrical body, wherein a horn-shaped through hole is formed in the body; a thread is arranged at one end, at which the cross section of the through hole is smaller, of the body; an aluminum valve core is arranged at the other end of the body; and a plugging block is connected with the body through pins. The horn mouth tool, which is a tubing plug, is simple in structure and higher in practicability.
Description
Technical field
The utility model relates to a kind of oil well and takes out the stifled horn mouth instrument of using.
Background technology
Snubbing serving is to have under the state of pressure at well head, utilizes special snubbing serving device and supporting calker under the cooperation of routine work machine, to carry out not kill-job to rise a kind of operational method of lower tubular column.Capital equipment is comprised of Hoisting System, annular space sealing system, anti-top system, tubing string sealing system.Its needs and the cooperatively interacting to realize and play lower tubular column operation under environment with pressure of pipe column blanking plug, and the pressure dependence blanking plug in tubing string is controlled.But with respect to complicated geological environment, when field produces tubular column structure is complicated, existing blanking plug can not meet need of production.
Summary of the invention
The utility model is intended to propose the good tubing plug of a kind of plugging effect.
A kind of horn mouth instrument described in the utility model, comprises cylindrical body, is provided with a horn-like through hole in body, and body is provided with screw thread in the less one end of through hole cross section, and the other end is provided with aluminium matter spool, and described plugging block is connected by pin with body.
Horn mouth instrument described in the utility model, simple in structure, practicality is stronger.
Accompanying drawing explanation
Fig. 1 is sectional view of the present utility model.
1-through hole in figure; 2-aluminium matter spool; 3-body.
The specific embodiment
A kind of horn mouth instrument, comprises cylindrical body 3, is provided with a horn-like through hole 1 in body 3, body 3 is provided with screw thread in the less one end of through hole cross section, the other end is provided with aluminium matter spool 2, and described plugging block is connected by pin with body 3, during work, horn mouth instrument is screwed onto to the foot of operating tool string, down to design attitude, the 5MPa that just pressurizeing, destroys aluminium matter spool 2, can complete the lower interior obstruction stifled, that note the tubing strings such as ash of squeezing, meet cable and cross coiled tubing test and other technological requirements.
