Abstract
The invention relates to a horn mouth tool used for pumping and plugging of an oil well. The horn mouth tool comprises a cylindrical body, wherein a horn-shaped through hole is formed in the body, threads are arranged at the end which is smaller in the cross section of the through hole, an aluminum valve element is arranged at the other end, and a plugging block is connected with the body through dowels. An oil piping plug is simple in structure and high in practicability. The horn mouth tool is simple in structure and high in practicability.
Description
Technical field
The present invention relates to a kind of oil well and take 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-purpose snubbing serving device and supporting calker under the cooperation of routine work machine, to carry out a kind of operational method that not kill-job plays 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 under environment with pressure and play lower tubular column operation 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 present invention is intended to propose the good tubing plug of a kind of plugging effect.
A kind of horn mouth instrument of the present invention, comprises cylindrical body, is provided with a horn-like through hole in body, and body is provided with screw thread in through hole cross section compare little one end, and the other end is provided with aluminium matter spool, and described plugging block is connected by pin with body.
Horn mouth instrument of the present invention, simple in structure, practicality is stronger.
Accompanying drawing explanation
Fig. 1 is sectional view of the present invention.
1-through hole in figure; 2-aluminium matter spool; 3-body.
The specific embodiment
An 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 through hole cross section compare little one end, 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.
