Abstract
The utility model relates to an oil field down-hole operation tool, in particular to an oil well displacing mud well dredging device. According to the technical scheme, the oil well displacing mud well dredging device comprises an upper joint, a drift size gauge body and a short section; one end of the drift size gauge body is connected with the upper joint, the other end of the drift size gauge body is connected with the short section, a well dredging tubular column is arranged in the drift size gauge body, the well dredging tubular column is composed of a sealing ring, a small circular hole, a spring and a circular hole, the sealing ring is arranged at the connecting position of the well dredging tubular column and the drift size gauge body, the small circular hole is formed in one end of the well dredging tubular column, the circular hole is formed in the other end of the well dredging tubular column, the spring is arranged outside the well dredging tubular column, and retaining rings are arranged at the two ends of the spring. The oil well displacing mud well dredging device has the advantages that mud in a new well is completely recycled or displaced in a mud pool, the environment is improved, the safety of the work of construction personnel is guaranteed, the working efficiency is improved, the environment is protected, and economical benefits and social benefits are achieved.
Description
Technical field
The utility model relates to a kind of tools for downhole of oil field, and particularly a kind of oil well is for slurry drifting device adopting.
Background technology
At present, when oilfield downhole operation brings in a well, need drifting with for slurry work, during lower tubular column, easily there is the excessive or overflow of mud, cause well head and near environment pollution; Easily there is security incident in operating worker, causes personal security can not be guaranteed, and flow chart speed slowed down, decrease in efficiency.
Summary of the invention
The purpose of this utility model is exactly in view of the foregoing defects the prior art has, provides a kind of oil well for slurry drifting device adopting.
Its technical scheme is: comprise top connection, drift size gauge tool body, pipe nipple, one end of drift size gauge tool body connects top connection, the other end of drift size gauge tool body connects short circuit, the inside of described drift size gauge tool body is provided with drifting tubing string, described drifting tubing string is comprised of sealing ring, circulation aperture, spring, circulation port, baffle ring, the junction of drifting tubing string and drift size gauge tool body is provided with sealing ring, one end of drifting tubing string is provided with circulation aperture, the other end of drifting tubing string is provided with circulation port, the outside of drifting tubing string is provided with spring, and the two ends of described spring are provided with baffle ring.
The beneficial effects of the utility model are: the mud in new well all reclaimed or replace into mud pit, improving environment, constructor's work safety is guaranteed, and increase work efficiency, and protection of the environment, obtains economic benefit and social benefit.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model;
Accompanying drawing 2 is structure charts of the drifting tubing string of inside of the present utility model;
In upper figure: top connection 1, drift size gauge tool body 2, pipe nipple 3, sealing ring 4, circulation aperture 5, spring 6, circulation port 7, baffle ring 8, drifting tubing string 9.
The specific embodiment
By reference to the accompanying drawings 1 and 2, the utility model will be further described:
The utility model comprises top connection 1, drift size gauge tool body 2, pipe nipple 3, one end of drift size gauge tool body 2 connects top connection 1, the other end of drift size gauge tool body 2 connects short circuit 3, the inside of described drift size gauge tool body 2 is provided with drifting tubing string 9, described drifting tubing string 9 is by sealing ring 4, circulation aperture 5, spring 6, circulation port 7, baffle ring 8 forms, drifting tubing string 9 is provided with sealing ring 4 with the junction of drift size gauge tool body 2, one end of drifting tubing string 9 is provided with circulation aperture 5, the other end of drifting tubing string 9 is provided with circulation port 7, the outside of drifting tubing string 9 is provided with spring 6, the two ends of described spring 6 are provided with baffle ring 8.
When slurry tubing string is replaced in the lower drifting that brings in a well, mud easily sprays in wellhead casing pipe and oil pipe, cause near well head and the pollution of equipment, use the utility model, in oil pipe, can there is not mud ejection, mud can flow out from sleeve pipe two side gates, enter mud pit or recycling can, improved operating environment, during lower oil pipe, this device is connected to oil pipe bottom, enter in mud, inner part is subject to mud suspension effect up, sealing ring sealed inner, mud slowly enters oil pipe from circulation port, lower oil pipe speed is fast, it is slow that mud enters oil pipe, formation time is poor, mud is got rid of well head from annular space, through experiment is installed, prove that this tool construction is simply applicable to underground work field popularization application.
