The upper end and the lower end of the four-way sleeve of the well opening are arranged to be flanges connected with a pipeline, the sealing grooves (1 and 12) and the connection holes (2 and 13) are arranged on the flanges on the two end faces, the two oil discharging holes (5 and 17) are radially arranged in the middle of the four-way sleeve of the well opening, the screw connection holes (4 and 15) and the sealing grooves (6 and 16) are arranged on the end faces of the oil discharging holes (5 and 17), and the two drum type holes (11 and 18) are arranged in the through-diameter inner holes.

Description

Well head four-way sleeve pipe
Technical field
The utility model relates to the four-way sleeve pipe, is specifically related to a kind of well head four-way sleeve pipe, is applicable to the shunting and the guiding of oil, saline solution, mirabilite, natural gas extraction well head.
Background technology
The exploitation of present underground fluid resource has developed into tertiary recovery, and primary oil recovery is a natural ability of leaning on stratum itself, ejects ground to oil, and tar productivity is very low, tar productivity 5%; After natural ability drops to a certain degree, at this time, improve the pressure on stratum just by water filling in oil reservoir, through improving pressure, to extrude oil water from the stratum, this is a secondary oil recovery, tar productivity 40%; Developed at present to the stratum injection of polymer, leaned on chemical agent to come out oil wash, tar productivity is very high.These three kinds of oil production methods, the pressure ratio on stratum is higher, and especially back two kinds of oil production method strata pressures are higher.Traditional well head four-way sleeve pipe, inner surface is columniform straight hole, when the fluid of underground high-voltage high-speed passes through well head four-way sleeve pipe; The shunting of bump both sides is taken over, and produces vibration, and the long-play connecting bolt is loosening; Cause leakage phenomenon, very easily cause fire, the safety of harm people and equipment.
Summary of the invention
The purpose of the utility model is: a kind of well head four-way sleeve pipe is provided; The inner chamber of four-way sleeve pipe is arranged to be a bit larger tham inner chamber latus rectum cydariform hole; Be installed on the pipeline of fluid issuing, play the vibrations of cushioning effect and absorption portion, avoid bolt looseness to cause leakage phenomenon.
The technical scheme that the utility model technical solution problem is taked is: well head four-way sleeve pipe comprises: seal groove, connecting hole, inner conical surface, threaded connection hole, oil outlet, seal groove, interior cylindrical hole, upper surface, interior cylindrical hole, inner conical surface, cydariform hole, seal groove, connecting hole, last cylindrical, threaded connection hole, seal groove, oil outlet, cydariform hole, cylindrical hole, cylindrical hole and lower surface; Well head four-way sleeve pipe is arranged to and pipeline flange connecting dish at two ends up and down; The flange of both ends of the surface is provided with seal groove and connecting hole; Well head four-way sleeve pipe middle part radially is provided with two oil outlets, and the end face of oil outlet is provided with threaded connection hole and seal groove.
In the well head four-way sleeve pipe of the utility model, two cydariform holes are set in the latus rectum endoporus.
The utility model beneficial effect is: the vibration of buffering absorption portion, and avoid bolt looseness to cause leakage phenomenon; Simple in structure, intensity increase, safe and reliable.
