Abstract
The utility model relates to a blowout-preventing oil pumping pipe capable of washing a well, consisting of an oil pipe, a sleeve pipe, an oil pump and a packer. The oil pipe, the oil pump, a well washing and shunting valve and the packer are connected in sequence and arranged in the sleeve pipe; the well washing and shunting valve is provided with a well washing channel and an oil flow channel; and an oil pipe anchor oil draining device is connected onto the oil pump. The oil flow at the lower part of the well washing and shunting valve can flow to the upper part of the well washing and shunting valve, the oil flow in the well washing and shunting valve can not flow into the sleeve pipe, and the liquid flow in the sleeve pipe can flow into the well washing and shunting valve, therefore, the utility model can prevent stratigraphic oil flow from being blown out of the sleeve pipe, prevent a stealer from draining oil from the sleeve pipe to steal the oil, and can make liquid entering the sleeve pipe flow in from the well washing and shunting valve and flow out from the oil pump and the oil pipe, so as to form reverse circulation passage well washing. The utility model has marked economic benefit.
Description
One, technical field
The utility model is the tubing string that oil field pumping well is used, and is a kind of blowout prevention washing well pumping pipe string.
Two, background technology
Because formation leakage, for normal well-flushing, generally divide into a packer and UNICOM's screen casing, but this pumping pipe string can well-flushing but can not blowout prevention at tubing string, thief can sleeve pipe can oil spout the aboveground stolen of draining the oil, cause the crude oil loss; Existing another kind of pumping pipe string can prevent that fluid from spraying in sleeve pipe, but does not have the well-flushing passage, can not well-flushing, and make the oil well can not ordinary production.
Three, summary of the invention
The purpose of this utility model is a kind of blowout prevention washing well pumping pipe string of design, can well-flushing, can blowout prevention, and the oil well production time is long, and thief can not be in the aboveground stolen of draining the oil of sleeve pipe energy oil spout.
The purpose of this utility model is achieved in that by oil pipe, sleeve pipe, oil well pump, packer to be formed, oil pipe, oil well pump, shunting flushing valve, packer connect successively, oil pipe, oil well pump, shunting flushing valve, packer are in the sleeve pipe, on the shunting flushing valve well-flushing passage and oil flow channel are arranged.
Connect the tubing anchor bleeder on the oil well pump.
The beneficial effects of the utility model are: can prevent that formation oil stream from spraying in sleeve pipe, the stolen thereby the molecule that can avoid theft is drained the oil at the sleeve pipe place can form anti-circulation canal well-flushing, so the utlity model has remarkable economic efficiency.
Four, description of drawings
Accompanying drawing is the assembling drawing of the utility model embodiment.
Five, the specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described.
Form by oil pipe 1, sleeve pipe 2, oil well pump 4, packer 6, oil pipe 1, oil well pump 4, shunting flushing valve 5, packer 6 connect successively, oil pipe 1, oil well pump 4, shunting flushing valve 5, packer 6 are in the sleeve pipe 2, on the shunting flushing valve 5 well-flushing passage 7 and oil flow channel 8 are arranged.Connect tubing anchor bleeder 3 on the oil well pump 4.
The oily stream of shunting flushing valve 5 bottoms can flow to top, the oily stream of shunting flushing valve 5 inside can not flow in the sleeve pipe, liquid stream in the sleeve pipe can flow in the shunting flushing valve 5, therefore, the utility model can prevent that formation oil stream from spraying in sleeve pipe, the stolen thereby the molecule that can avoid theft is drained the oil at the sleeve pipe place is squeezed into liquid in the sleeve pipe 2 and entered from shunting flushing valve 5, flow out from oil well pump 4, oil pipe 1, form anti-circulation canal well-flushing.
Claims (2)
1, blowout prevention washing well pumping pipe string, form by oil pipe (1), sleeve pipe (2), oil well pump (4), packer (6), it is characterized in that: oil pipe (1), oil well pump (4), shunting flushing valve (5), packer (6) connect successively, oil pipe (1), oil well pump (4), shunting flushing valve (5), packer (6) are in the sleeve pipe (2), on the shunting flushing valve (5) well-flushing passage (7) and oil flow channel (8) are arranged.
