Background technology
Conventional belt oil-well pump technique, when needs put oil pipe Operating Pressure, cannot effectively be opened after cannot effectively closing or close due to oil pipe inner passage, causing Operating Pressure needs cannot effectively open, causing Operating Pressure needs to carry out kill-job operation, pit shaft is poured into the well killing fluid of design flow with the kill-job of certain weight proportion, is higher than stratum hydraulic coupling by well killing fluid proportion, prevent gas blowout accident occur during operation.Well killing fluid proportion is too high to be polluted stratum and cause oilwell produced fluid amount drastically to decline in short term.
The content of the invention
It is an object of the invention to provide the device and its operating method of a kind of no killing well oil pumping operation maintenance self-closed oil stream; its is rational in infrastructure; dependable performance; well killing fluid can not be used to close oil flow channel; reduce production cost; reduce the workover treatment time; improve job execution environment, prevent in workover treatment, crude oil overflows well head from oil pipe; or blowout; cause environmental pollution and unnecessary loss, it is ensured that environmental protection operation, reduce influence of the mud to stratum; protection maintains the original production capacity on stratum, for the long period of development and steady production in oil field provide basis.
The object of the present invention is achieved like this：A kind of device of no killing well oil pumping operation maintenance self-closed oil stream,It is included in coordinate in oil pipe and plunger oil-well pump is installed,Oil pipe the pump line of plunger oil-well pump by sleeve pipe connection,The lower port closing of pump line,Symmetrical through hole is set on the tube wall of pump line,Affixed connecting tube on the oil pumping hole of its lower surface of plunger oil-well pump being engaged with pump line,The sealing of hole piston tube being engaged with pump line is connected to by the on-off connector installed in connecting tube,The working hole being engaged with pump line lower end tube wall through hole is set at the middle part of sealing of hole piston tube,Sealing ring is respectively mounted in the seal groove being uniformly arranged in sealing of hole piston tube,Sealing piston pipe is engaged by sealing ring with pump line,Sealing of hole piston tube is divided into upper piston pipe and lower piston pipe by the working hole of sealing of hole piston tube,When shifting in sealing of hole piston tube,The tube wall through hole of lower piston duct occlusion pump line,Realize closing oil stream.
A kind of operating method of the device of no killing well oil pumping operation maintenance self-closed oil stream has the following steps：
1、
Before decentralization oil well pump, first oil pipe decentralization in place, now, upper and lower piston tube is already installed on the bottom of oil pipe, and working hole is in the upper of tube wall through hole, and coordinates with oil pipe, belongs to closed mode；
2、
Decentralization higher level's rod string and oil well pump, on-off connector is equipped with the affixed connecting tube in hole of pumping of oil well pump lower end；
3、
Oil well pump is persistently transferred, and on-off connector achieves a butt joint with upper piston pipe, and upper and lower piston tube is pressed downward by higher level's rod string together, until working hole and tube wall through hole overlap, open mode is realized, is started pumping unit of well mouth and is driven the upper and lower motion of sucker rod, underground fluid enters in oil pipe from pump line side；
4、
During closing, oil well pump is above carried, upper and lower piston tube is increased with rod string together by connecting tube, until working hole reaches the upper of tube wall through hole, that is, realize closed mode；Now on-off connector is disengaged, and oil well pump and on-off connector continue up with rod string together, and miscellaneous part is stayed in pump line.
Operation principle of the invention：
The present invention is lifted by from well head to sucker rod, lowering operation, drives oil pump plunger piston to be axially moved.So as to drive sealing of hole piston tube to move up and down, closing, opening operation are realized.
When closing oil flow channel is needed, the on-off connector in connecting tube is disengaged the present invention, and sealing of hole piston tube rises closes working hole, realizes closing oil flow channel；When needing to open oil flow channel, the on-off connector docking in connecting tube, sealing of hole piston tube declines, and working hole is opened, and realizes that oil flow channel is unimpeded.
The good effect that the present invention is produced：
Production cost can be reduced, the workover treatment time is reduced, improves job execution environment, prevented in workover treatment, crude oil overflows well head, or blowout from oil pipe, causes environmental pollution and unnecessary loss, it is ensured that environmental protection operation.Influence of the mud to stratum is reduced, and protection maintains the original production capacity on stratum, for the long period of development and steady production in oil field provide basis.
The present invention is rational in infrastructure, dependable performance, realize and do not use well killing fluid closing oil flow channel, reduce production cost, reduce the workover treatment time, improve job execution environment, prevent in workover treatment, crude oil overflows well head, or blowout from oil pipe, cause environmental pollution and unnecessary loss, it is ensured that environmental protection operation.Influence of the mud to stratum is reduced, protection maintains the original production capacity on stratum, for the long period of development and steady production in oil field provide basis.
