Description
Technical field
The utility model belongs to the equipment that oil flow channel is closed in oil extraction in oil field workover treatment, particularly a kind of device of no killing well oil pumping operation maintenance self-closed oil stream.
Background technology
Conventional belt oil-well pump technique, when needing to carry out putting oil pipe Operating Pressure, cannot effectively open after effectively cannot closing due to oil pipe inner passage or closing, Operating Pressure needs are caused to carry out effectively opening, Operating Pressure is caused to need to carry out kill job, namely with the kill-job of certain weight proportion, pit shaft is poured into the well killing fluid of design flow, by well killing fluid proportion higher than stratum hydraulic coupling, prevents from occurring gas blowout accident during operation.Well killing fluid proportion is too high can be polluted stratum and cause oilwell produced fluid amount short-term sharply to decline.
Utility model content
The purpose of this utility model is the device providing a kind of no killing well oil pumping operation maintenance self-closed oil stream; it is rational in infrastructure; dependable performance; well killing fluid can not be used to close oil flow channel; reduce cost of production; reduce the workover treatment time; improve job execution environment, prevent when workover treatment, crude oil overflows well head in oil pipe; or blowout; cause environment pollution and unnecessary loss, ensure environmental protection operation, reduce the impact of mud formation; protection maintains the original production capacity on stratum, for the long period of development in oil field and steady production provide basis.
The purpose of this utility model is achieved in that the device of a kind of no killing well oil pumping operation maintenance self-closed oil stream, be included in oil pipe to coordinate and plunger oil-well pump is installed, oil pipe is connected to the pump line of plunger oil-well pump by sleeve pipe, the lower port of pump line is closed, the tube wall of pump line arranges symmetrical through hole, affixed tube connector on the oil pumping hole of its lower surface of plunger oil-well pump of matching with pump line, the sealing of hole piston tube matched with pump line is connected to by the on-off connector that tube connector is installed, the working hole matched with pump line lower end tube wall through hole is set at the middle part of sealing of hole piston tube, respectively sealing ring is installed in the seal groove of uniform setting in sealing of hole piston tube, packed-piston pipe is matched with pump line by sealing ring, 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 sealing of hole piston tube is moved, the tube wall through hole of lower piston duct occlusion pump line, realize closing oil stream.
Operating principle of the present utility model:
The utility model by promoting from well head sucker rod, lowering operation, drive oil pump plunger piston axially-movable.Thus drive sealing of hole piston tube to move up and down, realize closedown, opening operation.
The utility model is when the closed oil flow channel of needs, and the on-off connector on tube connector is thrown off, and sealing of hole piston tube rises and closed by working hole, realizes closing oil flow channel; When oil flow channel opened by needs, the on-off connector docking on tube connector, sealing of hole piston tube declines, and working hole is opened, and realizes oil flow channel unimpeded.
The concrete course of work is as follows:
(1), before transferring oil well pump, first tubing string is transferred and put in place.At this moment, upper piston pipe, working hole, lower piston pipe have been arranged on oil pipe bottom, and working hole is in the upper of tube wall through hole, and coordinates with oil pipe, belongs to closed condition.
(2) after tubing string is transferred, then oil well pump and higher level's rod string is transferred.At this moment, on the oil pumping hole of oil well pump lower surface, affixed tube connector, tube connector is equipped with on-off connector.
(3) oil well pump continues to transfer, and first on-off connector achieves a butt joint with upper piston pipe.Continue to transfer oil well pump, upper piston pipe, working hole, lower piston pipe, together by higher level's roofbolt to pressing down, until working hole and tube wall through hole overlap, realize open mode.
At this moment, start pumping unit of well mouth, drive the upper and lower motion of sucker rod, down-hole fluid can enter in oil pipe from oil pipe side.
On when carrying oil well pump, by carry rod string, drive plunger oil-well pump to rise.
Tube connector, on-off connector, upper piston pipe, working hole, lower piston pipe, rise with rod string together, until working hole arrival tube wall through hole is upper, i.e. closed condition.
At this moment, on-off connector is thrown off, and oil well pump, tube connector 3 and on-off connector 4, continue with rod string up together, miscellaneous part is stayed in tubing string.
The good effect that the utility model produces:
Can reduce cost of production, reduce the workover treatment time, improve job execution environment, prevent when workover treatment, crude oil overflows well head in oil pipe, or blowout, causes environment pollution and unnecessary loss, ensures environmental protection operation.Reduce the impact of mud formation, and protection maintains the original production capacity on stratum, for the long period of development in oil field and steady production provide basis.
The utility model is rational in infrastructure, dependable performance, achieve and do not use well killing fluid to close oil flow channel, reduce cost of production, decrease the workover treatment time, improve job execution environment, prevent when workover treatment, crude oil overflows well head in oil pipe, or blowout, cause environment pollution and unnecessary loss, ensure that environmental protection operation.Decrease the impact of mud formation, protection maintains the original production capacity on stratum, for the long period of development in oil field and steady production provide basis.
