Abstract
A kind of automatic ball-and-seat of electric submersible pump, it is related with oil exploration equipment, including pipeline (1), electric submersible pump (6), ball-and-seat, the ball-and-seat is located at the top of electric submersible pump (6), its sealed connection sequence is from top to bottom: pipeline (1) --- ball-and-seat --- pipeline (1) --- electric submersible pump (6) --- pipeline (1), ball-and-seat passes through ten root canal roads, total pipeline (1) for being about 96 meters and electric submersible pump (6) are tightly connected, the structure of the ball-and-seat is in ball-and-seat enclosure interior: sealing ring (5) periphery is provided with valve seat (3), sealing ring (5) top is provided with sphere (4) that can be up and down, apart from sphere (4) top, 1 centimeters are provided with spacer pin (2).Effect is: can increase ball-and-seat at a distance from electric submersible pump, the gas generated when gas lock is enable smoothly to move up, increase liquid into pump volume after conceding volume, release gas lock phenomenon；And the structure of ball-and-seat is improved, improve the job stability of ball-and-seat.
Description
Technical field
The utility model is related with oil exploitation, and in particular to a kind of automatic ball-and-seat of electric submersible pump.
Background technique
The steady production of submersible electric pump well plays a very important role the completion of yield task.Traditional oil exploitation
Ball-and-seat is also installed, but structure is complicated for ball-and-seat on the electric submersible pump used, is easy to appear failure, and the position of ball-and-seat exists
9.6 meters of electric submersible pump top position (a root canal road upper position), since some oil wells belong to, strata pressure is low, and gas-oil ratio is high, produces
The high oil well of liquid measure, degassing seriously easily causes the frequent gas lock of electric pump well in process of production, and gas causes empty load of motor to be transported into pump
The phenomenon that turning, cable breakdown, motor is caused to burn out increases inspection pump maintenance cost, serious shadow so that oil well repair free period shortens
Oil well is rung steadily to produce.The method of traditional solution electric pump gas lock is main 4 following: first is that being built the pressure repeatedly by well head solves degasification
Lock；Second is that being vented oil jacket pipe pressure by termination of pumping, gases affect is released by stratum energy, then turn on pump produces；Third is that casing
Fluid infusion injects certain liquid measure degassed crude by press device, increase pump inlet pressure, to release gas lock；Fourth is that adjustment
Manufacturing parameter (oil nozzle, frequency etc.).But the above measure reduces rate when driving a well, and the measure effect period is short, inherently not
Gas lock phenomenon can be released, electric pump well lost units is caused.
Summary of the invention
The technical issues of utility model solves is: electric submersible pump is easy gas lock, because electric immersible pump well loses caused by gases affect
Yield.Ball-and-seat work is not sufficiently stable, and failure is more.
The utility model the technical solution adopted is that: a kind of automatic ball-and-seat of electric submersible pump, including pipeline, electric submersible pump, Dan Liu
Valve, the ball-and-seat are located at the top of electric submersible pump, and sealed connection sequence is from top to bottom: pipeline --- ball-and-seat --- pipe
Road --- electric submersible pump --- pipeline, it is characterized in that: ball-and-seat, by ten root canal roads, total pipeline for being about 96 meters and electric submersible pump are close
Envelope connection, structure of the ball-and-seat in ball-and-seat enclosure interior are as follows: sealing ring periphery is provided with valve seat, and sealing ring top is set
It is equipped with sphere that can be up and down, 1 centimeters are provided with spacer pin apart from sphere top.
The beneficial effect of the practical utility model is: increasing ball-and-seat at a distance from electric submersible pump, makes electric submersible pump and ball-and-seat
The gas compartment in pipeline becomes larger, and increases gas storage volume, so that the gas generated when gas lock is smoothly moved up, increase after conceding volume
Liquid releases gas lock phenomenon into pump volume；And the structure of ball-and-seat is improved, improve the job stability of ball-and-seat.
Detailed description of the invention
Fig. 1 is the side view of the utility model.
In figure: 1, pipeline, 2, spacer pin, 3, valve seat, 4, sphere, 5, sealing ring, 6, electric submersible pump.
Specific embodiment
In Fig. 1, a kind of automatic ball-and-seat of electric submersible pump, including pipeline 1, electric submersible pump 6, ball-and-seat, the ball-and-seat position
In the top of electric submersible pump 6, sealed connection sequence is from top to bottom: --- ball-and-seat --- pipeline 1 --- electric submersible pump of pipeline 1
6 --- pipeline 1, ball-and-seat are tightly connected by ten root canal roads, total pipeline 1 for being about 96 meters and electric submersible pump 6, single stream
The structure of valve is in ball-and-seat enclosure interior: 5 periphery of sealing ring is provided with valve seat 3, and 5 top of sealing ring is provided with and can live up and down
Dynamic sphere 4, apart from 4 top of sphere, 1 centimeters are provided with spacer pin 2.
