Description
Technical field
The utility model relates to the oil well pump field used in oil field, it is specifically a kind of just setting double standing valve ball frustum type can
Draining oil well pump.
Background technique
Oil well pump is the important downhole tool that crude oil is given rise to ground, in pump detection and workover, in pump barrel and top oil pipe
Crude oil can not release, and taking ground to will increase environmental protection construction investment and environmentally friendly risk.The existing dress realizing crude oil in oil pipe and releasing
There are mainly two types of setting, one is bleeder is installed additional in the case where pumping upper tubing string or pump, another kind is oil drain pump.
Wherein the application of bleeder has the following problems: first is that the bleeders such as the sleeve type installed additional on pump, rotary cannot
It fully achieves pump barrel and crude oil in oil pipe releases, and mechanically actuated success rate is low.Second is that pump is lower to install hammering oil discharger additional, by
Viscosity of crude, wax deposition situation etc. influence, and bleeder draining success rate is low, draining speed is slow.Third is that the oil leak hole of bleeder needs
It seals, corrosive environment caused by the temperature, pressure and dosing by underground complexity is influenced, and easily there are problems that poorly sealed leakage.Four
It is install bleeder additional at high cost, promotes that investment is big, consumption is big, the period is long, it can not overall application.
The application of existing oil drain pump has the following problems: first is that oil drain pump of the oil leak hole on pump barrel wall top, long pump barrel
The crude oil of lower part can not release completely.Second is that throwing the oil drain pump that bar hits draining pin, substantially oil well pump is let out with impacting type
The combining form of oily device has that hammering oil discharger draining success rate is low, draining speed is slow.Third is that decentralization plunger rotation
Formula oil drain pump is operated by mechanical rotary sucker rod and is realized, easy damaged roofbolt；And the rubber material that draining channel seal uses
Matter, in underground the Temperature-pressure Conditions of complexity and add chemical agent viscosity reduction in the environment of, be easy to appear leakage.Fourth is that using pulling method
Oil drain pump, drainage device is opened by force by pulling and running tool, not only to increase flow charts, increase operating cost, there is also uses more
Rubber material sealing draining duct the Temperature-pressure Conditions of underground complexity and plus in the environment of chemical agent viscosity reduction, be easy to appear
Leakage problem, and mechanical fishing success ratio is low.
The reason of can not releasing from pump barrel when causing pump detection and workover and top crude oil in oil pipe, is analyzed it is found that having its source in pumping
Fixed valve ball is set in the fixed valve assembly of oil pump, it is currently used can draining oil well pump mainly realized in the form of aperture itself
Draining, there is no solve the problems, such as that oil well pump can draining from the root.
Summary of the invention
Pump barrel and top crude oil in oil pipe can not release completely when in order to overcome the shortcomings of existing pump detection and workover, this is practical
It is novel provide it is a kind of just setting double standing valve ball frustum type can draining oil well pump, double standing valve ball frustum type is just being set using this can draining
Oil well pump when pump detection and workover, after sucker rod and plunger rise, can open fixed valve ball by simply just suppressing operation,
Drain path is opened, leaks into crude oil in oil pipe completely in oil jacket space.
The technical solution of the utility model is: one kind just setting double standing valve ball frustum type can draining oil well pump, including above connect
Head, top connection bottom connect pump barrel, and pump barrel bottom is connected with lower contact, and lower contact bottom is connected with fixed valve top connection, described
Fixed valve top connection bottom is connected with frustum drum, and frustum drum is internally connected with standing valve cover, and standing valve cover bottom is equipped with fixed valve
Ball, fixed valve ball bottom are equipped with fixed valve base, several longitudinal drain paths are provided on frustum drum, are led to inside the frustum drum
It crosses pin and is connected with draining valve ball pressure cap, draining valve ball pressure cap bottom is equipped with draining valve ball, and draining valve ball bottom is equipped with gate gurgle valve
Seat, frustum drum outside is connected with draining valve bonnet, and has gap between frustum drum bottom surface and draining valve bonnet.
The utility model has the following beneficial effects: pump is interior not to be remained by adopting the above scheme, (1) draining effect is good
Crude oil solves the problems, such as that crude oil can not release completely in oil pipe and pump barrel from the root；(2) draining success rate is high, by right
Oil pipe is just suppressing mode and is opening pump bottom draining valve ball, compared to mechanical means such as shock, rotation, salvagings, not by viscosity of crude and knot
Wax situation influences；(3) sealing effect is good, and setting for bivalve ball is realized by the precision-fit of valve ball and valve seat, pin
Place and eccentric cylinder are without addition sealing ring, without considering the influence of underground Temperature-pressure Conditions and additional chemical agent to sealing；(4)
It does not influence to suppress the verification of the oil pumping pumps condition such as pump, well-flushing, processing work；(5) purpose that cleaning tubing inner wall can be achieved, just suppresses height
Crude oil in oil pipe is replaced flowline by warm water, and tube inner wall is cleaned, and the water in oil pipe need to only be released by acting process；(6)
It may be reused, only need to change pin, do not have to consider sealing problem.
