Description

Bidirectional four-way synergy tool

Technical Field

The utility model discloses a bidirectional four-way synergistic tool, and belongs to the technical field of bidirectional four-way synergistic tools.

Background

The current oil pump has low pump efficiency and does not have the gas-proof function, and the existing gas-proof oil pump, synergy technology, gas-proof device, normal washing device, oil drainage device and the like are independent products, so that the tools are required to be used together in series, and the cost is seriously wasted.

And the prior art products have different serious defects, and the brief array is as follows:

most of the existing anti-gas pumps are only provided with gas anchors under the pumps to realize anti-gas; the existing technologies such as a loop valve anti-air pump and a multi-section plunger anti-air pump are also used as schemes for making a valve pair of the oil pump open and close strongly, so that the problem of gas conversion in a cavity at the lower part of the plunger is not really solved; the existing individual advanced anti-gas pump is provided with a sealed gas bag outside the pump barrel, but only the gas under the plunger is converted into the pipe column above the plunger in function, so that the conversion efficiency is low, and the gas cannot be discharged to the oil jacket annulus outside the pipe column.

The existing oil drain pump adopts a long plunger short pump barrel, an oil drain hole is formed in the short pump, the oil drain hole does not have an air-proof function, a connecting pipe below the pump barrel is not in sealing fit with a plunger, a large cavity gap is formed between the outer diameter of the plunger and the inner wall of the connecting pipe, the purpose of vacuumizing cannot be achieved when the plunger pumps, and an air lock phenomenon can be formed after a large amount of air is accumulated in the cavity.

Most of the existing oil drainage devices adopt an impact opening mode, the shear pins of the oil drainage devices are broken through the gravity impact rod thrown into the wellhead to realize oil drainage, and impact oil drainage failures are often caused by the resistance of liquid in a pipe column, the blocking of silt and scale blocks deposited in the oil drainage devices and other reasons in actual use.

The existing pressure opening type oil drain device needs large-scale equipment such as a ground provided operation vehicle and the like, and the oil drain device often fails in oil drain due to rust, scale and the like.

Most of the existing well-flushing devices open oil drainage channels through pressure or mechanical feelers, and in actual use, key parts often fail due to scaling and corrosion of the key parts in the environments of underground hypersalinity and the like, so that well-flushing cannot be realized.

All the existing products do not have the liquid supplementing function, only the well liquid is pumped by the cooperation of the plunger and the pump barrel, and the pump efficiency is often low when gas in the well liquid is separated out.

The above is beyond the problems and disadvantages of the prior art.

Disclosure of Invention

Although embodiments of the utility model have been disclosed above, they are not limited to the use listed in the specification and embodiments. It can be applied to various fields suitable for the present utility model. Additional modifications will readily occur to those skilled in the art. Therefore, the utility model is not to be limited to the specific details and illustrations shown and described herein, without departing from the general concepts defined in the claims and their equivalents.

In the description of the present utility model, it should be noted that the term "motion" should be understood in a broad sense, and may be either pulling or lifting by external force, or may be moving by self kinetic energy, or may be moving by interaction force of electromagnetic or magnetic energy, and in specific implementation, may be considered as a phase motion between the two, and when a moving object is stationary, may be an object motion opposite to the moving object.

The specific working mode is as follows:

as shown in fig. 2, when the power piston 2 ascends in the working cylinder 1, the pulling and pressing cavity II is in a negative pressure state, the lifting cavity I is in a high pressure state, at the moment, the power valve 2.1 is closed, the sealing valve 4 is opened, at the moment, working medium enters the inside of the bidirectional four-way synergistic tool after being filtered from the outside of the suction filter 5, sand grains are deposited into the sand settling cavity IV in the sediment device 6 due to gravity, liquid enters the pulling and pressing cavity II through the sealing valve 4, liquid in the lifting cavity I is synchronously lifted upwards, at the moment, the liquid supplementing cavity III and the pulling and pressing cavity II are emptied to be full of liquid under the pressure of liquid outside the cavity, at the moment, the position of the liquid supplementing cavity III and the pulling and pressing cavity II is in an isolated state, at the moment, the power piston 2 is always in contact with the working cylinder 1 and realizes sealing, the generated vacuum degree is good, the efficiency is high, and air lock is prevented.

As shown in fig. 3, when the power piston 2 moves to the uppermost end, the lowermost end of the power piston 2 is positioned at the upper part of the functional hole 1.1, at the moment, the power valve 2.1 and the sealing valve 4 are simultaneously in a closed state, at the moment, the functional hole 1.1 loses the blocking effect of the power piston 2 and is in an open state, at the moment, the pulling and pressing cavity ii is communicated with the fluid supplementing cavity iii, and the fluid supplementing cavity iii is communicated with the oil jacket annulus, so that the pressure receiving cavity ii is directly communicated with the oil jacket annulus through the fluid supplementing cavity iii, and the state of internal and external communication is achieved.

At this time, the liquid in the oil sleeve annulus and the liquid supplementing cavity III can be rapidly introduced into the drawing and pressing cavity II, the introduced liquid in the drawing and pressing cavity II can completely replace the gas in the drawing and pressing cavity II, the discharged gas is discharged into the oil sleeve annulus through the liquid supplementing cavity III, and the drawing and pressing cavity II is filled with the liquid to reach the optimal fullness, which is the principle of gas prevention.

The liquid fed in from the oil sleeve ring is completely fed in from the oil sleeve ring, and is not the same channel as the liquid pumped up by the tool through the power piston, and the normal oil pump is not provided with a unique channel which is communicated with the inside and the outside and is formed after the functional hole 1.1 is opened, so that the liquid fed in from the oil sleeve ring at the moment improves the fullness, and further improves the pump efficiency, which is the principle of synergy mentioned by the utility model.

As shown in fig. 4, when the power piston 2 moves downwards, the power valve 2.1 is opened, the sealing valve 4 is closed, all the liquid filled in the pulling and pressing cavity ii can enter the lifting cavity i upwards through the channel in the power piston 2 via the power valve 2.1, and when the power piston 2 moves to the lowest position to stop moving, the power valve 2.1 and the sealing valve 4 are closed simultaneously.

As shown in fig. 2, the power piston moves upwards again, enters the next working cycle, repeats the above process, and repeatedly completes the whole oil extraction working process.

As shown in fig. 5, when the well is to be washed and drained, the power piston 2 is only required to be completely lifted out of the working cylinder 1, and at the moment, the hollow parts of the working cylinder 1, the fluid-supplementing filter cylinder 3 and the oil lantern ring outside the fluid-supplementing filter cylinder 3 are in a complete communication state through the functional holes 1.1, the positions of the functional holes 1.1 are vertically communicated and internally and externally communicated, and the bidirectional four-way joint can smoothly complete the well washing and the oil drainage through the outward channels of the functional holes 1.1, which is the well washing and oil drainage principle mentioned by the utility model.
