Abstract
The utility model relates to a balanced air-controlled, blockage-removal and oil-production-increasing device, which mainly solves the problems in the prior art that existing negative-pressure oil exploiting equipment is higher in cost and difficult in popularization due to the necessary string-pulling operation. The balanced air-controlled, blockage-removal and oil-production-increasing device is characterized in that a host (4) is internally provided with a piston and the upper part of the piston is connected with a piston rod (2). The piston rod (2) is fixed onto the walking beam of a pumping unit through a fixed clamping plate (1). The bottom of the host (4) is respectively connected with an air inlet pipe (7) and an air exhaust pipe (6). The other end of the air inlet pipe (7) is connected with a casing valve at a wellhead, while the other end of the air exhaust pipe (6) is connected with a tubing valve at the wellhead. The air inlet pipe (7) and the air exhaust pipe (6) are respectively provided with a one-way valve (8) and a check valve (9). According to the technical scheme of the utility model, due to the adoption of the balanced air-controlled, blockage-removal and oil-production-increasing device, a negative pressure can be applied onto a casing annulus, while the production of oil is increased. The balanced air-controlled, blockage-removal and oil-production-increasing device is convenient in installation and can be used repeatedly.
Description
Technical field
The utility model relates to the field, oil field, is that the de-plugging of a kind of balance control gas increases oily device specifically.
Background technology
Negative pressure production be present effect preferably a physics increase oil tech, obtained good effect, but adopt this Technology Need to move the tubing string job execution at present, cost is higher, also had a strong impact on the popularization of this technology, for this reason, on the basis of motionless operation oil well being carried out the negative pressure de-plugging, is urgent problem.
Summary of the invention
Need move the deficiency that tubing string operation, cost are higher, be difficult to promote in order to overcome existing negative pressure extracting device of oil, the utility model provides the de-plugging of a kind of balance control gas to increase oily device, this balance control gas de-plugging increases oily device and can produce suction function to the oil jacket annular space, have oil increasing effect, and cost is low, easy for installation, reusable.
The technical solution of the utility model is: the de-plugging of a kind of balance control gas increases oily device, comprise main frame, main frame is fixed on the oil pumper support by bracing frame, described main frame is built-in with piston, piston top is connected with piston rod, piston rod is fixed on the oil pumper walking beam by strap, the main frame bottom is connected with air inlet pipe and stack respectively, the other end of air inlet pipe connects the well head sleeve gate, the other end of stack connects well head oil pipe gate, and is respectively equipped with one way valve and flap valve on air inlet pipe and the stack.
The utlity model has following beneficial effect: owing to take such scheme, piston in the main frame is connected on the oil pumper walking beam by piston rod, and link to each other with the well head production tree by air inlet and exhaust piper, when walking beam moves up and down, make the natural gas in the downhole oil cover annular space be drawn into cylinder body of host machine inside, and discharge and enter production flow line, increase liquid, oil increasing effect thereby played, thereby increased output, improved production efficiency.And this device is easy for installation, in that a bite is aboveground when losing oil increasing effect, it can be pulled down, and is installed to that other are aboveground, makes it continue the effect that performance increases oil.
Description of drawings
Fig. 1 is structural representation of the present utility model.
1-strap among the figure, 2-piston rod, 3-spiracle, 4-main frame, 5-bracing frame, 6-stack, 7-air inlet pipe, 8-one way valve, 9-flap valve.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
By shown in Figure 1, the de-plugging of a kind of balance control gas increases oily device, comprise main frame 4, main frame 4 is fixed on the oil pumper support by bracing frame 5, and described main frame 4 is the piston rod structure, and inside is equipped with piston, piston top is connected with piston rod 2, piston rod 2 is fixed on the oil pumper walking beam by strap 1, when the oil pumper walking beam moves up and down, can drive piston up-down.Main frame 4 upper portion side wall are provided with several spiracles 3, too high to prevent the cylinder body upper pressure, and main frame 4 bottoms are connected with air inlet pipe 7 and stack 6 respectively, the other end of air inlet pipe 7 connects the well head sleeve gate, the other end of stack 6 connects well head oil pipe gate, and is respectively equipped with one way valve 8 and flap valve 9 on air inlet pipe 7 and the stack 6.Safety valve is installed in air inlet pipe 7 and stack 6 bottoms, when the pipeline internal pressure is too high, carries out pressure release, avoids causing the accident.
This device utilizes the running of oil pumper equipment that power resources are provided, and transmits by means of the oil pumper walking beam.When the oil pumper upstroke is moved, walking beam drives piston rod 2 pulling pistons and moves upward, abdicate certain space in the cylinder body of host machine and form negative pressure, make the natural gas of oil well oil jacket annular space suck cylinder interior, when the oil pumper down stroke, walking beam drives piston rod 2 pulling pistons and moves downward, and natural gas in the cylinder body is discharged, and enters production flow line.Adopt this device, can produce suction function to the oil jacket annular space, and have good liquid, the oil increasing effect of increasing, thereby increased output, improved production efficiency.
This device is applicable to following situation: 1, the well head sleeve pipe is intact does not leak, and can produce the oil well of negative pressure; 2, the producing zone position is more, has the oil well of certain interlayer; 3, stratum energy remains intact, and the oil well of follow-up energy supplement is arranged; 4, low yield liquid measure, low moisture, the production fluid amount is not more than 20 tons, is not less than 8 tons, has certain oil well that stops up.And this device can be reused, when this device in that a bite is aboveground when losing oil increasing effect, it can be pulled down, be installed to that other are aboveground, make it continue the effect that performance control cover increases oil.
