Abstract
The utility model relates to an oilfield injection-production device, in particular to a hydraulic feedback injection-production device. The hydraulic feedback injection-production device comprises an oil pipe, an oil sucker rod, a big pump cylinder, a big plunger, a small plunger and a small pump cylinder, wherein the oil sucker rod is arranged in the oil pipe, the lower portion of the oil pipe is connected with the big pump cylinder, the lower portion of the big pump cylinder is connected with the small pump cylinder, the big plunger is arranged in the big pump cylinder, the small plunger is arranged in the small pump cylinder, the oil sucker rod is respectively connected with the big and the small plungers, the small plunger is connected with a sand drain pipe, a ring cavity is arranged outer the sand drain pipe, and a sand drain hole is arranged on the ring cavity. The hydraulic feedback injection-production device has the beneficial effects that the big plunger enters the oil pipe arranged on the big pump cylinder by upwardly lifting an oil sucker rod column, the small plunger enters the big pump cylinder to form a gas injection channel and form gas injection operation, the big plunger enters the big pump cylinder by downwardly placing the oil sucker rod column, and the small plunger enters the small pump cylinder to close the gas injection channel and complete oil production actions, thereby improving oil production efficiency.
Description
Technical field
The utility model relates to a kind of oil field injection and extraction equipment, particularly a kind of hydraulic feedback injection-recovery apparatus.
Background technology
Oil field enters the later development stage, and the mode of adopting by note is recovered the oil, and it is large that current conventional note is adopted equipment energy consumption, oil production is little, can not obtain in time shaft bottom operation situation, because oil well sand content is large, the problem that there will be pumping unit to stop up, causes operating efficiency low, affects oil field and normally exploits.
Summary of the invention
The purpose of this utility model is exactly in view of the foregoing defects the prior art has, and a kind of hydraulic feedback injection-recovery apparatus is provided.
Its technical scheme is: comprise oil pipe, sucker rod, large pump barrel, large plunger, small plunger, little pump barrel, oil pipe inside is provided with sucker rod, oil pipe bottom connects large pump barrel, large pump barrel bottom connects little pump barrel, and described large pump barrel inside is provided with large plunger, and little pump barrel inside is provided with small plunger, sucker rod connects respectively large plunger and small plunger, described small plunger connects lets out sandpipe, and the described outside of letting out sandpipe is provided with ring cavity, and described ring cavity is provided with clearance hole.
The above-mentioned sandpipe tube wall of letting out is provided with some oil extraction apertures.
The beneficial effects of the utility model are: by carry rod string, huge pillar enters oil pipe on large pump barrel, small plunger enters large pump barrel, forms steam injection passage, realizes steam injection operation, transfer rod string, huge pillar enters large pump barrel, and small plunger enters little pump barrel, closes steam injection passage, complete the action of recovering the oil, improved oil recovery efficiency.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model;
In upper figure: oil pipe 1, sucker rod 2, large pump barrel 3, large plunger 4, small plunger 5, little pump barrel 6, let out sandpipe 7;
Accompanying drawing 2 is structural representations of the present utility model;
In upper figure: ring cavity 7.1, clearance hole 7.2, oil extraction aperture 7.3.
The specific embodiment
1-2 by reference to the accompanying drawings, the utility model will be further described:
The utility model comprises oil pipe 1, sucker rod 2, large pump barrel 3, large plunger 4, small plunger 5, little pump barrel 6, oil pipe 1 inside is provided with sucker rod 2, oil pipe 1 bottom connects large pump barrel 3, large pump barrel 3 bottoms connect little pump barrel 6, described large pump barrel 3 inside are provided with large plunger 4, little pump barrel 6 inside are provided with small plunger 5, sucker rod 2 connects respectively large plunger 4 and small plunger 5, described small plunger 5 connects lets out sandpipe 7, the described outside of letting out sandpipe 7 is provided with ring cavity 7.1, described ring cavity 7.1 is provided with clearance hole 7.2, the outside of letting out sandpipe 7 is provided with ring cavity 7.1 and can realizes sand setting collection, then discharge by clearance hole 7.2.
Above-mentioned sandpipe 7 tube walls of letting out are provided with some oil extraction apertures 7.3.
When gas injection, above carry sucker rod, huge pillar enters oil pipe on large pump barrel, small plunger enters large pump barrel, forms steam injection passage, steam injection, when oil pumping, transfer rod string, huge pillar enters large pump barrel, and small plunger enters little pump barrel, close steam injection passage, open and take out, in oil recovery process, let out sandpipe and can reduce the sand content of Produced Liquid, reduce oil recovery sand content.
