Abstract
The utility model relates to the field of oil field oil extraction, in particular to a novel oil well oil-extracting pipe column. According to the technical scheme, the novel oil well oil-extracting pipe column comprises an oil pipe, an upper connector, a pump cylinder, a valve rod, a plunger, an upper ball valve, a lower ball valve and a fixing valve. The pump cylinder is arranged in the oil pipe, the upper portion of the pump cylinder is connected with the upper connector, the valve rod is connected with the inner portion of the pump cylinder and connected with the plunger, the upper ball valve and the lower ball valve are arranged in the plunger, and the fixing valve is arranged at the bottom of the pump cylinder. The novel oil well oil-extracting pipe column has the advantages of being simple in structure, practical and capable of achieving oil well water injection and effectively improving the oil field oil extraction efficiency.
Description
Technical field
The utility model relates to oil extraction in oil field field, particularly a kind of Novel oil well flow string.
Background technology
The most of oil field of China is all heterogeneous body multiple zone sandstone oil reservoir, all kinds of oil reservoirs have very large otherness in interlayer, plane, by a minute different straticulate exploration, every mouthful of well still has several or tens substratums to exploit, still there is larger difference in the permeability between each layer, these differences have a significant impact waterflooding development effect.Oil field development is according to the difference of exploitation character, generally be divided into producing well and water injection well, well recovery, water injection well is for water filling, function is relatively single, but in actual recovery process, some water injection well possesses the value of produce oil, for the demand to the rational distribution of resources, require producing well and water injection well one well dual-purpose, upper strata water filling, the oil well that lower floor recovers the oil, adopt in the packing of packer single deck tape-recorder, lower floor, just can reach sleeve pipe water filling, the object of oil pipe produce oil, but for the water filling of needs lower floor, the producing well on exploitation upper strata, existing production technique is difficult to meet production requirement.
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 Novel oil well flow string is provided, and simple in structure, practicality, has realized flushing, has effectively improved oil extraction in oil field efficiency.
Its technical scheme is: comprise oil pipe, top connection, pump barrel, valve rod, plunger, upper ball valve, lower ball valve, standing valve, oil pipe inside is provided with pump barrel, the top of described pump barrel connects top connection, the inside of pump barrel connects valve rod, described valve rod connects plunger, plunger inside is provided with upper ball valve and lower ball valve, and the bottom of described pump barrel is provided with standing valve.
Above-mentioned valve rod and the junction of pump barrel are provided with sealing ring.
The beneficial effects of the utility model are: simple in structure, practicality, has realized flushing, has effectively improved oil extraction in oil field efficiency.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model;
In upper figure: oil pipe 1, top connection 2, pump barrel 3, valve rod 4, sealing ring 5, plunger 6, upper ball valve 7, lower ball valve 8, standing valve 9.
The specific embodiment
By reference to the accompanying drawings 1, the utility model will be further described:
The utility model comprises oil pipe 1, top connection 2, pump barrel 3, valve rod 4, plunger 6, upper ball valve 7, lower ball valve 8, standing valve 9, oil pipe 1 inside is provided with pump barrel 3, the top of described pump barrel 3 connects top connection 2, the inside of pump barrel 3 connects valve rod 4, described valve rod 4 connects plunger 6, plunger 6 inside are provided with upper ball valve 7 and lower ball valve 8, and the bottom of described pump barrel 3 is provided with standing valve 9.
Wherein, the junction of valve rod 4 and pump barrel 3 is provided with sealing ring 5.
This apparatus structure is simple, practical, has realized flushing, has effectively improved oil extraction in oil field efficiency.
