Abstract
The utility model relates to oil production equipment, in particular to a device for sand-control separate-zone oil production of an oil well. According to the technical scheme, the device for sand-control separate-zone oil production of the oil well comprises an oil pipe, a sleeve, a safety control valve, multiple sets of layered sealers, sand-control dividers, sand-control screens and a guider, wherein the sleeve is fixed to the outer side of the oil pipe, the safety control valve is arranged on the upper portion of the oil pipe, the multiple sets of layered sealers are arranged on the oil pipe, each sand-control divider is arranged between the corresponding layered sealer and the sleeve, each sand-control screen is arranged outside the portion, between the corresponding two adjacent layered sealers, of the oil pipe, and the guider is connected to the tail end of the oil pipe. The device for sand-control separate-zone oil production of the oil well has the advantages that separate-zone oil production is achieved, the structure of an oil production pipe column is simple, the operability is high, sand-control oil production can be effectively achieved through the sand-control screens, and the oil production quality is improved.
Description
Technical field
The utility model relates to a kind of oil production equipment, particularly a kind of sand control layering pumping unit.
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, because causing down-hole sand content, water filling increases, cause production fluid sand content to increase, affect oil recovery quality.
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 sand control layering pumping unit is provided.
Its technical scheme is: comprise oil pipe, sleeve pipe, Safety control valve, layering sealer, sand control dispenser, sand control screen, guider, oil pipe external stability sleeve pipe, Safety control valve is installed on the top of oil pipe, described oil pipe is provided with multicomponent layer sealer, wherein between each layering sealer and sleeve pipe, be provided with sand control dispenser, oil pipe outside between each layering sealer is provided with sand control screen, and the end of oil pipe connects guider.
Above-mentioned sand control screen comprises box cupling, base tube, filtration members, and the two ends of described base tube are threaded connection respectively box cupling, and described base tube is provided with many group filtration members.
Above-mentioned filtration members comprises filter and mistake filter ruffle, and the outside of filtration members was provided with filter ruffle, vertical distribution filter in filtration members.
The beneficial effects of the utility model are: realize oil production by layer, flow string is simple in structure, workable, and sand control screen can effectively be realized oil extraction sand prevention, improve oil recovery quality.
