Description
Technical field
The utility model relates to a kind of sand control installation, particularly a kind of flow string sand control installation.
Background technology
In the process of oil field development, the pollution of various impurity to oil reservoir, fouling and the wax deposition etc. on stratum itself that cause due to the reason such as drilling well, pressure break, often make reservoir permeability reduce, oil well output is declined, for low-porosity hyposmosis or ultra-low penetration rock stratum, production declining is even more serious especially.Crude oil is at down-hole thickness, causes down-hole to stop up, and conventional method is oil well acidation to be removed to these stop up, but can bring secondary pollution to oil reservoir again when de-plugging in this way.
Chinese patent literature number is: CN 102913211 A, patent name is: " sand control screen, formed by multilayer tubular structures, multilayer tubular structures is followed successively by guard shield layer from outside to inside, sand screen stratum reticulare, gravel packing zone and cutting seam sieve tube layer, described sand screen stratum reticulare is the inflatable sand screen stratum reticulare of outer rolling; This device arranges sand control screen cloth by physics sand control, causes unavoidably the obstruction of the grains of sand in oil recovery process, and sand control filter screen easily causes sand blocking plug mesh in the course of the work, affects oil recovery efficiency.
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 flow string sand control installation is provided.
Its technical scheme is: comprise sleeve pipe, oil pipe, safety joint, hydraulic anchor, motor, rotation sand control device, centralizer, guider, inside pipe casing is installed oil pipe, oil pipe connects hydraulic anchor by safety joint, the inside standing screw pump of oil pipe, described screw pump connects rotation sand control device, the afterbody of oil pipe connects guider, described guider is fixed by centralizer, the inside of described guider is provided with spirally-guided impeller, rotation sand control device comprises fixed disk, rotating disc, claw, between fixed disk and rotating disc, be provided with ball, rotating disc is provided with claw, on rotating disc, fix sand control screens by claw.
Above-mentioned fixed disk is provided with card article, and the interior shoulder of top connection is provided with the draw-in groove matching with the card article on fixed disk.
The beneficial effects of the utility model are: oil extraction sand prevention is effective, simple in structure, have improved oil recovery efficiency, fixed disk on rotating mechanism, rotating disc relative motion, realize the rotation of sand control screens, and the grains of sand that stick together in sand control screens are screened out, alleviate the sand content of fluid, improved the quality of fluid.
