Abstract
A sand screening pipe device with a trapezoidal toothed stainless steel plate mesh cylinder belongs to the technical field of oilfield equipment and comprises a central pipe, seal head hoops, a longitudinal and latitudinal steel mesh, the trapezoidal toothed stainless steel plate mesh cylinder and a protective cover mesh cylinder. The longitudinal and latitudinal steel mesh is fixedly connected to the periphery close to the middle of the central pipe, the trapezoidal toothed stainless steel plate mesh cylinder is sleeved on the periphery of the longitudinal and latitudinal steel mesh on the central pipe in a penetrating manner, the protective cover mesh cylinder is sleeved on the periphery of the trapezoidal toothed stainless steel plate mesh cylinder in a penetrating manner, two ends of the central pipe are inwardly sleeved in inner holes in a penetrating manner along the direction of pits of the seal head hoops, the pits of the seal head hoops are fastened at two tips of the trapezoidal toothed stainless steel plate mesh cylinder and at two tips of the protective cover mesh cylinder, and the seal head hoops are fixedly connected to positions close to the two ends of the central pipe. The sand screening pipe device with a smooth surface is resistant to rust and high temperature and high in compressive strength, oil permeability is doubled, oil production is increased, and operation time is prolonged.
Description
Technical field: stepped tooth stainless steel plate mesh tube sand filtering tube device is the device in the technical field that belongs in the oil field equipment.
Background technology: known, at present the oil field in the process of oil pumping, the one, well casing lower end oil contains sand, the periphery that oil pipe is drilled to pore in the lower end is curling screen cloth, tightly wraps screen cloth fixed with steel wire; The 2nd, with utility model patent---the gear shape stainless steel plate mesh tube sand filtering tube device of the patent No. 200520143412.7 applications, their shortcoming is: in oil pumping process, oil is difficult to do in the periphery of oil pipe the motion of circumferencial direction; More than two kinds filter petroleum pipeline is peripheral, exist oil between the peripheral dead band of flowing of oil pipe, this is the difficult problem in the oil pumping filter sand.
Summary of the invention: for solving the difficult problem in the background technology; The object of the invention provides a kind of stepped tooth stainless (steel) wire tube sand filtering tube device; The central tube two ends of this device are provided with screw thread; The mid-length of central tube and vicinity are provided with several through holes, and at outside fixed the longitude and latitude steel mesh of central tube, the outside of longitude and latitude steel mesh is wearing stepped tooth stainless steel plate mesh tube; The outside of stainless steel plate mesh tube is wearing guard shield net tube, with the end socket hoop with guard shield net tube and stepped tooth stainless steel plate mesh tube closed at both ends in vicinity, central tube two ends; Stepped tooth stainless steel plate mesh tube, non-corrosive can freely-movable in the gap of oil between the peripheral graticules of central tube, and the oil impregnate flowing space does not have the dead band, and oil impregnate efficient obviously improves, and the oil pumping activity duration prolongs, and improves oil production, increases the business economic benefit.
The technical scheme that this device adopted is: stepped tooth stainless steel plate mesh tube sand filtering tube device; Formed with central tube, end socket hoop, longitude and latitude steel mesh, stepped tooth stainless steel plate mesh tube and guard shield net tube; It is characterized in that: central tube is a round steel pipe; The two ends of round steel pipe are provided with screw thread, and the centre of round steel pipe and vicinity thereof are provided with several through holes; The end socket hoop is an annular steel body, and a through hole is established at the center of annular steel body, in the interior side of annular steel body spill circle nest is being set, and one side is provided with splay conically shaped body in the outside of annular steel body; The longitude and latitude steel mesh is a steel wire track and column braiding net; Stepped tooth stainless steel plate mesh tube is the trapezoidal teeth stainless steel plate mesh tube that thin stainless steel plate mesh is processed, and the expanded metals in several micro rectangle holes of processing with thin corrosion resistant plate is claimed stainless steel plate mesh; Guard shield net tube is the steel mesh of the quadrangle mesh that is drawn into steel plate, and steel mesh is rolled into the net tube, and is fixed in net tube joint; The assembling of this device: curl in the middle of the central tube and vicinity peripheral fixed with the longitude and latitude steel mesh, be set on the periphery of the longitude and latitude steel mesh on the central tube with stepped tooth stainless steel plate mesh tube; Be set on the periphery of stepped tooth stainless steel plate mesh tube with guard shield net tube; Respectively in the endoporus with the spill nest direction of end socket hoop, wearing from the inward at both ends of central tube, the spill nest of end socket hoop is fastened on stepped tooth stainless steel plate mesh tube and the guard shield net tube two ends, and the end socket hoop is cemented in the vicinity, two ends of central tube.
Owing to adopt the advantage of above technical scheme to be: utilize stepped tooth stainless steel plate mesh tube sand filtering tube device, be installed in the pumpingh well lower end, the control sand grains enters into the stepped tooth stainless steel plate mesh tube sand filtering tube device in the oil well pipe; Have smooth surface, non-corrosive, high temperature resistant; Compressive strength is big, and the oil permeability has increased twice, increases oil production; Prolong the oil pumping activity duration, improve the business economic benefit.
