Abstract
The utility model relates to a stainless steel plate net type sieve tube for a filtering device of the oil extraction and the sand prevention of an oil field, which can be also used for filtering gas and liquid in the technical field of chemical industry, water supply, etc. The utility model is composed of a tube hoop, an outer tube, a stainless steel sand-proof plate net tube, a base tube, and a steady apparatus, wherein, the interior of the stainless steel sand-proof plate net tube is provided with the base tube, and the exterior of the stainless steel sand-proof plate net tube is provided with the outer tube; the tube walls of the base tube and the outer tube are provided with circular pore spaces capable of being arrayed in an equidistant and stagger mode, and the interior of the outer tube is provided with the steady apparatus. The utility model has the advantages of uniform pore spaces, high intensity, strong corrosion resistance, large filtering area, favorable seepage performance, long service life, etc., and can improve the yield and the quality of the oil extraction.
Description
The utility model relates to a kind of filtration facility-stainless steel plate mesh formula screen casing that is used for oil field oil recovery sand control, also can be used for gas, the liquid filtering in fields such as chemical industry, feedwater.
At present, the filtration facility that domestic oil field oil recovery fat sand mainly adopts is the spun yarn net that lays the braiding of 1-3 layer Stainless Steel Wire on the inside and outside tube wall of flow string, and its interface is outer to be welded by scolding tin, and the space in the middle of the inner and outer pipes adopts carborundum to fill and centralizer is managed admittedly.The filter screen of this production facilities very easily damages in the down-hole oil production operation of high temperature, high pressure, has that life cycle is short, waste is big, dismounting is difficult, labor strength is high, causes the poor effect of recovering the oil.Another kind is a boxing stainless steel screen casing, and screen drum is that the Stainless Steel Wire boxing with special cross-section forms, and is aided with parent tube and centralizer in screen drum, because the steel wire of screen drum is exposed to the outside, directly there is the deficiency of aspects such as anti-collapsing force, oil recovery seepage flow in the contact layer of sand, and the cost height, costs an arm and a leg.
The purpose of this utility model is for improving the backward technology of oil field oil recovery sand control, improve oil production rate and quality, a kind of good reliability, good, the long service life of sand controlling result are provided, can reduce the special-purpose equipment-stainless steel expanded metals formula screen casing of the oil recovery sand control of cost for oil production.
The utility model stainless steel plate mesh formula screen casing content Description:
The utility model stainless steel plate mesh formula screen casing is characterized in that: be made up of pipe collar, outer tube, stainless steel sand control expanded metals pipe, parent tube, firm device; Stainless steel sand control expanded metals pipe is by the thick corrosion resistant plate of 0.3-0.7mm, staggered uniform rectangular hole is arranged on the plate face, the length of hole is that 4.5-10mm, width are 0.1-3mm, pitch-row in the direction all around of hole is 1.5-5mm, by rolling up the letter welding in a tubular form, at the built-in parent tube of stainless steel sand control expanded metals pipe, an external outer tube, have equidistant staggered circular holes on the tube wall of parent tube and outer tube, pore diameter is 8-15mm, head is provided with outside thread at the two ends of outer tube, and pipe collar links together two outer tubes by screw thread; Internal thread is set in the two ends of outer tube connects firm device, firm device is one to have externally threaded tubular body, has at 3 uniform fixed holes of circumferencial direction 120 degree in two end faces; Stainless steel plate mesh formula screen casing can adopt individual layer stainless steel sand control expanded metals pipe and two kinds of forms of double-layer stainless steel sand control expanded metals pipe.
Characteristics such as that the utility model stainless steel plate mesh formula screen casing has is rational in infrastructure, porous nickel, intensity height, corrosion resistance is strong, filter area is big, the seepage flow performance is good, sand control tight, long service life, replacing are easy, easy to use can improve the output and the quality of oil recovery greatly.
Embodiment
