Abstract
The utility model relates to a sand filter for the oil, the gas, and the water well, suitable for the underground oil layer section and the water well to prevent the sand. The utility model comprises a stainless steel tube. The utility model is characterized in that the periphery tube walls of the stainless steel tube are respectively provided with a through hole which is filled with the iron or copper powder metallurgy filter material. Both ends of the stainless steel tube is provided with outer screws. The utility model has the advantages of high pressure resistant strength, high tensile strength, and convenient installation and operation. The utility model can be used for the horizontal well to prevent the sand, can be used for the vertical well and the pump to prevent the sand, and can also be used for processing the water purification. When used, the utility model can not be easy to block and can proceed the washing and the backwashing to regenerate, and therefore, the service life is long.
Description
The utility model belongs to a kind of filter plant technical field, and is specifically a kind of in the oil exploitation operation, is used for the micropore antiseptic sand-proof filter of oil well, gas well and deep well sand control in early stage.
The oil-sand isolated by filtration be in the petroleum industry oil producing operation the technical problem that must solve.The filter that is used for well sand control and pump sand control at present mainly contains two kinds: a kind of is to adopt outer wall to twine the filter pipe of stainless steel wire, crude oil filters by the slit, its shortcoming is that cost height (by import), slit are easily stopped up, the distortion of steel wire rapid wear, and can only disposablely use; Another kind is the micro porous filtration oil-sand separator tube that adopts PM technique to manufacture, although this separator tube is a kind of before being better than from structure, cost, but its resistance to compression and tensile strength lower (can only reach desired lower limit), it is unreasonable to have structure, the quality instability, the manufacturing process complexity, the finished product time is long, the deficiency of operational hazards.
The purpose of this utility model provides a kind of oil simple in structure, applied widely, gas, well sand filter.
The purpose of this utility model is achieved in that it includes a stainless steel tube, it is characterized in that being evenly equipped with through hole on the peripheral tube wall of stainless steel tube, is filled with iron or copper powder metallurgy filtering material in through hole, has external screw thread at the two ends of stainless steel tube.
The utility model is owing to be earlier metallurgical powder to be filled in the hole, once sintered success is integrated powder and steel pipe, so resistance to compression and tensile strength height, counter-bending effective, fitting operation is convenient, and this structure both can be used for the horizontal well sand control, also can be used for the well sand control and the pump sand control of peupendicular hole, also can be used for water purification in addition handles, be difficult for stopping up flushable and backwash regeneration, so long service life during use.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the structural representation that partly cuts open of the present utility model.
By shown in Figure 1,1 is stainless steel tube, has external screw thread 2 at the two ends of stainless steel tube, is evenly equipped with the through hole that diameter is 10-20mm on the peripheral tube wall of stainless steel tube, is filled with the filtering material 3 that iron powder is made in through hole.This filtering material by the iron powder metallurgical material and open-work agent, binder and anticorrisive agent mixing after the disposable sintering of sintering electric furnace make.During use, will be above-mentioned several or tens of sand filters are down to the oil layer section of oil, gas and oil down-hole, by be connected in one structure and be fixed on the section of recovering the oil and get final product of nipple.
Claims (2)
1, a kind of oil, gas, well sand filter that is applicable to downhole oil interval and well sand control, it includes a stainless steel tube, it is characterized in that on the peripheral tube wall of stainless steel tube, being evenly equipped with through hole, in through hole, be filled with iron or copper powder metallurgy filtering material, have external screw thread at the two ends of stainless steel tube.
2, oil according to claim 1, gas, well sand filter is characterized in that through-hole aperture is 10-20mm.
