Abstract
The utility model provides a sintered stainless steel wire netting screen used for underground sand prevention and sand screening in heavy oil recovery of oil field, which consists of an upper joint, sintered stainless steel wire netting slotted liner bodies 2 and a lower joint 3. Three through seven stainless steel nets and stainless steel powder are sintered into 20% through 40% filter plates having certain strength and adjustable porosity. The filter plates are rolled into the sintered stainless steel wire netting slotted liners 2 of designed specification. The upper joint 1, the sintered stainless steel wire netting slotted liner bodies 2 and the lower joint 3 are all connected through thread. The utility model solves the problems of prior art that pipe slots enlarge easily, wear easily; pores enlarge easily; area of passage of metal wool sand screening clasp slotted liners is small, and clasps drop easily. The utility model can be widely applied for underground sand prevention and sand screening in heavy oil recovery of oil field.
Description
Technical field:
The utility model relates to the sintered stainless steel wire lath sand screen that down-hole sand control filter sand is used in a kind of oil-field thick-oil exploitation.
Background technology:
Adopt of sand control sand screen of often using in the present domestic oil-field thick-oil exploitation isolated sand control, sand screen more, and the problem that this sand control, sand screen exist is that seam is variable big, easy to wear, and then hole is variable big; Adopt the cotton filter sand button of stainless steel metal screen casing, this screen casing area of passage is little, easily falls button.
The utility model content:
The utility model purpose is to provide a kind of sintered stainless steel wire lath sand screen, and it is big, easy to wear that this sand screen has solved the slot pipe seam mutability that exists in the prior art, and hole is variable big; Metal wool filter sand button screen casing area of passage problem little, that easily fall to detain.
The technical scheme that its technical problem that solves the utility model adopts is: 3-7 layer stainless (steel) wire and stainless steel powder sintering are made the filter plate with certain intensity and the adjustable 20-40% of degree of porosity, make the box and pin screw thread through sintered stainless steel wire lath screen casing body, body two of rolling into design specifications.This sintered stainless steel wire lath sand screen is made up of top connection, sintered stainless steel wire lath screen casing body, lower contact, and top connection is with lower contact with sintered stainless steel wire lath screen casing body and is threaded.This sintered stainless steel wire lath sand screen has that seepage area is big, intensity is high, antiacid corrosion-resistant, be difficult for stopping up.
The new beneficial effect of this practicality is, and is simple in structure, in light weight, be convenient to install, change, has big, the difficult obstruction of seepage area, the intensity height, antiacid corrosion resistant characteristics, bending when this pipe uses under oil well, extruding, rotation or on propose distortion and still can be kept perfectly and the high osmosis energy.
Description of drawings:
Accompanying drawing is the utility model overall structure schematic diagram.
Among the figure, 1, top connection, 2, sintered stainless steel wire lath screen casing body, 3, lower contact.
The specific embodiment:
As shown in the figure, 3-7 layer stainless (steel) wire and stainless steel powder sintering are made the filter plate with certain intensity and the adjustable 20-40% of degree of porosity, through rolling into the sintered stainless steel wire lath screen casing body 2 of design specifications, the box and pin screw thread is made at body two.This sintered stainless steel wire lath sand screen is made up of top connection 1, sintered stainless steel wire lath screen casing body 2, lower contact 3, and top connection 1 and sintered stainless steel wire lath screen casing body 2 are with lower contact and are threaded.
