Abstract
The utility model relates to a metal cotton filtering ring type separator for the oil and sand. The utility model belongs to a filter sand device in the process of the petroleum or the natural gas exploitation. The utility model comprises an inner lining pipe, an outer protection sleeve pipe, and more than two metal cotton filtering rings. The utility model is characterized in that more than two metal cotton filtering rings are arranged between the inner lining pipe and the outer protection sleeve pipe. The high temperature resistance adhesive is coated at a sub-opening of each metal cotton filtering ring. After the high temperature resistance adhesive is solidified at the normal temperature, the high temperature resistance adhesive is jointed into a pipe-shaped whole body. More than two oil passing holes are arranged on the inner lining pipe and the outer protection sleeve pipe. The utility model has good filter sand effect. Because the metal cotton filtering ring forms one integral prefabricated component of stainless steel wires, the metal cotton filtering ring falls off under a well. The utility model has the advantage of long service life.
Description
The utility model relates to the filter sand device in a kind of recover petroleum, the natural gas process.
Down-hole sand control problem must be resolved in the oil field in the process of recover petroleum and natural gas, bad if the sand control problem solves, and then can cause the heavy wear of pumping equipment.In addition, cumulative at the bottom of a large amount of sand deposition into wells, can cause oil well or gas well to stop production, even whole well is scrapped.Present existing sand control filter sieve tube, filtering material is insecure, easily comes off to the down-hole, and strainability is relatively poor.In addition, short application life to the down-hole down, thus improved operating cost.
The purpose of this utility model provides a kind of high temperature resistant, high pressure, good filtration effect, and the metal wool of long service life filters ring type oil-sand eliminator.
Metal wool filters ring type oil-sand eliminator, is made of internal lining pipe, 2 above metal wool filtering rings, oversheath pipes.Internal lining pipe is a seamless steel pipe, and 2 above oil throughs are arranged on the tube wall.The metal wool filtering ring is an a kind of stainless steel wire annular preform, promptly make type by stainless steel wire and high-temperature shaping glue laminated after, make through hot setting and sintering.There is the rim of the mouth junction of metal wool filtering ring.The oversheath pipe is a seamless steel pipe, and 2 above oil throughs are arranged on the oversheath pipe.The oversheath pipe also can be the filament winding pipe.
During assembling, with 2 above metal wool filtering rings, be enclosed within successively on the internal lining pipe, place, the rim of the mouth of per 1 metal wool filtering ring coats high-temperature plastic, and after spontaneous curing, 2 above metal wool filtering rings form an integral filter layer.On the internal lining pipe that is provided with the metal wool filtering ring, put the oversheath pipe.The two ends of oversheath pipe and metal wool filtering ring, with the compactor pressurization, solid welding is connected compactor with the oversheath pipe with internal lining pipe respectively, and reaches air-proof condition.Pipe collar connects with screw thread and internal lining pipe.
Because the metal wool filtering ring is to be clipped between two metal tubes, therefore can not come off.Per 1 metal wool filtering ring all is the stainless steel wire with identical weight, the high-temperature shaping glue of identical weight, after pressing down the type made from equal pressure, makes through hot setting, sintering, and therefore sturdy and durable, filter sand is effective.That the utility model also has is high temperature resistant, high pressure resistant, reduce maintenance capacity and can reduce advantage such as cost for oil production.
Fig. 1 is a structural representation of the present utility model, and Fig. 2 is a filtering ring rigging position schematic diagram, and Fig. 3 is a metal wool filtering ring structural representation.The utility model is described in further detail below in conjunction with accompanying drawing.
Metal wool filters ring type oil-sand eliminator, is made of pipe collar 1, compactor and filter sand device.The filter sand device is made up of internal lining pipe 2,3,60 metal wool filtering ring 4,60 order stainless steel wire meshes 5 of oversheath pipe.Compactor is made up of seal 6 and pressurization part 7.
Internal lining pipe 2 is seamless steel pipes, long 4m, external diameter Φ 140mm, thickness of pipe wall 8mm.400 oil throughs are arranged on the tube wall.Per 1 of 60 metal wool filtering rings 4 is with stainless steel wire and high-temperature shaping glue, after the compression moulding, makes through hot setting and sintering again.Oversheath pipe 3 is a seamless steel pipe, long 3m, and external diameter Φ 182mm, wall thickness 6mm has 510 oil throughs on the oversheath pipe 3.
During assembling, outer bread one deck 60 purpose stainless steel wire meshes 5 at internal lining pipe 2, again with 60 metal wool filtering rings, be enclosed within successively on the internal lining pipe 2, place, rim of the mouth at per 1 metal wool filtering ring scribbles high-temperature plastic, 60 metal wool filtering rings 4 are bonded together, and curing connect into a tubulose integral body at normal temperatures.Put oversheath pipe 3 then.Pressurization part 7 skies are enclosed within on the internal lining pipe 2, and seal 6 is tightened on the pressurization part 7 with screw thread, and seal 6 is connected with 3 solid weldings of oversheath pipe, and reaches air-proof condition.Inwardly screw pressurization part 7 again, at last pressurization part 7 is connected with internal lining pipe 2 solid weldings, and reaches air-proof condition.
During use, needed metal wool is filtered ring type oil-sand eliminator couple together by pipe collar, total length is identical with reservoir depth.Topmost 1 metal wool filters ring type oil-sand eliminator, by pipe collar with client link under the well casing in screw thread and the no oil reservoir.Like this, when starting pumping equipment, sand just can not enter in oil well or the gas well.
