Abstract

The utility model relates to a refractory and high pressure oil sand separator, comprising a seamless steel pipe, a pipe orifice, filter block, filter materials, a multi-hole cover, etc. The interior of the pipe orifice of the seamless steel pipe is filled with filter blocks. The filter block is a basin-shaped metal casing which is provided with filter holes in the bottom part, a metal net and filter materials in the interior, and a multi-hole cover in the top part. The basin-shaped metal casing is provided with a welding post. The filter block is filled in the pipe orifice after the formation, and the welding post is melted through a welder, so the filter block can be firmly welded onto the pipe wall in the pipe orifice. The oil sand separator has the advantages of high temperature resistance, high pressure resistance and high oil exploitation efficiency.

Description

Refractory and high pressure oil sand separator

The utility model relates to a kind of equipment of oil field oil recovery usefulness, a kind of oil-sand strainer that especially a kind of recover petroleum, natural gas are used.

In the past, for the problem of shaking out of oil well, gas well, fail to be well solved in the recovery process of natural gas, oil in the oil field always.Shake out and can cause the heavy wear of pumping equipment, in addition, a large amount of sands are sink to the shaft bottom, can bring difficulty or cause oil well to stop production to exploitation after how amassing, even scrap.We saw the oil-sand eliminator that is drilled with some holes on seamless steel pipe, and this eliminator is to adopt stainless steel wire as filtering material, with the stainless steel wire compacting, sticks with glue then, puts to the hole of seamless pipe tube wall behind the one-tenth piece.Because oil well has certain temperature and certain pressure in the mined bed, this bonding glue is melted, and be extruded the hole of stainless steel tube tube wall.So above-mentioned said oil-sand eliminator is to have shortcoming.

The purpose of this utility model is: provide a kind of strainability stronger, filtering material difficult drop-off, the oil-sand eliminator of high temperature resistant, high pressure.

The utility model is achieved in that several trapezoidal holes on the seamless steel pipe, make a kind of filter block and insert in the interior trapezoidal hole of steel pipe.This filter block has the shell of a peviform, and outer casing bottom has several holes, is affixed on the shell inner bottom part and is placed with wire gauze, and filtering material is arranged on the wire gauze, also has the layer of metal silk screen on the filtering material, and just filtering material is clipped between two wire gauzes.At the upper edge of a peviform shell close-fitting unification perforated lid.Filtering material can adopt powder metallurgy, wire lath, pottery or stainless steel wire.

Provide concrete structure of the present utility model below in conjunction with drawings and Examples:

Accompanying drawing 1 is a schematic diagram of the present utility model.

Accompanying drawing 2 be among the utility model Fig. 1 A-A to schematic diagram.

Accompanying drawing 3 is structural representations of filter block.

Accompanying drawing 4 is bottom schematic view of filter block.

Accompanying drawing 5 is schematic diagrames of wire gauze.

Accompanying drawing 6 is schematic diagrames of perforated lid.

The utility model is made up of seamless steel pipe 1, pore 2, filter block 3, time wire gauze 4, last wire gauze 5, filtering material 6, perforated lid 7, welding column 8 and filter bores 9.Referring to accompanying drawing 1, adopt the seamless steel pipe 1 of 80～400mm, on its tube wall, bore the trapezoidal pore 2 of some 10～40mm, be made into filter block 3 and insert in the pore 2.The structure outside of filter block 3 is metal shells of a peviform, and 9 filter bores 9 are arranged at the bottom of shell, and inner bottom part has following wire gauze 4 and last wire gauze 5, is being filtering material 6 between wire gauze 4 and the last wire gauze 5 down, and filtering material can be used stainless steel wire.Put a slice perforated lid 7 on last wire gauze 5, the filter bores of this perforated lid is identical with the filter bores of outer casing bottom 9, all is 9.Being used for of perforated lid blocked filtering material and the wire gauze in the filter block, in order to avoid come off, perforated lid is a tight fit on the upper edge of peviform shell, 4 welding columns 8 are arranged on the top of peviform shell, when after its filter block is made, inserting pore 2, make the fusing of 4 welding columns with projection welding, in projection welding, give certain pressure, make very firm welded together of the interior tube wall of filter block and seamless pipe pore 2.

The utility model and prior art ratio have high temperature resistant, high pressure resistant, good filtration effect, the filter block advantage such as do not come off.

Claims

1, a kind of oil-sand eliminator, comprise seamless steel pipe, pore, it is characterized in that being filled with filter block in the plurality of tube holes on the tube wall of said seamless steel pipe, this filter block has the shell of a peviform, outer casing bottom has several filter bores, be placed with upper and lower two wire gauzes in the shell, in the middle of two wire gauzes filtering material arranged, one and the friction tight perforated lid in peviform shell upper edge are arranged above the last wire.

2, oil-sand eliminator according to claim 1, but it is characterized in that said filtering material powder metallurgy, wire lath, pottery or stainless steel wire.
