Abstract
The utility model relates to an anticorrosive, antiscaling and antirust working cylinder for a water distributor used for a pipe column of the field of oilfield water filling. The utility model solves the easily ineffective problem of the pipe column of a water distributor. The utility model is characterized in that the inner wall of a main body (1) is provided with a groove for arranging and fixing a lining (2). The utility model can avoid that a test via hole is broken or clogged by the corrosion production of alkali acid ion and the precipitated scale in the process of water filling; the water filling pipe column can not fail; the reworking can be reduced; the labor strength can be reduced.
Description
Technical field:
The utility model relates to the used a kind of seating nipple of a kind of oil-field flooding field tubing string, belongs to anti-corrosion anti-scale rust-proof type injection well downhole flow regulator seating nipple.
Background technology:
Tubing string used injection well downhole flow regulator in oil-field flooding field all uses seating nipple at present, in order to realize the effects such as test shutoff of water injection well.And existing seating nipple is because its test through hole is generally chromium plating, in water injection well in the course of work, can't resist the corrosion of the alkali acid ion that injects water, the accumulation incrustation scale destroys, can't finish test and cause injection well downhole flow regulator to test through-hole surfaces easily, cause whole water injection string to lose efficacy, loss is big, the rework rate height, and labour intensity is big.
The utility model content:
In order to overcome the deficiency that existing injection well downhole flow regulator tubing string lost efficacy easily, the utility model provides a kind of anti-corrosion anti-scale rust-proof type injection well downhole flow regulator seating nipple, and the test through hole of this seating nipple is the accumulation incrustation scale not, is unlikely the injection well downhole flow regulator tubing string and loses efficacy.
The technical scheme that its technical problem that solves the utility model adopts is: this injection well downhole flow regulator seating nipple, comprise injection well downhole flow regulator seating nipple main body, and it is built-in fixing by lining that main body inner wall has groove.
Above-mentioned lining is embedded in the main body inner wall groove, and lining is a non-metallic material.
The beneficial effects of the utility model: because this injection well downhole flow regulator seating nipple has groove in main body inner wall, and be inlaid with anti-corrosion anti-scale rust-proof type non-metallic bushings, avoid the corrosion generation and the precipitated scale of alkali acid ion in the injecting process to destroy or stop up the test through hole, thereby water injection string was lost efficacy, reduced and done over again, greatly reduced labour intensity.
Description of drawings:
Fig. 1 is a structure sectional view of the present utility model.
The specific embodiment:
Below in conjunction with accompanying drawing the utility model is further described:
In conjunction with the accompanying drawings 1, this injection well downhole flow regulator seating nipple comprises injection well downhole flow regulator seating nipple main body 1, have groove at main body 1 inwall, it is built-in fixing to be used for lining 2, is about to anti-corrosion anti-scale rust-proof type non-metallic material lining 2 and is embedded on main body 1 inboard wall groove, play the antirust effect of anti-corrosion anti-scale, avoid the corrosion generation of alkali acid ion in the injecting process and precipitated scale and destroy or stop up the test through hole, thereby water injection string was lost efficacy, reduced and done over again, greatly reduce labour intensity, be fit to promote.
Claims (3)
1, the used anti-corrosion anti-scale rust-proof type injection well downhole flow regulator seating nipple of a kind of oil-field flooding field tubing string comprises injection well downhole flow regulator seating nipple main body (1), it is characterized in that: it is built-in fixing by lining (2) that main body (1) inwall has groove.
2, anti-corrosion anti-scale rust-proof type injection well downhole flow regulator seating nipple according to claim 1 is characterized in that: lining (2) is embedded in main body (1) inboard wall groove.
3, anti-corrosion anti-scale rust-proof type injection well downhole flow regulator seating nipple according to claim 1, it is characterized in that: lining (2) is a non-metallic material.
