Abstract
The utility model provides a fluid pressure type sliding sleeve bleeder, includes: top connection (1), steel ball (2), upper seal circle (3), lower seal circle (4), pin (5), sliding sleeve (6), outer tube (7), lower clutch (8), characterized by: fluid pressure type sliding sleeve bleeder for pipe form, from bottom to top lower clutch (8) in proper order with outer tube (7), top connection (1) threaded connection, be equipped with drain tap (X) in the upper portion symmetry of outer tube (7), be equipped with sliding sleeve (6) in centre bore (Z) internal drainage mouth (X) position, the top of sliding sleeve (6) is equipped with steel ball (2), the symmetry is equipped with pin (5) between upper portion sliding sleeve (6) and outer tube (7) of drain tap (X). The utility model discloses a being applicable to and installing on well measure and regulate tubular column, after measure and regulate accomplishes, suppress through the bowling, open the draining hole and realize measure and regulate tubular column draining, crude oil is not excessive when having guaranteed the tubular column, prevents environmental pollution, and the environmental protection lightens workman's intensity of labour.
Description
Technical field
This utility model relates to water injection well in oil fields downhole tool, specifically a kind of fluid pressure type sliding sleeve tubing drain.
Background technology
The layering of Gudao area of Shengli Oilfield oil recovery factory is surveyed and is adjusted tubing string mainly based on one-level two sections and two grades three sections, the down-hole of employing
Instrument is mainly reducer class and K344 hydraulic expansion envelope, and bottommost oil reservoir uses common reducer, and top oil reservoir uses sliding sleeve
Reducer.Sliding sleeve throttling device is by pitching sealed lower portion tubing string, and waterpower is suppressed and destroyed by sliding sleeve, is formed the same with common reducer
The reducer of function.Along with progression increases, every grade of sphere diameter is the most different, and the most up the diameter of ball is the biggest, typically from upper
A diameter of under to: Φ 45mm, Φ 40mm, Φ 35mm.This tubular column structure has the disadvantage that after survey tune completes and plays operation
During tubing string, because whole tubing string is in air-tight state, it is impossible to realize drainage, can make well head lift pipe string difficulty, overflow is serious, and can make
Become serious environmental pollution.The drainage device on this tubing string is applied mainly to have two kinds at present, i.e. self-rotary bleeder and draining
Tubing anchor.But both apparatus structures are complicated, costly, usability can be repaired poor.
Summary of the invention
The purpose of this utility model is aiming at above-mentioned weak point, it is provided that a kind of fluid pressure type sliding sleeve tubing drain.
The purpose of this utility model is realized by following technical proposals:
This utility model includes: top connection, steel ball, upper sealing ring, lower seal, pin, sliding sleeve, outer tube, lower contact；Institute
The fluid pressure type sliding sleeve tubing drain stated is circular tube shaped, and lower contact from bottom to top is threadeded with outer tube, top connection successively, at outer tube
Top is arranged with drain tap, is provided with sliding sleeve in centre bore internal drainage mouth position, and the top of sliding sleeve is provided with steel ball, at drain tap
It is arranged with pin between top sliding sleeve and outer tube.
Top connection in above-mentioned fluid pressure type sliding sleeve tubing drain is provided with female thread.
Lower contact in above-mentioned fluid pressure type sliding sleeve tubing drain is provided with external screw thread.
Sliding sleeve in above-mentioned fluid pressure type sliding sleeve tubing drain is respectively arranged at two ends with twice cannelure up and down, fills respectively in cannelure
There are upper sealing ring and lower seal.
The beneficial effects of the utility model are: be suitably mounted to well and survey on tune tubing string, after survey tune completes, by throwing
Ball is suppressed, and opens oil leak hole and realizes surveying tune pipe column oil drainage, it is ensured that during lift pipe string, crude oil is the most excessive, prevents the pollution of the environment, protection ring
Border, alleviates the labor intensity of workman.
Accompanying drawing explanation
Fig. 1-this utility model master is depending on partly cuing open structural representation.
In figure, 1. top connection, 2. steel ball, 3. go up sealing ring, 4. lower seal, 5. pin, 6. sliding sleeve, 7. outer tube, 8.
Lower contact；X. drain tap, Z. centre bore.
Detailed description of the invention
In conjunction with accompanying drawing, the utility model will be further described:
Embodiment one
Fluid pressure type sliding sleeve tubing drain is by top connection 1, steel ball 2, upper sealing ring 3, lower seal 4, pin 5, sliding sleeve 6, outer tube
7, lower contact 8 forms.Described fluid pressure type sliding sleeve tubing drain is circular tube shaped, be provided with from bottom to top external screw thread lower contact 8 successively with
Outer tube 7 and to be provided with female thread top connection 1 threaded, is arranged with drain tap X on the top of outer tube 7, at centre bore Z internal drainage
Mouth X position is provided with sliding sleeve 6, and the top of sliding sleeve 6 is provided with steel ball 2, and sliding sleeve about 6 is respectively arranged at two ends with twice cannelure, cannelure
Inside it is respectively provided with sealing ring 3 and lower seal 4, between the top sliding sleeve 6 and outer tube 7 of drain tap X, is arranged with pin 5.
Embodiment two
Operational approach: first, is arranged on the top going up most a sliding sleeve throttling device, with therebetween by fluid pressure type sliding sleeve tubing drain
Every requiring 5～10m, and the minimum diameter of bleeder should be greater than the diameter of topmost sliding sleeve throttling device steel ball, typically should be greater than 3～
6mm, to ensure that steel ball 2 passes through bleeder；Secondly, after survey tune completes, put into steel ball 2, be sitting in the top of sliding sleeve 6, make
Sliding sleeve about 6 separates, and suppresses with water filling mains water power, makes sliding sleeve about 6 form pressure reduction, produces axial force, cut off shear pin
5, sliding sleeve 6 moves down, and drain tap X exposes, it is achieved draining, reaches to ensure that during lift pipe string, crude oil is the most excessive, prevents the pollution of the environment, protection
The purpose of environment.
