Description
Technical field
The utility model belongs to oil field development production technical field, especially a kind of non-sand control open hole well injection self-advancing type
Multiple-limb slim hole completion tool.
Background technique
Production oil field in inefficient well, shut down well have become restrict oilfield stable production key factor.It is low for low yield liquid class
Inefficient well is produced, poor if it is stratum fluid supply capacity caused by due to geology itself, development plan should just increase oil gas and let out
Flow area.If it is oil layer pollution caused by the development processes such as well or oil recovery is being drilled, then oil gas current by pass should be dredged.
In order to increase oil gas drainage area, dredging oil gas current by pass increases the Liquid output of low yield liquid class low yield inefficient well,
Currently used means are the complete wells of acidification, pressure break and complex structural well (horizontal well, Multilateral Wells, extended reach well etc.), in recent years,
Radial direction well technology has also obtained a degree of application.Also there is apparent lack in some aspects in the existing advantage of these technologies
Point, for example, Acidizing Technology treatment radius is small, fracturing technique crack is uncontrollable, and complex structural well technology is drilled well complexity, when operation
Between it is long, the radial direction well technical operation time is long, needs high-tension apparatus etc..
Summary of the invention
The utility model is to solve technical problem present in well-known technique and provide a kind of non-sand control open hole well injection
Self-advancing type multiple-limb slim hole completion tool, the tool with the large and small borehole depth for the treatment of radius, simply may be used by controllable, construction operation
By etc. multiple advantages.
The utility model is adopted the technical scheme that solve technical problem present in well-known technique: a kind of non-sand control
Open hole well injection self-advancing type multiple-limb slim hole completion tool, including the injection pipe nipple that the tail pipe lower end with casing is connect,
The inside of the injection pipe nipple is equipped with the more branch's tubule lines being evenly distributed, and the import setting of branch's tubule line is covering
In the tail pipe of pipe, across the side wall for spraying pipe nipple, branch's tubule line passes through pipeline for the outlet of branch's tubule line
Seal nipple is connect with the side wall of the injection pipe nipple, is connected with self-advancing type nozzle in the outlet of branch's tubule line；?
The side wall of the injection pipe nipple is equipped with the check valve be inwardly connected.
The lower part of the injection pipe nipple is arranged in the check valve.
The top of the injection pipe nipple is arranged in the pipeline seal nipple.
The utility model has the advantages and positive effects of: by using more branch's tubule lines, using it is multiple from into
Formula nozzle is implemented broken rock and is crept into automatically, and the sprayable multiple branch's slim-holes of drilling of one-stop operation can effectively increase oil well output,
And the depth of branch's slim-hole can be controlled by the result of rock core test early period, can effectively wear out contaminated zone, dredging oil
Circulation road, compared with the conventional stimulation work such as acidification, pressure break, the controllable, construction operation with the large and small borehole depth for the treatment of radius
The multiple advantages such as simple and reliable.The utility model can be applicable in non-sand control oil field completion work, compared with current similar product, tool
Have that structure is simple, the reliable feature of performance safety.

Specific embodiment
For the invention, features and effects that can further appreciate that the utility model, the following examples are hereby given, and cooperates
Detailed description are as follows for attached drawing:
Please refer to FIG. 1 to FIG. 3, a kind of non-sand control open hole well injection self-advancing type multiple-limb slim hole completion tool, including
The injection pipe nipple 3 connecting with 3 lower end of tail pipe of casing is equipped with more points being evenly distributed in the inside of the injection pipe nipple 3
The import of branch tubule line 2, branch's tubule line 2 is arranged in the tail pipe 3 of casing, the outlet of branch's tubule line 2 across
The side wall of the injection pipe nipple 3, branch's tubule line 2 are connected by the side wall of pipeline seal nipple 4 and the injection pipe nipple 3
It connects, is connected with self-advancing type nozzle 5 in the outlet of branch's tubule line 2, positive spray-hole 5- is equipped on self-advancing type nozzle 5
2 and reverse propulsion hole 5-1 is equipped with the check valve 6 be inwardly connected on the side wall of the injection pipe nipple 3.
In the present embodiment, the lower part of the injection pipe nipple 3 is arranged in the check valve 6.The pipeline seal nipple 4 is set
