Downhole switch sliding sleeve installation machine and installation operation process

Abstract

The invention relates to a downhole switch sliding sleeve installation machine and an installation operation process. The machine comprises a conveying frame, two conveying frame units, an assembly detection unit, a driving air cylinder, and a synchronous plate, wherein the two conveying frame units are installed on the middle part of the conveying frame, the assembly detection unit is installed at the left end of the conveying frame, the driving air cylinder is installed at the right end of the conveying frame, and the synchronous plate is installed at a protruding end of the driving air cylinder. The downhole switch sliding sleeve installation machine and the installation operation process can solve the problems that because an inner drum is tightly sleeved with an outer drum, in the process of manual sleeving operation, the sleeving operation can only be successfully completed after repeated sleeving; that if the drums are forcibly sleeved with each other, slight bending of the drumbodies may be caused, so the degree of smooth sliding between the inner drum and the outer drum is lowered and a defective product is thereby made; and that because no specific equipment is applied to the detection of the degree of smoothness, a defect cannot be timely discovered and disposed.

Description

technical field [0001] The invention relates to the field of downhole installation technology, in particular to an downhole switch sliding sleeve installation machine and an installation construction process. Background technique [0002] In the cementing process, the switch sliding sleeve is directly connected with the casing through the casing buckle and arranged in each production layer. In the later stage, the sliding sleeve is opened by the switch tool for fracturing and stimulation operations, or the sliding sleeve is closed for selective mining, or for sealing and water blocking operations on some layers. It is a commonly used tool in the downhole. , it is necessary to manually set the inner cylinder and outer cylinder of the switch sliding sleeve, and some problems are often encountered during the sleeve: [0003] Since the inner and outer cylinders are tightly fitted, it may be necessary to repeatedly set the sleeves manually to successfully set them up. When the t...

AI Technical Summary

Problems solved by technology

[0003] Since the inner and outer cylinders are tightly fitted, it may be necessary to repeatedly set the sleeves manually to successfully set them up. When the two are forcibly set, the cylinder body may be slightly bent, thereby reducing the inner and outer cylinders. The smoothness of the sliding between them has become a defective product, and there is no special equipment for the detection of the smoothness, resulting in failure to detect and deal with it in time
