A downhole switch sliding sleeve installation machine and installation construction technology

Abstract

The invention relates to a downhole switch sliding sleeve installation machine and its installation and construction process, comprising a conveying frame, two conveying frame units, an assembly detection unit, a driving cylinder and a synchronous plate, and two conveying frame units are installed in the middle of the conveying frame , The assembly detection unit is installed on the left end of the conveying frame, the driving cylinder is installed on the right end of the conveying frame, and the synchronous plate is installed on the ejection end of the driving cylinder. The present invention can solve the problem that due to the tight sleeve between the inner and outer cylinders, repeated sleeves may be required to successfully sleeve during manual sleeves. When the two are forcibly sleeved, the cylinder may be slightly bent, thereby reducing the The smoothness of the sliding between the inner and outer cylinders has become a defective product, and there is no special equipment to detect the smoothness, resulting in failure to detect and deal with problems in time.

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...

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
