Problems solved by technology

When the umbilical-cable integrated coiled tubing is connected to each other using the existing connector 4, the existing connector 4 can only complete the interconnection of the coiled tubing body 1 (see the attached figure 2 ); the outer cable 3 needs to peel off the protective layer 2 and then connect the cable 3 directly; in this way, the connecting part between the cables 3 will be directly exposed to the outside, and there is a problem of corrosion or even breakage caused by lack of protection

Abstract

The invention relates to a umbilical cable integrated continuous tubing connector assembly, which belongs to the technical field of downhole tools and equipment. The umbilical cable integrated coiled tubing connector assembly includes wellhead connectors, pipe-to-pipe connectors and bottomhole connectors; the wellhead connectors include tee sleeves, connecting flanges, terminal blocks and valve covers; tee sleeves The lower end port of the barrel is provided with a connecting flange; the side port of the tee sleeve is press-fitted with an intermediate piece through the valve cover; the valve cover is fixedly connected with the tee sleeve through locking bolts; the intermediate piece and the valve cover Terminals are installed between them. The umbilical-cable integrated coiled tubing connector assembly has a compact structure and an ingenious design; when used, it can not only meet the connection requirements of the coiled tubing body of the umbilical-cable integrated coiled tubing, but also can connect cables conveniently, and can better control the joints of cables. The protection is carried out, thereby solving the problem that the cable junction is easy to break when the umbilical integrated coiled tubing is connected with the existing connector.

Description

Technical field [0001] The present invention relates to a unitary continuous tube umbilical connector assembly technical field belongs to the downhole tools and equipment. Background technique [0002] In the field of oil exploration and production, due to the continuous tube has a job with undervoltage balance, high operating speed efficiency, low formation damage, and low cost advantages and enormous practical value, is widely used in oil drilling projects. In the course of a continuous tube is required between the tube and the tube a continuous tube connector connected to each other; downhole required interconnection between the connector and the coiled tubing downhole electric submersible pump and other equipment; continuous tubular upper end of the wellhead Christmas tree required between the wellhead connector are interconnected. These three connectors known as "umbilical continuous integral pipe connector assembly." Conventional connectors are able to meet the needs of the...
