Abstract

The invention discloses a quick cable connector capture short segment which is characterized by comprising an upper connector, a return spring, a divided cone block and a lower connector, wherein the lower end of the upper connector is provided with the return spring; the upper end of the lower connector is provided with the divided cone block; the lower end of the upper connector is connected with a thread on the upper end of the lower connector; and the return spring compresses the divided cone block. The quick cable connector capture short segment has a novel structure, can be used under high-temperature and high-pressure conditions, is safe and reliable; can realize the transmission of pull pressure and torque as well as current and electric signals under normal circumstances, can capture (clamp) a quick cable connector when the quick cable connector falls off or is broken so that a cable below the quick cable connector is prevented from falling to the bottom of a well through a test pipe column and thus causing complicated accidents.

Description

technical field [0001] The invention relates to the field of petroleum engineering, in particular to a fast cable joint catching puppet connected to a test pipe string. Background technique [0002] During well logging operations, if the cable quick connector falls off or breaks, the cable quick connector and the following cables fall into the test string, causing complex accidents. [0003] The existing cable quick connector catcher is a simple "C" type side opening disc. The defect of the cable quick connector catcher with this structure is that it is easy to slip off and the installation is complicated. Contents of the invention [0004] In view of the above problems, the object of the present invention is to provide a cable quick connector catching sub that can prevent the cable below the cable quick connector from falling off to the bottom of the well. [0005] In order to achieve the above purpose, a quick cable joint catching nipple according to the present inventi...
