Abstract

The invention provides a photoelectric separation connection device, comprising: a plurality of joint assemblies, each joint assembly has a photoelectric separation part and a plurality of adapters, the adapters are fixedly arranged, and the photoelectric separation part separates the cable and the optical fiber of the photoelectric composite cable , the separated cables and optical fibers are connected with the adapter; the connection assembly, each joint assembly is connected through the connection assembly, and together with the connection assembly forms a sealed cavity, the adapters of different joint assemblies pass through the sealed cavity The connection lines are connected in one-to-one correspondence. The invention solves the problem of poor sealing of the photoelectric separation connection device in the prior art.

Description

technical field [0001] The invention relates to the technical field of petroleum well logging, in particular to a photoelectric separation and connection device. Background technique [0002] At present, fiber optic micro-seismic detectors and fiber-optic micro-seismic monitoring technologies have been widely used abroad, not only for guiding the fracturing process in many places, but also for real-time geophysical monitoring and well completion processes. During the use of the above-mentioned instruments, it is often necessary to connect and seal the cables and optical fibers in the photoelectric composite cable with the cables and optical fibers in the downhole photoelectric collection nipple respectively, but there is no corresponding device in the prior art, and With the traditional connecting device, the sealing of the connection is poor, and the oil and gas in the well will affect the monitoring data obtained by the optical fiber and cable, resulting in the problem of ...
