Description

Technical Field

[0001] The invention relates to the technical field of oil drilling logging, and is a network slot for laying cables of an oil comprehensive logging instrument and a network slot laying method. Background Art

[0002] Cable transmission is a common way to transmit signals collected by integrated logging instruments. According to the requirements of the "Technical Specifications for On-site Installation of Integrated Logging Instruments", the integrated logging instrument should be placed in a safe position 30 to 35 meters away from the wellhead. The cables, signal lines and sample gas pipelines between the instrument room and the drilling rig vibrating screen must be installed at high altitude, and the height of the cable pole should not be less than 3 meters. In order to ensure the stability of the cable installation, the logging site has used 5mm diameter steel wire ropes as load-bearing ropes for many years. All signal cables and sample gas pipelines are tied to the load-bearing steel wire ropes with a tying spacing of 0.5 to 1m. There are more than 10 integrated logging instrument signal cables, power supply cables and gas sample pipelines, weighing dozens to hundreds of kilograms. Special lifting equipment is required to lift the cables to a height of 3 meters and fix them at both ends to make them as horizontal as possible. The cable installation operation is not easy.

[0003] The main disadvantages of the traditional cable-hanging method currently used in the installation of comprehensive logging instruments are: the cables need to be bundled and fixed to the wire rope, and the installation and removal are time-consuming and laborious. Usually, a 30-35m logging cable needs to be tied with a bundle of straps or strapping ropes in more than 50 places, which is very troublesome; the overall weight of the cable and the wire rope is large after being bundled together, and 3-4 people are required to lift and use lifting equipment together to lift the entire bundle of cables and fix them in the air; multiple cables are bundled together, and the heat dissipation effect of the cables is poor, which is easy to cause signal interference and affect the stability of the signal; the maintenance is difficult, and when any one of the cables fails, the bundled cables must be loosened from the air as a whole, and then the strapping tape is loosened to find the problematic cable. After the maintenance, it needs to be re-bundled and then re-lifted and fixed on the cable pole; the bundled cables look messy and unsightly; the strapping rope or strapping tape cannot be reused after use, resulting in a waste of resources; there is a lack of obvious safety signs, the safety reminder effect is poor, and there is a risk of the cable being hung up by the crane construction. Summary of the invention

[0004] The present invention provides a cable installation net trough for petroleum comprehensive logging instrument and a net trough installation method, which overcomes the shortcomings of the above-mentioned prior art and can effectively solve the problems of time-consuming and labor-intensive disassembly and assembly, poor cable heat dissipation effect and poor aesthetics of the conventional cable installation of the existing comprehensive logging instrument.
