Carbon fiber optic load-bearing detection cable for oil and gas exploration robot

Abstract

The invention discloses a carbon fiber optical fiber load-bearing detection cable for an oil and gas exploration robot, comprising a stainless steel pipe and a bracket arranged in the stainless steelpipe, wherein a plurality of cavities are formed between the bracket and the stainless steel pipe, an optical fiber unit is arranged in the cavity, and a water blocking agent is filled in the cavity;A lay of aramid fiber, an inn layer of carbon fiber and an outer lay of carbon fiber are sequentially arranged outside that stainless steel pipe. The invention is provided with two layers of carbon fiber, there is no need to add a layer of armor to the outer layer, The invention replaces the traditional double-layer stainless steel armor layer, greatly reduces the weight of the whole cable, and greatly improves the load-bearing performance of the cable. The aramid fiber layer and the carbon fiber layer are combined to make the cable high-temperature resistant, corrosion resistant, light weight, tear-resistant, strong load-bearing capacity, long service life, and ensure the high-quality and stable oil and gas exploration work.

Description

technical field [0001] The invention belongs to the technical field of detection cables, and in particular relates to a carbon fiber optical fiber load-bearing detection cable for an oil and gas exploration robot. Background technique [0002] In the exploration and logging operation of high temperature and high pressure oil and gas wells, the downhole logging instrument and the monitoring equipment on the ground are usually connected by detection cables. High temperature and high pressure oil and gas wells contain H 2 S and other corrosive gases, and the pressure is high, the cables that go deep into the well must have good corrosion resistance and compression resistance, and the detection cables must also bear the weight of the downhole equipment, and need to have excellent load-bearing capacity and tensile properties. Some detection cables use a metal armor layer, and a large amount of metal materials are used, which makes the weight of the cable itself heavy, and the cor...

[0002] In the exploration and logging operation of high temperature and high pressure oil and gas wells, the downhole logging instrument and the monitoring equipment on the ground are usually connected by detection cables. High temperature and high pressure oil and gas wells contain H 2 S and other corrosive gases, and the pressure is high, the cables that go deep into the well must have good corrosion resistance and compression resistance, and the detection cables must also bear the weight of the downhole equipment, and need to have excellent load-bearing capacity and tensile properties. Some detection cables use a metal armor layer. The amount of metal material used makes the weight of the cable itself heavy, and the corrosion resistance of the metal is not good enough, resulting in a short service life of the cable and affecting the signal transmission capability.
