Control cable for oil and gas downhole instrument and manufacturing method thereof

The invention discloses a control cable for an oil and gas downhole instrument and a manufacturing method thereof, belonging to the technical field of cables. The control cable comprises a steel wirerope, three cable cores, a silica gel layer, a fiber cloth layer, a rubber inner liner layer, an armor layer and an outer protective layer, wherein the steel wire rope and the three cable cores are mutually twisted together to form a composite cable core, the silica gel layer coats the outer sides of the three cable cores, the fiber cloth layer coats the outer side of the silica gel layer, the rubber inner liner layer coats the outer side of the armor layer, and the outer protective layer coats the outer side of the armor layer. The control cable for the oil and gas downhole instrument and themanufacturing method thereof can effectively enhance the wear resistance, corrosion resistance, tensile resistance and magnetic field resistance of the cable, can prolong the service life of the cable, can ensure the use safe
