Stainless steel closed double-steel-wire armored logging cable

The utility model relates to a stainless steel enclosed double-steel-wire armored logging cable, which comprises a cable core, the outer layer of the cable core is a fluoroplastic insulating layer, and a polypropylene inner layer sheath is coated outside the fluoroplastic insulating layer; a stainless steel sealing sleeve is coated outside the polypropylene inner layer sheath; a polypropylene outer sheath is coated outside the stainless steel sealing sleeve; an inner steel wire armor layer is arranged outside the polypropylene outer sheath, and an outer steel wire armor layer is arranged outside the inner steel wire armor layer. The cable adopts a one-core structure, a one-core tinned copper conductor is electrified, and a steel wire of an outer steel wire armor layer serves as a loop to be grounded; the cable with the structure can bear a certain tension load to hoist an instrument to be constructed in an oil well, a gas well and other environments requiring under-pressure operation;by adopting the stainless
