Steel wire rope for deep sea oil field lifting and production method thereof

Abstract

The invention provides a steel wire rope for deep sea oil field lifting. The steel wire rope comprises a center rope strand, an outer layer strand and a plastic-coated layer surrounding the outer layer strand, the steel wire rope takes the center rope strand as the center, the outer layer strand is wrapped and twisted on the periphery of the center rope strand, a first filling layer is mounted between the center strand and the outer layer strand, the center rope strand is provided with a center strand and an outer rope strand, the center strand is located on the center of the center rope strand, the outer rope strand is wrapped and twisted on the periphery of the center rope strand, the outer rope strand is mounted in a hexagon manner, the outer layer strand is provided with a first outerlayer strand and a second outer layer strand which are mounted in a spaced manner, the first outer layer strand and the second outer layer strand are twisted in parallel, and the steel wire rope has the good wear resistance and corrosion resistance, is suitable for the seabed low-temperature work, and has the good high and low temperature resistance property and transverse pressuring resisting capacity.

Description

technical field [0001] The invention relates to the technical field of steel wire ropes, in particular to a steel wire rope for hoisting in deep sea oil fields and a production method thereof. Background technique [0002] Steel wire rope is composed of steel wire, rope core and lubricating grease. It is firstly twisted into strands by multi-layer steel wires, and then centered on the rope core, it is a spiral steel bundle twisted together by a certain number of strands; the steel wire rope has high strength, light weight, It is not easy to break the whole root suddenly, and the work is reliable. [0003] Seabed oil is one of the mineral resources buried in sedimentary rocks and bedrocks below the bottom of the ocean. The exploitation of seabed oil (including natural gas) began in the early 20th century, but only a small number of seabed oil fields were discovered for a long period of time. It was not until the late 1960s that the exploration and exploitation of offshore oi...

Problems solved by technology

However, due to the harsh environment in which the steel wire rope is used for lifting, the anti-corrosion and anti-rust grease applied to the surface of the steel wire rope is easy to dry and age, and the steel wire rope is corroded, which shortens the service life of the steel wire rope; Some steel wire ropes have poor lateral pressure bearing capacity in the deep sea. The steel wire rope is subjected to lateral pressure, which often deforms the steel wire rope and seriously affects the service life of the steel wire rope. In addition, the temperature in the deep sea is low. Working under the condition, the steel wire rope is easy to break when it is used, and the service time of the steel wire rope is shortened
