Abstract: Aimed at the demand of drilling rigs for reduction of weight, ultra-high strength steel wire rope meets the need for rig rope used for ZJ90 and ZJ80. Compacted wire rope of EEIP grade, with new performance, is developed on the basis of the research on structure and functions of wire rope. As compared to ordinary drilling steel wire rope, this product is improved by more than 12 percent for its tested breaking force and 70 percent for its anti-fatigue function while its wear resistance is doubled. The steel wire rope is reduced in diameter but reaches the requirements of drilling rig. This is a major technological upgrading of drilling steel wire rope, laying a solid technical foundation for reduction of rig weight in China.
