Abstract
A set of large diameter wire-line coring tool is developed to solve the difficulties in large diameter deep hole and soft formation drilling.The paper introduces its structure characteristics, technical parameters, technical innovation and the application effects.The application effects show that this drilling tool has the advantages of rational structure, reliable mechanism action and high coring rate and can meet the coring requirements in deep hole and soft formation.关键词
