复合钻井技术在塔木察格易斜区块应用效果

摘要

对塔木察格区块地质结构进行了调研分析.明确易斜地层为大漠拐河组合南屯组.运用有限元法对底部钻具组合进行了屈曲分析和优化.实践表明在易斜地层实施复合钻井技术,防斜、打快的效果明显.%Investigation analysis on geological structure of Tamuchage oil field is made, clear the highly deviated formation.Damoguaihe group and Nantun group and carried buckling analysis and optimization on the bottom hole assembly based on finite element method.Practice shows that the effect of rapid inclining prevention drilling obviously by applying combined drilling technology in highly deviated formation.
