基于轨迹控制的煤矿井下复合定向钻进工艺
Composite Directional Drilling Technology for Underground Coal Mine Based on Trajectory Control
摘要
Abstract
In order to solve low efficiency and poor ability problems of the continuous sliding directional drilling technology used in underground coal mine,the composite directional drilling technology is presented.Then,the meaning of composite directional drilling technology is clarified and its technical characteristics are analyzed from trajectory control.The technical characteristics of composite directional drilling technology are summarized through typical examples:strong ability and high efficiency.The application effect includes that the maximum depth of borehole in the seam reaches 1 881 m,the maximum depth of borehole in the roof strata reaches 1 026 m,the maximum depth of dealing with stuck accident reaches 1 188 m,the average mechanical drilling efficiency is increased by more than 20％,the comprehensive drilling efficiency is improved by more than 40％.The composite directional drilling technology revolutionizes the trajectory control mode and promotes the construction capability of deep borehole,ultra-deep borehole and largediameter directional borehole in the roof strata of underground coal mine.关键词
