对提高川东石炭系深井钻井速度的探讨

HOW TO IMPROVE THE DRILLING SPEED IN EAST SICIIUAN CARBONIFEROUS FOR DEEP DRILLING

随着川东地区钻探工作的不断深,钻井地质情况越来越复杂;钻井深度越来越深入;钻井难度越来越大;严重地制约了川东石炭系深井的钻井速度。通过分析影响川东钻井速度的主要因素,提出了提高川东石炭系深井钻井速度的主要技术途径及主攻方向。

As the depth of exploration increases, the geologic conditions become more complex; drilling depth become greater and drilling become more difficult. All these problems greatly influence the drilling speed in Carboniferous deep drilling of East Siehuan. By analying the main factors that affect the drilling speed,the new technical approaches are provided.
