摘要
江西省有许多水工建筑物的持力层为白垩系和第三系软岩.为保证软岩的钻探质量,提高软岩钻探效率,介绍了第三系泥质粉砂岩软质岩层的钻进参数选择和钻探工艺.
The supporting course of a lot of hydraulic engineering works in Jiangxi province is the soft rock of Cretaceous system and Tertiary system. The drilling parameter selection and technology improvement of the soft rock of argillaceous sihstone of Tertiary system were introduced in order to insure the drilling quality and improving the drilling efficiency of soft rock.
