摘要
通过对原双筒单动取心工具的技术革新,重新设计水眼,改造岩心爪,配合相应的钻井液和钻井参数选择措施,第四系取心获得成功。
By way of redesigning the water hole, reforming core gripper and with selecting corresponding drilling liquid and parameters, the original single-slide dual-barrel coring tools are enabled to suit the coring operation in Quatanary sediments and its core recovery is obviously enhanced.
