针对气体钻井过程中地层出水、扭矩、摩阻过大或起下钻困难、影响钻井安全等复杂情况的发生而不得不转换成常规钻井液钻井的问题,通过对气液转换过程中工作液对井壁稳定的影响机理分析,由此而提出气液转换对钻井液性能要求,提出进行钻井液转换时可考虑先采用较低密度的钻井液,待钻井液在井壁形成滤饼后再提高钻井液密度平衡地层流体,所选用的水基钻井液可以考虑强抑制乳化防塌钻井液、非渗透钻井液、聚硅醇钻井液、设计者钻井液(designermud)、MEG钻井液和聚合物沥青钻井液。
补充资料:槽壁法施工
在松软地层中建造地下连续墙的施工方法。从地面上沿预定墙身位置,使用专用机具(抓斗或钻孔机等)分段挖槽,槽内用泥浆护壁,借泥浆循环或机械方法出土。挖成6~8米一段深槽后,放入钢筋笼和接头模型,并在泥浆内应用导管浇灌混凝土。如此逐段进行挖槽筑壁便建成连续的钢筋混凝土墙,称为“地下连续墙”。常用于建造地下建筑工程的基坑挡土墙、工程结构的边墙和水利工程的大坝防渗墙等。
