摘　　要：介绍了近期在配制完井液时使用的两项新技术:对钻井液完井液滤饼进行溶蚀实验研究,清除内外滤饼技术研究;国外工作者在研究中得到的一些结论以及酶处理的完井液。同时介绍了两种新评价程序:地层损害评价实验程序(使用动滤失仪CDFC);预制筛网损坏评价程序(使用预制筛网堵塞实验仪器MCDFC)。This paper presents two new technologies for preparing drill-in fluid, i. e. , filter cake dissolving study and removal of inside and outside filter cake technology. Some study achievements in this field is reviewed, and the enzyme treated completion fluid is described. Two new programs for formation damage evaluation are also described. These studies and technologies are beneficial for the removal of formation damage, especially in horizontal well.
