摘要
根据准噶尔中部1区块三工河组储层特点,在充分考虑油藏孔喉非均质性的情况下,利用广谱屏蔽暂堵技术进行架桥粒子和填充粒子设计,通过室内实验,进行钻井完井液配方的优选。该技术在准噶尔中部1区块使用后效果明显,渗透恢复率达到95%以上,试验井表皮系数均为负值。
The frame grains and filling grains were designed by using temporary shield blocking techniques, taking account of heterogeneous apertures and following the reservoir features of Sangong Structure in 1^(st) district of Sungar. The drilling fluid formula was optimized after indoor test. The techniques gained very good application results in 1^(st) district of center Sungar. The permeation recovery rate reached over 95%. The surface ratio of test well all were negative.
