摘　　要：正电胶/聚合醇/纳米乳液钻井液用于易发生垮塌油气藏勘探开发,有较好的防垮塌效果。根据胜利油田临南洼陷街斜2块的地质特点,优选了适合该区块防垮塌的钻井液配方,在街207井应用获得了成功。Application of positive colloid ＆polymeric alcohol ＆nano-emulsion drilling fluid in oil reservoir which is easily to collapse is a new technology. In the light of that borehole has collapsed severely in South Low-lying Street Xie-2 Block when drilling, drilling fluid system appropriate to the block has been optimized. Positive colloid, polymeric alcohol and polymer are used to control formation slurry production. Double-protection nano-emulsion is used to strengthen the anti-slumping property of drilling fluid. All above has achieved success in Jie207 well.
