摘　　要：鄂尔多斯盆地苏里格气田水平井钻遇“双石组”层反复划眼、阻卡、甚至卡钻,结合地质特点以及技术难点,摸索出一套与该区块水平井造斜段水平段相匹配的抑制性强的低固相聚磺钻井液体系及其工艺技术,能满足优质快速低成本钻井需求。When drilling horizontal wells in Sulige gas field,Ordos Basin,the"Shuangshi formation"layer is repeatedly reamed,stuck,or even stuck.Combined with geological characteristics and technical difficulties,a set of low solid phase polysulfonated drilling fluid system and its technology with strong inhibition matching with the horizontal section of the deflecting section of horizontal wells in this block are explored,which can meet the needs of high-quality,fast and low-cost drilling.

关 键 词：造斜段阻卡 强抑制 强封堵防塌 润滑防卡
