摘要
白 5 6井完钻井深 4 6 5 0m ,是白庙区块第一口超过 4 5 0 0m的深井。上部地层 (330 0m以上 )采用聚合物正电胶钻井液体系 ,中深井地层 (330 0～ 4 4 98m)采用聚磺钾盐钻井液体系 ,下部地层小井眼采用聚磺正电胶钻井液体系。现场使用表明 ,聚合物正电胶钻井液具有独特的流变性、抑制性和较强的防塌能力 ,聚磺钾盐钻井液具有防塌性能好 ,抗高温能力强 ,聚磺正电胶钻井液具有低粘高切特性 ,降低井眼环空压力损耗 ,满足了白 5 6井各井段钻井施工要求。
Well Bai-56 is the first deep well over 4500m in Baimiao tract.Its well depth is 4650m.During drilling the well Bai-5,ploymer MMH drilling fluid system is used in the upper section (over 3300m),polymer-sulfonated-potassium drilling fluid system is used in middle deep section(3300～4498m),and polymer-sulfonated MMH drilling fluid system is used in the slim hole of lower section.The application of these drilling fluid proves that 3 kinds of drilling fluid systems can meet the requirement of drilling operation in well Bai-56.
