摘要
塔里木油田天然气随2000年10月牙哈23凝析气田投产之后,到目前为止,先后投产了克拉2气田、桑吉气田、英买力气田群,其中克拉2气田、迪那凝析气田均属异常超高压气藏,原始压力系数超过2.0MPa/100m。部份井在完井放喷过程中出现了套压异常升高的现象,少数井出现了技术套压、表层套压异常情况,引起了中国石油高层高度关注,及时提出了评估及治理相关要求。已与哈里伯顿公司合作对克拉2气田的16口井从方案设计、钻井、完井、工具准备、完井工艺、生产历史、生产管理等进行了深入分析,进行了风险评估,并制定了应急预案,目前已投产井生产正常。
The Kela 2 gas field and Dina condensate field of Tarim Oilfield belong to surpressure gas reservoirs,their virgin pressure coefficient is over 2.0MPa/100m.Some wells appear casing pressure uprising during completion and blow off,few wells appear abnormal intermed casing pressure and surface casing pressure.According to these problems,some processing schemes were put forward,and the conceptual design,drilling technology,completion technology,producing history and production management were analyzed in detail.Meanwhile,the drilling risk assessment was carried out and the emergency project was established.Now,these wells have produced normally.
