摘要
洪斜 56井是洪浩尔舒特凹陷东次洼海流特构造洪 4 6南断块上的一口预探井 ,常规试油低产。针对该井储层泥质含量高、水敏性强、井筒周围已造成污染等情况 ,优选出压裂施工方案 ,即在压裂施工过程中 ,采用了复合防膨技术 ,及大砂量、高砂比等多项试油新工艺。压裂后 ,获日产原油 19.94m3,超过了压裂前的预测产量 。
The slant Hong 56 well is a wildcat well on Hong 46 south fault block of east Ciwa ocean current structure in Hong Hao′er Shute sag.Its conventional oil production rate is low productivity.Since the reservoir is high shale content,water sensitivity and wellbore damaged,the constructional optimizing fracturing project are performed.During the fracturing project,some new technologies,such as compound anti expansion technology,massive sand,high sand ratio technology etc.are used.After fracturing,the oil production rate is raised to 19.94 m 3/d,which is more higher than that before fracturing.It is favorable to social and economic benefit.
