深部调驱技术在歧五断块的应用

Application of Deep Profile Correction Technology in Qi- wu Fault Block

针对大港王徐庆油田歧五断块水驱效果变差,油井含水上升,递减加快的问题,开展了精细油藏描述研究和井间化学示踪剂监测工作,在搞清剩余油分布和水道变化情况的前提下,制定并实施了大剂量深部调驱方案,在4口注水井实施了6井次深部调驱,平均单井次注入调驱剂量3 954m^3,对应8口油井先后见效,累计增油6 900t,应用效果良好。

In viewing of the deteriorating waterflooding effects, escalating water cut and accelerating production decline in Qiwu fault block in Xuzhuang oilfield, fine reservoir description and inter - well chemical tracer monitoring are performed. Based on deep understanding of remaining oil distribution and water channel changes, a massive deep profile correction plan is drawn up and implemented. Six deep profile operations are carried out in 4 water injection wells and the average amount profile correction agents used in single operation is 3,945m3. Eight corresponding wells respond successively leading to a cumulative incremental oil production of 6,900 tons.
