摘要
濮城油田区域构造位于东濮凹陷中央隆起带北部,包括濮城主体、濮卫次洼、户部寨三个含油气构造,是一个油藏埋藏深、孔隙度小、渗透率低、非均质严重的断块油(气)藏。普通常规酸化效果较差,高效返排缓速酸化可有效提高酸化效果,改善地层流体的渗流能力。
Pucheng oil field is located in the north of Dongpu depression,which includes some reservoirs buried deeply. Some of them are low permeability and low porosity and severe heterogeneity. The result of normal acidizing is not ideal, and the deep acidizing with inhibitory acid of high effective removal can be adapted for increasing the porosity and permeability.
