摘要
酸化是油井常用解堵引效措施,但是由于油田区块地质特征不同,油井酸化后的反应也不尽相同。本文主要根据王场油田西区王广区块低渗透油藏油井在油层堵塞后运用酸化解堵引效案例进行分析及总结规律,以保证油井酸化有效率。
Acidification is a common plugging removal and induction measure in oil wells,but because of the different geological characteristics of oilfield blocks,the reactions of oil wells after acidification are also different.In this paper,according to the case of acidizing plugging removal in low permeability reservoirs in Wangguang block of Wangchang oilfield,the author analyzed and summarized the law to ensure the acidizing efficiency of oil wells.
