摘要
为了提高酸化改造油层的成功率和单井原油日产量 ,运用储层微观岩石学分析技术和油田化学、钻采工艺学原理 ,研制了提高碳酸盐岩和碎屑砂岩两种主要储油岩石类型油层渗透率的酸配方 ,提出了有效提高油层渗透性的实验方法。根据储层岩性、物性发育特点研制的酸化配方 ,对桩西、樊家和胜海地区的不同油藏类型进行了现场实施 ,取得了明显经济效益。
An acidizing fluid for improving reservior permeability was developed by application of reservior lithology, oil field chemistry and drilling technology,which greatly increased success of reservior modification and daily product of single well.It showed that the fluid have successfully been applied to different reserviors in Zhuangxi,Fanjia,Shenghai areas and gained big benefit.There is a bright prospeet for application of acidizing fluid to various reserviors of non marine complex oil province.
