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。本文论述的研究和实验方法可为陆相复式油气区多种储层类型的油层改造提供技术参考
In order to improve the success rate of acidizing and reforming oil formation and the daily output of single well crude oil, the paper developed two main oil-storage rocks, carbonate rock and clastic sandstone, by using the micro-lithology analysis technology of reservoir and chemical theory of oil field and drilling technology. Type of reservoir permeability formula, proposed an effective method to improve the permeability of the reservoir. Based on the acidizing formula developed by reservoir lithology and physical property development, different reservoir types in Puxi, Fanjia and Shenghai have been carried out on site and significant economic benefits have been achieved. The research and experimental methods discussed in this paper can provide technical reference for the reservoir reconstruction of various reservoir types in continental oil and gas fields
