摘要
碳酸盐岩水平井以常规笼统改造方式为主,酸压裂缝对储层的沟通程度有限。水平井段长,滤失量极大,酸岩反应速度快,酸液损耗严重。因此,需要开展水平井分段酸化压裂工艺技术研究,从分段改造工具的研制入手,形成深层碳酸盐岩水平井分段酸压工艺技术系列。
Horizontal wells in carbonate rock are mainly reformed by general methods,and the communication degree between acid fracturing and reservoir is limited. The horizontal well section is long,the filtration quantity is huge,the acid rock reaction speed is fast,and the acid liquid loss is serious. Therefore,it is necessary to carry out the technology research of horizontal well sectional acidizing fracturing,starting with the development of sectional reconstruction tools,forming a series of deep carbonate horizontal well sectional acidizing fracturing technology.
