摘　　要：为解决稠油区块的增注及解堵问题,提高开发效果,针对河南南阳油田古城南三块注水开发区块进行了酸化技术及酸液体系与地层配伍性研究,建立了一套有针对性的酸化增注工艺技术.In order to overcome the problems of injection and plug removal in the heavy oil block to increase the development efficiency, and according to the state of the development by the water injection in the Gucheng South three block oil field of Henan Nanyang, the aciding technolgy, acid liquid system and its compatibility with the formation have been studied. On the basis of this study, a set of acidizing technology corresponding to the block has been established.
