摘　　要：酸化解堵工艺在油田的应用已经比较普遍,而且各大油田根据地层实际情况对酸液体系进行了优化和改进。主要从酸化原理、体系分类及体系应用三个方面介绍该工艺技术在低渗透碳酸盐岩油藏和低渗透砂岩油藏的应用。实际应用表明:酸化解堵技术能够有效解除近井地带的堵塞,改善和恢复地层的渗透率。The acidizing plugging removal technology has been widely used in oilfields,and the acid system has been optimized and improved according to the actual situation of the formation in major oilfields.This paper will introduce the application of this technology in low permeability Carbonate rock oil reservoirs and low permeability sandstone reservoirs from three aspects of acidizing principle,system classification and system application.
