在注水开发过程中，悬浮物微粒、原油及其它有机难容污染物逐渐堵塞孔隙，导致近井地带渗透率降低。为减少外来液侵袭造成近井地带冷伤害，近井地带清堵是现有绝大多数油、水井措施工艺的主要手段。根据沈阳采油厂原油物性及二氧化碳“超临界液体”特性研究出一套复合酸解堵技术。

In the process of water-injection development, suspended substance particles, crude oil and other organic unsolvable pollutants gradually block the space and thus result in the decrease of permeability near wellbore zone. In order to reduce the cold harm near wellbore zone caused by the attack of outside fluid, plug removing near wellbore zone is the main means of most oil and water well technologies. According to the property of crude oil and the "supercritical" characteristics of carbon dioxide in Shenyang Oil Production Plant, a set of combined acidity plug removing technology is developed.
