To improve the development efficiency of low permeable reservoir, an experimental study on plug removal of combining physical and chemical methods has been conducted on the basis of extracting advantages of similar technology in the country. In the light of geologic features of A-nan oilfield, the major factors that cause reservoir pollution and plug have been analyzed. The plug removal principles of rotary fluidics, chemical agents and the combination of the two have been discussed. In addition, the performance of HB compound plug removal agent, the technology and effectiveness of application in the oilfield have also been discussed.
