摘　　要：The reservoir of block Du 66 in Shuguang Oilfield is unevenly developed, and development contradictions continue to appear. The contradiction in the middle and late development is more obvious. In order to make its development effect more effective, the experiment of air injection assisted steam huff and puff oil production technology was carried out in Du 66 oilfield, and good results were obtained. In order to solve the problem of uneven suction (steam) between oil layers, through the self-designed layer selection air injection gas pipe column, the suction volume of each oil layer meets the design requirements, so that the oil reservoir can be effectively produced vertically, so as to obtain good economic benefits, which is conducive to the popularization and application of this technology.
