摘　　要：Qi 40 block has entered the late stage of steam drive development with large production decline. Since 2012, Qi 40 steam drive has entered the stage of production decline, with an annual decline of 6.6%, and the oil steam ratio of some well groups is lower than 0.1, increasing the cost of heavy oil thermal recovery. The measures of cost optimization, variable dryness steam drive, parameter optimization and intermittent steam drive have been taken to comprehensively improve the oil well production and improve the later development effect and economic benefit of steam drive.
