摘　　要：随着吞吐采出程度的加深，河南稠油油田油层压力下降较快，老井产量星下降趋势，吞吐效果和经济效益逐渐变差。为进一步提高油藏采收率，提高老油田的开发效果，在井楼油田楼资27井区进行了过热蒸汽驱现场试验，开展了楼资27井区汽驱注采工艺配套适应性评价，为河南油田下一步蒸汽驱现场试验提供技术参考。With the increase of oil recovery percent of steam soaking,pressure in heavy oil reservoirs of Henan Oilfield decreased rapidly and production rate in old wells also decreased,therefore steam soaking effect and economic benefit became poor.To further enhance oil recovery ratio and improve the production effect of old oilfields,field test of overheat steam drive is carried out in Block Louzi 27,and the adaptability evaluation is conducted on the matching techniques,and good result is obtained.It provides a technical reference for next field test of steam drive.
