摘　　要：本文通过辽河油区转驱最早的曙１－７－５块５ａ多的开发实践，对块状边底水油藏蒸汽驱阶段的动态规律进行了初步探讨，提出蒸汽驱开发的生产特征和变化规律，以及压力和温度的变化特征，并提出了测算蒸汽驱油藏原油采收率的注采特征曲线法和水驱特征曲线法，同时提出了确定蒸汽驱油藏最大油汽比和最佳注汽速度的统计方法。这些方法和动态变化规律，对今后我国稠油的大规模开采具有重要的指导和借鉴意义。This paper presents some preliminary research results on the performance of a reservoir with edge and hot tom water drive during steam flooding period, based on more than 5 years experience of Block Shu 1-7-5,Liaohe oilfield, which is the earliest block of steam injection in Liaohe region. This paper gives the characteristics and regulatities of production under steam flooding, and presents two methods-injection and production characteristic curve and water drive characteristic curve for the estimation of oil recovery by steam flooding. At the same time, the paper introduces a statistical method for determining the maximum GOR and optimum steam injection rate. These methods presented above will be of interest for guiding large scale steam injection in the future.
