摘　　要：丫角油田以短轴背斜层状油藏为主,其次为透镜状及断层遮挡油藏。油层单层厚度薄,渗透率低,含油饱和度偏低,为普通稠油,具有高比重、高粘度、高含硫的特点。在对丫角油田浅层稠油进行的热采试验中,所采用的热采工艺是成功的。针对丫角油田薄层稠油热采,应选择低含水油井并采用较大的注汽强度,才能保证热采效果。Yajiao Oilfield consists mostly of brachyanticline stratified reservoirs, accompanying with lentoid and fault screened reservoirs. Each single layer of the reservoirs is thin and has low permeability and oil saturation. It contains common heavy oil with the characteristics of high specific gravity, high viscosity and high sulfur. The thermal recovery technology adopted in the experiment on thermal recovery of shallow heavy oil in Yajiao Oilfield is successful. It is necessary to select oil wells with low water cut and inject stronger steam to ensure thermal recoverv effect.
