摘　　要：塞云-马西拉盆地是在晚侏罗-早白垩期也门境内发育的裂谷盆地。存在以侏罗系Meem组为源岩的已证实的含油气系统,发育六套储层,四套盖层。预测存在六类成藏组合,Qishn组背斜-断块成藏组合和基底断块成藏组合是盆地主要的成藏组合。该成藏组合广泛分布在盆地各个构造单元,目前已发现油田集中在马西拉地堑带,含油高度大,油质轻,储量规模大。近两年在盆地西部基底裂缝有了突破性发现,预示着十分良好的勘探前景。基底油藏勘探程度相对较低,勘探潜力大,将是盆地今后储量增长点。Sayun-Masila basin is a rift basin developed in Yemen in late Jurassic-early Cretaceous.A petroleum system sourced from Meem formation of Jurassic is proved.There are six sets of reservoir rocks and four sets of cap rocks in the basin.Six play concepts are predicted as well.Anticline-fault block and basal fault block are the primary play concepts which spread widely in the basin.Oil fields discovered in the basin are mainly in Masila graben belt and produce light oil with massive reserves.Discovery of basal fissures indicates good prospect of exploration.Basement reservoir has a low degree of exploration but with considerable exploration potential,which plays an important role in future reserves increasing.
