阿曼36、38区块油气勘探前景展望
|
摘要
阿曼36、38区块位于阿曼的西南部,面积3.6×104km2。该区在1953—2001年期间,由阿曼和西方的石油公司进行过油气勘探作业,完钻探井6口,有2口井在二叠系和志留系见到油气显示。由于前期勘探主要是针对志留系以上缺乏烃源岩的层系展开的,从而导致勘探效果不理想。根据重力、地震资料所做的新一轮地质评价认为,本区在海西运动之前与阿曼盆地沉积环境类似,也发育下寒武—前寒武区域上有利的生储盖组合,通过进一步的地质研究和勘探部署有望在区内发现古生界的潜在油气藏。
Block 36 and 38 locate in southwest part of Oman covering an area of 36000 km~(2).During 1953-2001,Omanani and some western petroleum companies conducted an exploration operation in this area.Six exploration wells were drilled,in which two had oil or gas shows in Permian and Silurian formation.Previous exploration mainly focused on strata above Silurian which lack of source rock,so the result was unsatisfied.New geological evaluation based on gravity and seismic data suggests that this area has a similar depositional environment to that of Oman basin before Hercynian event and favorable source-reservoir-seal assemblage was also developed in Lower Cambrian-Pre-Cambrian.So further geological research and exploration deployment may help us to find potential reservoirs of Palaeozoic in this area.
