鄂尔多斯盆地北部古生代岩溶及有利油气勘探区块预测
PALEOZOIC KARST AND PREDICTION OF PROSPECTIVE SITES FOR PETROLEUM EXPLORATION IN NORTH ERDOS BASIN
【摘要】 从古岩溶风化壳分析入手,结合区内沉积岩相、古构造、地震及测井、岩溶角砾岩等的分析,指出古构造不仅控制着有利生储油(气)相带的展布,而且控制着古生代岩溶风化壳储层的生成、发展及时空展布,持续性主隆起是油气运移的指向地区,从而寻找出新的含油气区块。
【Abstract】 Based on Paleozoic karst weathering crust analysis and studies on sedimental lityofacies,paleostructure,karst breccia ,seismic event and well logging ,the authors have discovered that paleostructure controls not only the distribution of petrofacies favourable for oil(gas) accu-mulation but also the genesis,evolution and spatial distribution of reservoirs in paleozoickarst weathering crust.Continuously uplifting domes are areas showing the direction of oiland gas migration. Some new reservoirs can be found by using this result.
