泛河西走廊盆地群油气地质特征与勘探前景

泛河西走廊地区盆地群预测油气资源量为47.21×108t,具备优越的战略选区与深入评价的资源基础,但总体勘探程度较低,勘探程度差别大,资源探明率低。盆地群具有叠合盆地多层系勘探的地质基础,自下而上发育石炭系—二叠系、侏罗系、白垩系等烃源岩系,发育自生自储、下生上储等多类型、多套成藏组合,勘探目的层系在平面上呈规律性变化。泛河西走廓盆地群勘探研究中应:立足整体,类比评价优选重大接替领域,突出战略性;立足超前资源和技术储备,分析特殊性,突出前瞻性;着眼地质理论和关键技术,重视基础性;以风险目标优选与重大发现为主,兼顾风险性。

Petroleum Geology of Pan-Hexi Corridor Basins and Exploration Prospecting

The assessment of petroleum resources,including predicted and estimated resource,is more than 47.21 ×108t in Pan-Hexi Corridor basins,but the different exploration degree and low resource proved ratio is existed.Thus,the Pan-Hexi Corridor basins are selective strategic domains and abundant resources of petroleum.In the Pan-Hexi Corridor basins,distribution of basins is comparatively intensive,with large area for most of basins.If petroleum exploration would make a breakthrough,a large scale petroleum resource would be found.The exploration targets focus on the potential source rocks in Carboniferous-Permian,Jurassic and Cretaceous.There are effective multiply layers for petroleum accumulation in the Pan-Hexi Corridor basins.In the whole exploration,it should be paid more attention to predominant strategy,effective forecasting,foundational research basic and risk target.The strategic is to focus on the great replaced exploration domain,the forecasting is to restore of advancing resource and technologies,the foundational is to engage in geologic theory and key techniques and the risk is to eye on target selection for discovery of large scale petroleum field.
