【摘要】 为进一步明确潜江凹陷潜江组四段下亚段(E2q4L)的勘探潜力,利用钻井及地震资料,从沉积充填、储集条件、烃源条件和油气成藏等方面开展系统研究。结果表明,E2q4L具有良好的烃源条件,具有自源自储和自源它储两大成藏模式,形成两大勘探领域,一是自源砂岩油藏勘探领域,二是以E2q4L为烃源层而其上地层为储集层的它源油藏勘探领域。更多还原

【Abstract】 In order to clarify the exploration potential of E2qL4 reservoir exploration in Qianjiang Depression,drilling and seismic data were used for a systematical study on sedimentary filling,reservoir condition,hydrocarbon source condition and hydrocarbon accumulation.The results show that E2qL4 reservoir has good hydrocarbon source condition,has two major patterns of accumulation from the reservoir source and source storage,by which two major exploration areas are formed,one is from the reservoir sandstone,the other is that E2qL4 as the hydrocarbon source rock and the reservoir above the source layer.更多还原
