【摘要】 叠合盆地复杂的演化历史给老烃源岩系生烃、成藏规律和资源潜力研究带来了困难。丰富有效的烃源岩、超晚期的“二次生烃”过程、相对较好的储集条件、继承性隆起的构造部位和有效的封盖层,是形成上古生界自生自储油气藏必备的苛刻条件。石炭-二叠系原型盆地解体后,在周口坳陷中部坳陷带和北部坳陷带的中、新生代深凹区不同程度地残存有石炭-二叠系。倪丘集凹陷和潭庄-沈丘(东部)凹陷的上古生界烃源岩在中三叠世末(一次生烃)时的有机质热演化程度低,在喜山期再次深埋中保持了较强的“二次生烃”潜力,为成藏创造了基础。本文提出了立足于超晚期成藏、充分考虑烃源岩“二次生烃迟滞效应”的叠合盆地老烃源岩系勘探前景评价思路。更多还原

【Abstract】 The complicated evolution history of complex basin leads difficulties in the study of hydrocarbon generation,oil reservoir rule and resource potential appraising course.Rigorous factors of Paleozoic Erathem inner pool forming include abundant source rock,aftermost quadric hydrocarbon generation progress, relatively better reservoir quality,successive uplift and effective caprock.Remanet Carboniferous-Permian system only existed in Mesozoic and Cenozoic sags of center to north depression section of Zhoukou basin.Paleozoic source rocks in Niqiuji and Tanzhuang-Shenqiu(east part)sags had relatively strong quadric hydrocarbon generation potential in Himalayan,because of their lower maturity in Triassic(the firs hydrocarbon generation period).This paper gave the method of exploration prospect evaluation for Paleozoic source rocks in view of aftermost refilling and delay maturity of quadric hydrocarbon generation.更多还原
