摘要

摘要: 周口坳陷石炭—二叠系煤系地层有机质较丰富,含煤性好,岩性岩相稳定,具有较强的生烃潜力.二次生烃是其显著特征,二次生烃量大小受源岩初始成熟度、生烃潜量和终点成熟度的制约.坳陷内二次生烃条件相对较好的是谭庄—沈丘凹陷和倪丘集凹陷,并已在倪丘集大王庄构造南12井下第三系获得过源自石炭—二叠系的工业油流,展示出该区煤成油气勘探前景广阔.

Abstract: The Carboniferous-Permian coal measures strata in the Zhoukou Depression have stronger hydrocarbon-generating potential, which process abundant organic matter, rich coal and steady lithology and lithofacies. The obvious character of the depression is secondary hydrocarbon generation. The amount of secondary hydrocarbon generation depends on initial maturity, hydrocarbon-generating potential and final maturity. The places which have better secondary hydrocarbon-generating potential in the Zhoukou Depression are the Tanzhuang-Shenqiu Sag and the Niqiuji Sag. The industrial oil flow was obtained from the Paleogene of well Nan-12 at the Dawangzhuang Structure in the Niqiuji Sag, It indicated that the exploration prospects of coal-derived hydrocarbon in the area was extensive.
