济阳坳陷下古生界潜山内幕油气藏勘探

针对济阳坳陷下古生界以凤山一冶里亮甲山组为主的潜山内幕油气藏勘探的实际情况，从油源、储层、油气运移通道、配置关系及压力平衡等角度对潜山内幕油气藏成藏条件进行了分析。认为，对该套地层应在充分考虑潜山的地质结构、沉积体系、油气生排时期的压力以及生油层和储集层的埋深关系等基础上，有目的地进行勘探。

Exploration on internal pool of buried hill in lower Palaeozoic group of Jiyang Depression

Aiming at practical situation of internal pool exploration of buried hill in the major Fengshan -Yeli -Liangjiashan formations of lower Palaeozoic group of Jiyang Depres- sion, pool -forming conditions, such as oil source, reservoir, migration passages, collocated relation, pressure balance, are analyzed systematically. The research shows that geological structure, sedimentary system, pressure at the stages of hydrocarbon generation and expulsion, and relation between the buried depths of source bed and reservoir should be considered sufficiently during exploration.
