摘　　要：针对辽河油田资源接替紧张和油田勘探开发形势不容乐观的局面,通过对辽河盆地深层烃源岩、储层、盖层、圈闭以及运聚条件等成藏要素的综合分析,认为深层油气成藏条件较好。辽河盆地资源潜力分析表明,其深层资源量相当丰富,石油地质储量为10.04×108t,天然气储量达3.65×1011m3,虽然探明程度较低,但勘探前景好。深层是该区可持续发展的最现实的勘探领域,而岩性油气藏则是深层勘探最有利的目标。With resources substitution becoming more and more serious,exploration and development situation in Liaohe Oilfield cannot be optimistic. Key elements for the hydrocarbon accumulation conditions of deep horizon are comprehensively analyzed,including the conditions of source rocks, reservoirs, cap rocks, traps and the collocation of hydrocarbon transportation and accumulating conditions. It shows that the hydrocarbon accumulation conditions are very favorable. According to the evaluation of resources potential of the deep horizons,the resources of the deep horizons in Liaohe Basin are extremely abundant. OOIP is 10.04×108t,and natural gas reserves are up to 3. 65×1011m3. Owing to its low exploration level,the deep horizons have a better exploration perspective. The deep horizons are the most tangible prospecting field for Liaohe Oilfield to realize sustainable development in current situation, and the lithologic reservoirs in the hydrocarbon generation depression are the most beneficial exploration object for the deep horizons.
