辽河坳陷潜山油气藏勘探近年来不断取得重大突破,实现了由寻找成藏条件相对明显的高、中潜山向寻找埋藏更深、更隐蔽、更复杂的低潜山和潜山内幕油气藏的勘探转变.从基底构造活动、潜山类型、岩性及储集层特征、生烃系统、输导体系等多角度探讨了低潜山和潜山内幕油气成藏条件;同时,考虑潜山内幕油气藏的特点,结合勘探实践,从潜山与油气的关系入手重新建立潜山内幕油藏实用分类方法,拓宽了潜山找油领域,形成了具有低幅度、多期裂缝、多油源充注特点的潜山内幕目标成藏模式.通过对辽河坳陷低潜山及潜山内幕油气成藏理论的研究与勘探实践,2001年至2006年,低潜山和潜山内幕累计上报三级储量分别达2.54×108t和1.76×108t,为辽河油田增储稳产作出了重大贡献.

Great progress has been achieved for exploration of buried hill reservoir in Liaohe depression. The exploration work for buried hill reservoir has changed from much distinct hill, such as top buried hill, middle part buried hill to much dee-per, blinder, complex buried bill, such as, lowly buried hill, inner buried hill. The reservoir forming conditions of lowly bur-ied hill and inner buried hill have been discussed considering factors of activities of basement structure, buried hill type, litholo-gy characteristic, reservoir characteristic, hydrocarbon generation system, passage system. A pragmatic classification for inner buried hill reservoir was updated, considering the characteristics of inner buried hill reservoir and exploration fact. The classifi-cation has expanded the areas of finding buried hill reservoir, and result to an objective accumulation model for buried hill reser-voir, with low amplitude, multiple stage fracture and multiple oil sources. From study and practice for exploration of low buri-al hill and inner burial hill in Liaohe depression, a discovery of low burial hill and inner hill reserves (containing proved oil re-serves, controlled reserves and predicted reserves) of 2. 54 × 108 tones and 1.76 × 108 tones respectively from 2001 to 2006 have been reached. It has a great contribution to development of Liaohe Oilfield.
