指出自20世纪70年代以来西部凹陷一直是辽河油田的主要产区之一,已在该凹陷发现了欢喜岭、曙光、冷家堡、兴隆台等十几个油田,目前已经进入高成熟勘探阶段,原有的整装、易发现油气藏已基本勘探完毕,剩余的大多是隐蔽性较大的岩性油气藏,故而近几年在勘探上进展不大。认为从研究砂岩沉积特征入手、运用层序地层学和地震属性综合识别砂体的方法和确立构造与岩性并重的找油理念、总结老区规律、进行砂岩分布预测与评价,对于认识岩性油藏分布特征和勘探目标优选有着十分重要的作用。

The West Hollow has been one of the main producing regions of oil gas of Liaohe oil field all the time. Since the seventies, There have already found more than ten oil fields, such as, Huanxiling, Shuguang, Lengjiabao.etc. It has already entered high ripe exploration phase at present. This existing basically. The remaining is mostly the rock oil gas reservoir, leading to make little progress in exploring recent years. Therefore, in this study, begin with study sandstone deposit characteristic, using layers of preface stratigraphy, earthquake attribute discern sand body technological method, strengthening multi-disciplinary organic cooperation, establishing constructed and the rock as equally important in looking for the oil idea,summarizing the law of old liberated area, in order to predicted the distribute of sandstone. This is very important in carrying on the rock oil reservoir distribute characteristic and exploration target optimum.
