摘要: 东泼凹陷柳屯洼陷发育具有重力流性质的薄层状砂体,纵向上与灰黑色泥岩形成频繁互层,横向上砂体与盐岩对接,具有形成隐蔽油气藏的有利条件.笔者综合岩心资料、测井资料、地震资料和分析化验资料对柳屯洼陷胡96和胡108井区地质特征进行了研究,指出了该区隐蔽油气藏形成的地质基础.研究表明:该区烃源岩厚度巨大,发育扇三角洲砂体、水下冲积扇砂体和深水浊积扇砂体,储盖条件较好,盖层侧向封堵性较好,是形成隐蔽油气藏的有利地区.

Abstract: Subtle reservoir means various reservoirs that are difficult to be recognized and discovered by current exploration techniques. Thin-bed sandbody with gravity flow characteristics are developed in Liutun sag of Dongpu IOepression. It's interbedded frequently with greyish black mudstone in vertical section, sandbody and saline rock linkup with each other laterally, which exists favorable conditions forming subtle reservoirs. Based on core data, log-grog data,seismic data and laboratory analysis data,the authors study the geology characteristics of Hu 96 and Hu 108 wells area in Liutun sag and point out the geological basis of forming subtle reservoir. Study shows that hydrocarbon source rocks in the area are very thick where fanning delta sand body,alluvial fan sand body and deep-water turbidite fan sand body are developed. Conditions of reservoir and cap rocks are good. Cap rock lateral seal is good. This area is a favorable area for forming subtle reservoirs.

Key words: subtle reservoir, forming condition hydrocarbon source rock, reservoir rock, cap rock, Liutun sag
