摘要(Abstract)：

结合二连盆地赛汉塔拉凹陷的勘探实践,阐述了赛东洼槽岩性地层油气藏形成的有利条件。按照"下洼寻找岩性油藏"的勘探思路,通过资料重新处理、老井复查、应用层序地层学方法进行层序划分和沉积体系研究、精细储层地震反演等技术攻关的研究表明,赛东洼槽烃源岩发育,具备形成岩性地层油藏的有利沉积构造背景,具有很大的勘探潜力。腾一段顶部和腾二段底部储层成藏条件好,是赛东洼槽内寻找岩性油藏的主要目的层。
Integrating the exploration practice of Saihantala Depression in Erlian Basin,the paper describes the favorite forming conditions of lithological petroleum reservoir in Eastern Sag.According to the exploration thoughts of"seeking for lithological oil reservoir in lower sag"and with the help of data reprocessing,old well checkout and sequence stratigraphic method,sequence classification and sedimentary system study have been carried out.The studies of technical innovation including fine seismic inversion of reservoirs and so on show that the source rock in above sag is well developed and has the favorite sedimentary structure's background to form lithological oil reservoir,so it possesses a great exploration potential.As much better reservoir-forming conditions exist at the top of Teng No.1 interval and in the bottom of Teng No.2 interval,so they can be main target layers of lithological oil reservoir in Eastern Sag.
