胜利油田埕东-飞雁滩地区新近系馆陶组上段划分为1个三级层序、3个体系域、10个准层序组、23个准层序,层序界面、最大湖泛面、初次湖泛面和准层序界面控制了岩性油气藏分布。研究各级层序地层单元中的岩性油气藏分布特征,认为:岩性油气藏的分布与各体系域的特征相关,低位域和湖侵域砂体发育(高位域砂体不发育),故岩性油气藏发育,但低位域砂体缺乏良好封盖层,只发育小型油藏,而湖侵域砂体的封盖条件好,因此是岩性油藏主要赋存的层位;岩性油气藏的分布还受准层序的控制,如湖侵域中主要发育向上粒度变粗的准层序,而储集砂体分市于准层序的顶部,所以岩性油气藏主要发育于准层序顶部。图5参6 The Upper Paleogene of Guantao Formation in the Yingtong-Feiyantan area, Shengli Oilfield, is divided into three layers, including three quasi-sequence groups, three quasi-sequence groups, 23 quasi-sequence sequences, sequence boundaries, maximum lacustrine surface , The initial lacustrine and quasi-sequence interfaces control the distribution of lithologic reservoirs. The distribution characteristics of lithologic reservoirs in sequence stratigraphic units at various levels are studied. It is concluded that the distribution of lithologic reservoirs is related to the characteristics of each system tract, and the sand bodies in the low-level and lake-intrusion reservoirs are not developed. Therefore, the lithologic reservoirs developed. However, the low-level sand bodies lacked a good capping layer and only developed small reservoirs. However, the cap-sealing conditions of the sand invaded by the lake were good, so they were the main reservoirs of lithologic reservoirs. The rocks The distribution of sex reservoirs is also governed by quasi-sequence, such as the quasi-sequence, which mainly develops upwards grain size in the lake intrusion, while the reservoir sand body is located at the top of the quasi-sequence, so the lithologic reservoir mainly develops At the top of the quasi-sequence.
