兴隆台-马圈子地区沙三段浊积岩油气藏成藏条件分析

Analysis of Reservoir Forming Conditions of Turbidite Reservoir in Sha San Formation in Xinglongtai-Majuanzi Area

兴隆台-马圈子地区浊积岩油气藏一直是勘探的难点,多年来仍然未能取得明显的成效。通过对兴隆台-马圈子地区沙三段地层的基本地质特征、油气源条件、储层条件、生储盖特征及油藏特征等方面进行综合性分析,证实了兴隆台-马圈子地区浊积岩油气藏成藏条件十分有利,具有一定的勘探潜力和勘探前景,认识到储层分布与构造的相互关系是本区浊积岩油藏勘探获得突破的关键。

It has been very difficult to explore the turbidite reservoir in Xinglongtai-Majuanzi area. Despite of many years＇ practicing, no conspicuous results are obtained yet. This article studies the basic geological features, oil/gas source conditions, reservoir conditions, source-reservoir-cap rock association features, reservoir features and so on, which has demonstrated that the conditions of tur- bidite reservoir in Xinglongtai-Majuanzi area are very favourble for reservoir forming. At the same time, it has great exploration potentialities and prospect. The key to make breakthrough in exploring turbidite reservoir is to understand the relationship between reservoir distribution and structure.
