大情字井葡萄花油层油气分布规律

Oil Enrichment Regularity of Putaohua Formation in Daqingzijing Area

由于葡萄花油层是大情字井地区非主力含油层系,重视程度和基础地质研究严重不足。为推进该层段的勘探开发,采用地震、地质、测井及试油化验分析资料的综合分析方法,提出不同类型油气藏的针对性识别方法和预测技术,总结油气平面和纵向分布规律。依此建立葡萄花油藏的油气富集模式,并直接应用于大情字井油田岩性油藏的勘探实践。

Due to Putaohua formation is non-essential reservoir in Daqingzijing area, less attention is paid on the basic geology research. Aim to boost the exploration development of the oil layer; a comprehensive analysis of the seismologic means, geology, logging and well testing is adopt. Meanwhile, the pointed recognition methods and forecasting techniques of different types of hydrocarbon reservoir are proposed. Finally, the horizontal and vertical distribution is concluded, and then the oil enrichment regularity of Putaohua formation is build up according to priority, which is directly used in the practical exploration of lithologic deposit in Daqingzijing area.
