新站油田葡萄花油层油藏成因及保存条件研究

A STUDY ON THE RESERVOIR GENESIS AND THE PRESERVE CONDITION OF PUTAOHUA RESERVOIR IN XINZHAN OIL FIELD

从研究新站油田葡萄花油层的垂直裂缝系统分布、油藏压力梯度分布及油水分布的关系入手， 在深入研究油藏的异常压力成因、断层及垂直裂缝系统形成期的基础上， 根据油藏的成藏时期与断层及其垂直裂缝形成、活动时期的先后关系， 分析不同时期形成的断层及其裂缝系统对油藏的影响， 从而归纳出油水分布的规律性， 指导整个新站油田的评价与开发。

This paper studies the relation among vertical fracture system, reservoir pressure gradient and oil and water distribution of Putaohua Reservoir in Xinzhan Oil Field, and then studies the genesis of abnormal pressure and the formation period of faults and vertical fractures system of the reservoir. According to the successive relation between the reservoir forming period and the formation and movement period of the faults and the verticle fractures, it analyzes the effect of faults and their fractures system formed in various period on the reservoir, summurizes the rule of oil and water distribution, and guide the evaluation and development of the whole Xinzhan Oil Field.
