为探究太东地区油气的形成条件和油藏类型,通过二、三维地震资料精细解释,明确了该区的断层发育特征和构造格局,以层序地层学理论为指导,确定太东地区葡萄花油层等时地层格架。通过沉积微相研究,详细论述葡萄花油层各类沉积砂体的展布特征、发育规模。结合评价部署新资料,进一步明确太东地区葡萄花油层的成藏主控因素,得出研究区葡萄花油层具有超压间歇释放幕式运移的成藏模式以及油藏类型多样的结论,为斜坡带落实含油区提供了充分的依据。

This paper is an attempt to establish the development characteristics of faults and tectonic framework by fine interpretation on 2D and 3D seismic data,compartmentalize the isochron stratigraphic framework of Putaohua reservoir in Taidong region under the direction of sequence stratigraphic theory,and expatiate.The distribution and scales of all kinds of sand bodies of Putaohua reservoir based on the study on sedimentary microfaces.The paper details the controlling factors for hydrocarbon accumulation of putaohua reservoir in Taidong region,combined with data of new wells and concludes that the formation model of oil pool in Putaohua reservoir is characteristic of episodic oil accumulation driven by abnormal press and developing multi-type of oil pools.This study offers a basis for further exploration in Taidong region.
