摘要
针对胡庆油田低幅度构造油藏和小断层遮挡形成的微构造油气藏等复杂小断块油气藏识别难度大,滚动勘探开发风险高的特点,基于地震、测井等资料,应用全三维地震构造精细解释技术、地震相干体断层识别技术、重复地层测试(RFT)和高分辨率地层倾角测量(HDT)综合应用技术,综合分析了东濮凹陷胡庆油田复杂小断块特征,形成了一套复杂小断块油气藏构造综合研究方法。该方法通过多资料、多技术的综合、集成应用,避免了单项技术的多解性,可以有效提高复杂小断块油藏的预测精度,从而降低勘探风险。
Huqing Oilfield is characterized by Low amplitude structure reservoir and the microstructure reservoirs formed by small fault block.Recognition of small complex fault block reservoir is difficult,and high risk exists in the rolling exploration and development.Based on seismic data and logging data,this paper analyzes the characteristics of small complex fault block in Huqing Oilfield of Dongpu Depression through the use of 3D seismic structure fine explanation technique,fault identification technique of seismic coherence cube and comprehensive application of RFT and HDT.A set of structure research methods of small complex fault block reservoir is summarized.This method avoids the ambiguity of single technique as a result of comprehensive application of mass data and multi-technique.This method can effectively improve the prediction accuracy of small complex fault block reservoir and can reduce the exploration risk.
