摘　　要：在储层反演中,要选择一条既能将储层与围岩区分开来又能与地震响应建立良好关系的测井曲线来重构储层、建立地质模型进行储层预测,这条曲线叫作特征曲线。根据平湖油气田开发区储层的特点,以及测井曲线的特征,提出用自然伽马曲线作为特征曲线,同时,详细叙述了选择特征曲线的理论依据和用特征曲线重构储层的过程,并用实际应用效果阐明了该方法的有效性和可应用性。During the process of reservoir inversion, a logging trace which can distinguish the reservoir from adjacent rock and have a good relationship with seismic response should be confirmed to rebuild the reservoir and build geological model so that we can make reservoir prediction, and this curve is called characteristic curve. In this article, the author analyzes the reservoir characteristic and the well logging curve feature of Pinghu Field and suggests using the gamma ray curve as the characteristic curve. At the same time, the author depicts the theory of choosing characteristic curve in detail and the process of reservoir rebuilt by characteristic curve. At the end of the article, the author clarifies the validity and applicability of this method by the actual application effect.
