Seismic geological modeling study on S2 reservoir in ZD region

在ZD地区应用地震资料建立复杂断块油藏地质模型,是根据地震解释成果和断层平面组合关系建立断层模型,并以3D地震数据体对断层模型进行校正,以保证构造模型的准确性。采用相控建模的策略,以测井解释成果为硬数据,地震反演体为软数据,采用协模拟的方法进行储层参数模拟。研究发现,综合地震解释成果和3D地震数据体,有助于建立准确的构造模型,采用相控建模的策略,井、震结合进行储层参数模拟,有利于建立较为准确、合理的储层参数模型,为油田后期开发提供依据。

This paper presents a reservoir study in ZD field where seismic data have been fully utilized to obtain a better geological model of complex fault block reservoir. Using the fault point data and fault sticks,it can build fault surfaces, and examine structural surfaces and fault surfaces in 3D seismic. Using lithofacies controlled modeling,reservoir models can be created by well interpretation and seismic as correlated secondary variable. According to the research,we can find that accurate tectonic model is created by integrating the seismic interpretation and 3D seismic data. Using lithofacies controlled modeling, reasonable reservoir models are simulated by well log analysis and seismic inversion.
