高含水期地震约束储层建模技术

摘要
在油田高含水期,充分发挥地震资料和井资料分别在平面和纵向上具有高密度采样的特点,建立高精度的储层地质模型,是油藏开发领域的迫切需要。文中提出了利用高精度油藏地球物理储层预测成果为约束,建立高精度储层地质模型的方法理论。实例研究表明,地震约束储层建模方法能够发挥地质统计学对多学科专业知识的综合能力,有机地融合地震、测井和地质等信息,有效地降低地质模型的不确定性,有利于提高储层地质建模的精度,具有很好的实际效果和应用前景。
At high water-cut stage of development,it is necessary to build high precision reservoir geologic mo-dels by giving full play to the high lateral sampling density of seismic data and the high vertical sampling density of well data.In this paper,a new approach is proposed to build such a model constrained by results of highly accurate geophysical reservoir predictions.Case study shows that the seismic-constrained reservoir modeling approach can bring the advantage of geostatistics(i.e.,multidiscipline integration) into full play,effectively integrate sesmic,well log,and geologic data,and reduce the uncertainty of reservoir geologic models.The approach is proved to be effective in improving the precision of geologic models and have great application potentials.
