摘要: 为解决以往油藏描述工作单孔资料在深度和广度上存在明显局限性的问题,提出了一套井震联合地质建模的方法:首先以地震精细解释的层位数据和断层数据为约束,结合测井资料建立构造模型;然后采用地震反演体的概率面在平面上作为约束,纵向上在测井曲线上分类统计各微相的概率分布曲线,在变差函数分析的基础上,采用序贯指示模拟算法模拟出储层微相的空间展布,建立沉积相模型;最后采用相控技术和地质统计学理论,分析参数区域化变量的特征,建立储层属性模型。在大庆萨尔图油田的B1DD区块进行验证的结果表明,井震资料的联合应用揭示了大量的小断层,使断点组合率提高了15%,大于2 m的砂岩预测符合率达到90%以上,提高了井间断层和砂岩的预测精度,进而提高了地质模型、尤其是井间模型的精度。

Abstract: In order to overcome the obvious limitations of the depth and breadth of single-hole data in previous reservoir description, the authors propose a method of well-seismic joint geological modeling. Firstly, based on the horizon data and fault data of fine seismic interpretation and combined with logging data,a structural model is established. Then the probability of the seismic inversion body is used to control the sedimentary microfacies, and the vertical probability distribution curves of each microfacies are classified and statistically analyzed. Further,based on the analysis of the variogram data, a sedimentary facies model is established through algorithm simulation of spatial distribution of microfacies. Finally, the reservoir attribute model is established by using facies control technology and geostatistical theory to analyze the characteristics of parameter regionalized variables. The verification results in the B1DD block of Salto oilfield in Daqing show that a large number of small faults are found through application of seismic data, the breakpoint combination rate is increased by 15%, and the prediction coincidence rate of sandstones over 2 m reaches more than 90%. The prediction accuracy of faults and sandstones between wells is improved, and the accuracy of geological models, especially the models between wells, is also improved through the application of this joint modeling method.

Key words: dense well network, joint seismic modeling, fault interpretation, variogram, Saertu oilfield
