摘　　要：储层三维地质建模即在三维空间上表征储层的各项地质特征,是油气藏勘探开发过程中揭示储层特征、寻找有利目标的基础。针对四川盆地龙岗气田鲕粒滩型碳酸盐岩储层非均质性强且研究区井网密度小等特点,形成了以单井解释数据为硬数据,地震属性体资料为约束,高度综合地质、钻井、测井、地震等资料的碳酸盐岩相控储层建模技术系列。该方法将纵向上小尺度精细井资料与地震资料高横向分辨率的优势有效结合,增加了井间预测的合理性,提高了地质模型的精度。建模结果再现了油藏三维空间展布特征,为油田详探、制订和调整开发方案提供了重要依据。The 3D geologic reservoir modeling is used to characterize the geologic characteristics of reservoir in three dimensions, and it provides the basis for revealing reservoir characteristics and searching for favorable targets in the process of exploration and development. In the Longgang gasfield, the Sichuan Basin, oolitic-beach carbonate reservoirs are strongly heterogeneous and the well pattern density of the study area is low. In view of these characteristics, a series of facies-control carbonate reservoir modeling technologies were developed with individual-well interpretation data as the hard data and seismic attribute volume data as the constraints. These technologies integrate geologic, drilling, logging, and seismic data. With this method, the advantage of small-scale vertical fine well data and the high lateral resolution of seismic data are combined effectively to improve the inter-well prediction rationality and the geologic model accuracy. The three-dimensional distribution characteristics of reservoirs are reproduced by the modeling results, thus providing a valuable basis for the detailed prospecting, formlation and adjustment of development plans.
