摘要：

针对塔中地区溶蚀孔洞型碳酸盐岩储层非均质性极强的特点,充分利用多种地震信息,高度综合地质、钻井、测井、地震等资料,将传统的“相控建模”思想引入碳酸盐岩储层建模当中,提出了溶蚀孔洞型碳酸盐岩储层建模新技术——“碳酸盐岩储集相控建模技术”。研究结果表明,该技术利用“碳酸盐岩储集相”和地震波阻抗反演数据体进行双重控制和约束,能有效增加模型的确定性,降低随机方法的多解性,显著提高储层建模的精度,是建立碳酸盐岩储层参数地质模型有效的建模方法。其建模结果与地质实际相符合,客观地反映了溶蚀孔洞型碳酸盐岩储层的严重非均质性,改善了碳酸盐岩储层三维地质随机建模方案,能为油藏精细描述、数值模拟、开发方案的制定提供合理的三维储层模型。

Abstract:

Based on characteristics of vast heterogeneity of carbonate karst and dissoled cavern reservoirs in the Tazhong area and integrated with full use of seismic, well logging, drilling information and geologic data, this paper applied the traditional “facies-controlled” concept into the modeling of carbonate reservoirs, yielding a new modeling technique for karst and dissolved carbonate reservoirs, “the facies-controlled carbonate reservoir modeling technique”. The study showed that this approach, constrained and controlled both by “carbonate reservoir facies” and by inversion data of the seismic-wave impedance, could effectively reduce modeling uncertainty and the ambiguity of randomicity, and improve modeling accuracy at maximum. Being an effective modeling method for the geological model of carbonate reservoir parameters, this approach was applied to the data of Well Tazhong-45. The modeling results matched well with the real geology by means of objectively reflecting the severe heterogeneity of carbonate karst and dissolved cavern reservoirs, improved the 3D-geology random modeling scheme for carbonate reservoirs. The accomplishment and output of this research is an important milestone of an effective 3D reservoir model for reservoir description, numerical simulation, development planning in a field with this type of reservoirs.
