摘　　要：针对塔河油田4区缝洞型碳酸盐岩储层非均质性极强的特点，充分结合地质、钻井、测井和地震等资料，借鉴传统的“相控建模”思想，用多点统计学储层建模方法，将储层赋予相的含义。根据地震属性与缝洞体之间的关系，由地震属性建立“储层相”的“训练图像”，采用SENSIM算法进行模拟，建立了储层相三维地质模型。结果表明，采用基于多点统计学的储集相控建模，既降低了缝洞型碳酸盐岩储层随机建模的不确定性，又显著提高了模型的精度，能够真实反映缝洞型储层的非均质性。In the light of the extreme strong heterogeneity of fractured-vuggy carbonate reservoirs in No. 4 Block of Tahe Oilfield and completely integrating the geological, drilling, well logging and seismic data and so on, the facies implication is presented to the reservoirs with the help of the traditional thought of ＂facies-controlled modeling＂ and the reservoir modeling method by multi-point statistics. Based on the relations between the seismic attributes and fracture-cavern body, the training image of the ＂reservoir facies＂ is established by the seismic attributes, SENSIM algorithm is adopted for the simulation, and 3D geologic model of the reservoir facies is built. The results show that the use of reservoir facies-controlled modeling based on multi-point statistics can not only reduce the uncertainty of stochastic modeling of fractured-cavernous carbonate reservoirs, but can significantly improve the precision of the model, so the heterogeneity of fractured-cavernous reservoirs can be reflected truthfully.
