摘　　要：针对碳酸盐岩缝洞型油藏类型复杂且均质性强的特点,以“多类多尺度建模”为思路,引入“多方法结合、多概率融合”手段,提出多元信息融合建模方法。根据储层特征,分别对不同类型储层的地质建模进行研究。结果表明:以井震结合的方式确定性表征地下暗河储集体;以多点方法和基于目标方法相结合,融合断层控制发育概率和地震概率,建立断控岩溶储集体;以序贯指示方法,融合不整合面控制概率和地震概率,可建立溶蚀孔洞储集体;以蚂蚁体追踪方法可建立大尺度和中尺度裂缝模型;以基于目标方法建立小尺度裂缝模型,融合后的模型能够表征缝洞型储层的储集体分布特征,其储量复算和油藏数值模拟结果拟合度高,可作为开发方案的调整依据。The diverse types of reservoirs and strong heterogeneity require a combination of multiple modeling methods and probability aggregation to characterize the different scales of fractures and reservoir types.In this study,the deterministic modeling is used to characterize the model of underground river based on well and seismic data.The fault-controlled karst reservoir is established by combining the multi-point geostatistics method with the object-based method,where the fault and seismic attributes control the quality of the model.By using sequential indicator method,the dissolved cave model is established based on erosion surface and seismic attribute.The large-scale fractures and medium-scale fractures are acquired by seismic interpretation.The small-scale fracture model is established by the object-based method.The fused model characterizes the distribution of the reservoir by incorporating multiple information constraints.The reservoir numerical simulation results show high fitting accuracy with production data,which is helpful for adjusting the development plan.
