摘　　要：南海珠江口盆地HZ地区碳酸盐岩广泛发育,碳酸盐岩储层非均质性强,纵、横向变化剧烈,导致常规建模反演方法预测碳酸盐岩储层不适用。针对碳酸盐岩储层的地质特点,对现有常规井插值建模反演方法进行了改进,以碳酸盐岩的沉积相信息和地震属性信息来约束建模反演,将不同尺度的沉积相信息、地震属性信息以及测井信息进行匹配融合建模,提出了适用于碳酸盐岩储层预测的相控多信息融合建模反演方法。研究结果表明,在研究区应用新的建模反演方法能有效提高碳酸盐岩储层预测的精度,该方法适用于非均质性强的碳酸盐岩储层。The carbonate rocks in the HZ area of the Zhujiangkou basin in south China sea are widely developed, the car-bonate reservoir heterogeneity in both vertical and horizontal is strong, which leads to the prediction of the carbonate reservoir is not applicable. According to the geological characteristics of carbonate reservoir, the existing conventional wells interpolation modeling inversion method was improved by deposition of carbonate phase information and seismic attribute information to con-strain the inversion modeling, the information of sedimentary facies and the different scales of seismic attribute information and logging information for matching fusion modeling, proposed fusion phase control modeling inversion multi information for car-bonate reservoir prediction. The research results show that the new modeling inversion method can effectively improve the ac-curacy of carbonate reservoir prediction, which is suitable for the characteristics of strong heterogeneity of carbonate reser-voirs.
