摘　　要：储层随机建模技术在碎屑岩储层中的应用较为广泛,而在碳酸盐岩储层中的应用则相对较少。针对建模工区面积大、钻井资料不足、地震解释资料不全、相控约束缺少、气水界面复杂等困难,提出了相应的解决方法,即属性模拟过程中利用储层厚度反演资料作为平面约束,两个气田采用不同的相关系数约束,储量计算中应用变气水界面。建模结果表明,目标碳酸盐岩工区的构造模型和属性模型的误差精度满足油藏描述需要,储量计算结果与传统容积法计算结果相当,可作为这类地质建模的一个参考。Stochastic simulation technique is always widely applied in clastic rock reservoir,but relatively few in carbonate reservoir.Facing many difficulties,such as large modeling area,limited interpretation data,no facies controlling and complex gas-water-contact,this paper proposes a proper solution to all problems mentioned above.Firstly,the inversion result of reservoir thickness is used as 2D restraint during property modeling.Secondly,different correlation coefficient is given in two different gas fields.Thirdly,variable gas-water-contact is generated in gas reserve calculation.The result shows that error precision of geological modeling fulfills requirements in reservoir description,and gas reserve calculation result is close to traditional volume calculation.The paper can provide a reference to similar geological modeling in carbonate reservoir.
