【摘要】 碳酸盐岩油气藏在数值模拟的过程中往往缺少准确定量的裂缝模型,尤其是裂缝孔隙度和渗透率模型。文章从碳酸盐岩裂缝成因入手,对其构造裂缝进行预测;利用多元统计分析建立裂缝间距与构造主曲率值、岩层厚度及孔隙度之间的相关关系式,对井间未知区域裂缝间距变化进行预测,并在此基础上形成裂缝三维定量参数场。最后以麻柳场构造嘉陵江组气藏为实例验证了文中所提方法的可行性。该套方法为类似碳酸盐岩气藏建立精细裂缝三维定量参数场提供了理论依据。更多还原

【Abstract】 During the Carbonate gas reservoir’s numerical simulation process,it is often short of exact and quantitative fracture model,especially porosity and permeability models.Based on this condition,this paper predicts carbonate gas reservoir structural fractures according to its cause of fracture generating,and uses the multivariate statistical analysis to establish the correlative relation between fracture interval and reservoir thickness and porosity,which is able to predict the interval change in cross-hole area.Finally people apply this method in Jialingjiang gas reservoir and the results confirm its feasibility.This means provides theory gist for analogous reservoir forming the fine 3D quantitative parameter field.更多还原
