摘　　要：针对中国南海西部油田砂泥岩薄互层非均质性强、孔渗关系复杂的特点,应用核磁共振测井及成像测井数据,建立一种测试非均质砂泥岩薄互层渗透率的新方法。通过获得一定井段内的薄互层的有效储层厚度,可以鉴别储层类型,求取内在渗透率;通过分析已钻井的测井、地层测试和钻杆DST测试资料,证实了该方法的可靠性。该方法适用于裸眼测井之后的快速产能评价,对于探井或评价井,可以用最小的成本为作业者提供测试决策及射孔位置。Sand-shale thin inter-bedded layers of western oilfield of south China sea haves characteristics of strong heterogeneity and complex relationship of porosity and permeability,by using nuclear magnetic resonance(NMR)logging and imaging logging data,a new method of testing permeability heterogeneous of thin sand-shale inter-bedded has been established.By obtaining effective reservoir thickness of thin inter-bedded within a certain interval,the reservoir type and the intrinsic permeability can be identified and calculated.Through analysis of logging,formation testing and DST data of drilled wells,the method has proved to be reliable.The method can be applied to rapid capacity evaluation after open hole logging,and as for exploration well or appraisal well,the method can provide testing decision-making and perforation position for operators with minimum cost.
