摘　　要：通过采用径向电阻率比较法、自然电位基线偏离法、自然电位与电阻率结合法、碳氧能谱与中子俘获测井等多种方法相互结合定性识别特高含水库姆克尔油田水淹层;并且利用C/O能谱测井与中子俘获测井计算含水饱和度,运用可动水饱和度和产水率划分水淹强度并对水淹层量化;依据水淹层解释的结果并结合水淹类型,对全油藏水淹层的平面展布及强度进行论述,同时从沉积微相、构造、注水强度和采液强度对水淹影响因素进行分析。依据水淹情况综合分析,确立了剩余油分布的特征,选定了下步挖潜的方向。By using a variety of methods,include radial resistivity contrast,SP logging baseline deviation,C / O,neutron capture logging,to recognize qualitatively the water-flood reservoir in high water cut Kumkol oil and gas field. And the use of the C / O and neutron capture logging for calculating the water saturation,and the use of movable water saturation and Fw divided water flood intensity and water flooded layer quantification. Based on flooded layer interpretation the results of combined flooding type,distribution and intensity of the plane of full reservoir flooded layer are elaborated,and from sedimentary microfacies,structure,injecting water intensity and mining liquid water intensity,the flooding factors are analyzed. Based on a comprehensive analysis of the flooding situation,the features of residual oil distribution are established,and the direction of tapping the potential in future is selected.
