摘　　要：从储层厚度、渗透率、延伸长度、实进系数等指标评价南堡2-3区馆陶组(Ng)主力含油储层,指出单因素储层评价结果存在相互矛盾,不利于全面认识储层;运用灰色关联法分析,计算上述4项参数的权重系数,并采用权重法对储层进行综合评价。评价结果显示:NgⅠ4、NgⅠ6为Ⅰ类储层;NgⅡ5、NgⅡ6、NgⅣ为Ⅱ类储层;NgⅡ13、NgⅢ为Ⅲ类储层。分析了各类储层的特征,并利用动态资料证实了评价结果的可信度。The indexes of reservoir thickness , permeability , development area and anisotropy were evaluated in the Block NP 2-3 , it was pointed out that the results of single element evaluation were usually discrepancy.It was unbeneficial for overall understanding of reservoirs comprehensive.A gray correlation analyses was used to calculate the weight factors of the above parameters , The weight method was used for a Comprehensive Evaluation of the reservoirs in Block NP 2-3.The result show that the reservoirs NgⅠ4and NgⅠ6are the first class reservoirs , NgⅡ5 , NgⅡ6and NgⅣare the second class reservoirs and the reservoirs NgⅡ13and NgⅢare the third class reservoirs.The characteristics of each reservoir are analyzed , credibility of the evaluation result is proven with dynamic data.
