测井曲线标定有机碳方法在苏北盆地的应用

测井曲线标定有机碳技术方法是一种不同于传统地球化学测试得到的有机碳方法，它根据烃源岩内有机质的含量在测井曲线上具有一定的特征响应，通过地球物理测井手段鉴别与提取这些特征属性，再利用测井曲线标定的有机碳含量关系式进行计算，从而得到准确的有机碳含量。这种方法既简便易行又准确可靠，与传统地球化学测试得到的有机碳方法具有良好的对应性。通过对苏161井阜四段、苏169井阜三段烃源岩测井标定有机碳含量与实测值的对比性研究，表明在苏北盆地用测井资料计算的有机碳来补充取心资料的不足，从而对该地区地下油气进行分析具有切实的可行性和较好的适用性。

Organic Carbon Demarcating Method with Well Log and Its Application in North Jiangsu Basin

Organic carbon demarcating technology with well log is an organic carbon gained method different from the conventional geochemical testing.According to the certain characteristic response on the well log for the organic matter content within the hydrocarbon source rocks,and these characteristic attributes are discriminated and picked up by geophysical well logging,and the relation formula of organic carbon content demarcated by well log is used to conduct the calculation,thereby the accurate contents of organic carbon are obtained.This method is simple,easy,accurate and reliable,and of fine parallelism with the results tested by conventional geochemical testing method.Based on Well 161 of Block four in Funing formation and Well 169 of Block three in Funing formation,a parallel study is conducted for the organic carbon content demarcated with well log of hydrocarbon source rocks with the measured content value of the organic carbon.It is concluded that the organic carbon calculated by log data can make up the deficiency coring data in North Jiangsu,thereby the organic carbon method is of practical feasibility and preferable applicability in oil and gas analyses for North Jiangsu.
