摘要
油气藏不同部位的ΔＣ分布具有边缘井高于油井，油井高于干井的变化特征，但纵向上ΔＣ并不随梯度变化。因此在油气化探分析中，ΔＣ作为横向环境对比指标较为合适。
The distribution of C in different parts of oil and gas pools are different.The C in wells on the margins of the reservoirs is higher than that in oil wells,and the C in oil wells is higher than that in dry well.The variation of C is not related to the variation of buried depth.It is suggested that,in geochemical exploration,C could be used as the index of environmental correlation in horizental,but could not be used as vertical migration index.\;
