Abstract

Abstract:

The distribution of ΔC in different parts of oil and gas pools are different.The ΔC in wells on the margins of the reservoirs is higher than that in oil wells,and the ΔC in oil wells is higher than that in dry well.The variation of ΔC is not related to the variation of buried depth.It is suggested that,in geochemical exploration,ΔC could be used as the index of environmental correlation in horizental,but could not be used as vertical migration index.

Key words: oil and gas reservoir, ΔC, environment, migration index
