Abstract:

Fingerprint testing of light hydrocarbons in natural gas has commonly been limited to C1-C8. 55 parameters have been detected from total hydrocarbon chromatogram, and clustering relation coefficient of 16 parameters has been calculated to be more than 0.52. 4 gas-bearing units have been determined with this indicator, where most proved gasfields distribute.

Key words: natural gas reservoir, light hydrocarbon fingerprint, geochemistry, gas-bearing unit, Xinchang gasfield
