摘要:

天然气轻烃指纹的测定一般限制在C8以内,在全烃色谱上可检测出55项参数,其中16项参数的聚类相关系数大于0.52,可作为天然气地球化学描述参数指标,判识天然气藏内部的分隔性和联通性。新场气田Jp15气藏依此指标,可划分出4个含气单元,目前,大多己知气田均分布于这些单元中。

关键词: 天然气藏, 轻烃指纹, 地球化学, 含气单元, 新场气田

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
