Title
GAS RESERVOIR GEOCHEMICAL DESCRIPTION :METHOD AND APPLICATION
摘要
天然气轻烃指纹的测定一般限制在C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Jp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。
Abstract
Fingerprint testing of light hydrocarbons in natural gas has commonly been limited to C-C. 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.
