摘要
南海北部大陆架西区已发现的天然气(包括凝析油)可分三类:北部湾型、珠江口型(西部)和莺歌海型。这种分类是以其形成的地质背景、烃源岩、气藏特征及(油)气的地球化学性质等条件做为依据,并综合与油气生成密切相关的地质条件、主要烃源岩有机质的演化及其产物特征、TTI、泥岩压实等资料剖析了三类天然气的成烃史。
Gases (including condensate) discovered in western area of northern south China sea can be classified three types.They are a) BeiBu Bay type: b) Pearl River Mouth (western) type; c) Yinggehai type.The classification is based on their geological backgrounds,source rocks,characteristics of gas reservoirs and geochemistry properties of gases (oil) etc.Authers synthesize the data of geological conditions in closely relation to hydrocarbon origin,the organic matter evolution and products properties of main source rocks,TTI,and mudstone compaction etc.and analyse genetic history of three types of gases.
