摘要
采用储层地球化学研究方法,分析了崖13-1气田储层流体的非均质性,结合包裹体均-温度及源岩有机相分析结果,研究了崖13-1气田天然气的混源特征.崖13-1气田存在两种不同生源构成的"烃源灶”所生天然气以及不同成熟阶段所生天然气的混合作用.从南块3、6井区→北块4井区→北块1、2井区,天然气的"油型”(水生生物的贡献)特征逐渐减少,"煤型”(陆源输人物的贡献)特征逐渐增多,天然气的成熟度增高.
The reservoir geochemistry is used to analyse reservoir fluid heterogeneity in Yacheng 13 1 gasfield,and the mixed gas sources of the field are studied in combination with homogenization temperature of fluid inclusions and organic facies of source rocks.It can be concluded that there is a mixing of gases which derived from two different hydrocarbon kitchens and generated in various maturation stages in Yacheng 13 1 field.From the south block (3 and 6 well areas) to the north block (4 well area to 1 and 2 well areas),the gas shows a gradual decrease in features of oil prone organic matter (contribution of hydrobios), a gradual increase in features of coal forming facies (contribution of terrigenous sediment) and a rise in thermal maturity.
