油田某盆地历史油气成藏的特点研究

Characteristics of hydrocarbon accumulation in X basin of an oilfield

油田某盆地上古生界致密气藏含气层组多、面积大,存在多个压力系统,储集层非均质性强,具有先致密后成藏的特点,储量丰度低。

This article describes the characteristics of hydrocarbon accumulation in the upper Paleozoic tight gas reservoir in X basin of an oilfield,where exist multiple gas reservoirs and large areas,and many pressure systems. The reservoirs are in strong heterogeneity,which had become tight for hydrocarbon accumulation,the reserves are in low abundance.
