The hydrocarbon accumulation thresholds of all the hydrocarbon accumulation systems of two hydrocarbon accumulation assemblages are calculated based on hydrocarbon accumulation threshold theory.

滨北地区中浅层纵向上可以划分出2套成藏组合,即浅部成藏组合和中部成藏组合;每套成藏组合都可以划分出3个成藏体系,利用油气成藏门限理论对2套成藏组合的各成藏体系的油气成藏门限进行了计算,结合生油量的计算结果,对各成藏体系进行了定量评价。

The concept of hydrocarbon accumulation threshold (HAT) was built up on the basis of the study on pattern and mechanism of petroleum accumulation, and its discriminative equation was deduced.

对油气成藏模式和成藏机理进行了综合研究,提出了油气成藏门限的概念;建立了油气成藏门限的判别方程。
