Hydrocarbon migration has always been a nodus of hydrocarbon reservoir formation research.

对于油气运移的研究一直都是油气成藏研究中的要点.

Meanwhile, the sample contamination, oil - gas migration , multiple reservoir formation, mixed source, etc. should be noticed.

同时要注意样品污染 、 油气运移 、 多次成藏 、 混源等多种主客、观因素的影响.

However, the hydrocarbon accumulation or reservoir formation requires some thickness of source rock.

但油气的聚集和油气藏的形成,对源岩厚度有一定要求.

互联网

Therefore the properties of multiphase structural superposition and multistage reservoir formation are displayed.

形成了多期构造叠加、多期成藏的特点.

Transformation of tectonic framework plays a decisive role in all factors constraining on hydrocarbon reservoir formation.

构造体制转换在控制油气成藏中起着决定作用.
