摘要： 根据力学和物理化学的有关理论, 对油气初次运移问题进行了定量研究和分析。研究认为,油气是以连续相的形式从源岩运移到储集岩的。油气运移的动力是浮力和毛细管压力的共同作用。因油气初次运移为自然驱替,因此源岩的排烃效率较高。但油气的聚集和油气藏的形成,对源岩厚度有一定要求。

Abstract: According to the theory of mechanics and physical chemnistry, a quantitative study is conducted on the mechanism of primary migration of oil and gas. It shows that oil and gas moves fom source rock to reservoir mnck in continuous phase. The motivating farce of primary migation i the coalition of buoyancy and capillary pressure. The hydrocarbon expulsion efficiency of source nckprimary migation is usually high because of its propenty of natural drive. However, the hydrocarbon accumulation or reservoir formation requires some thickness of source rock.

Key words: crude oil, natural gas, primary migration, mechanism
