摘要
作者于1982年提出了油气初次运移量的计算公式并对几个盆地进行了试算。在本文中,作者进一步讨论了公式中各个量的物理意义,指出流体的排出量应当包括以下几方面的量值:压实作用造成孔隙度减小;埋深增加,流体比容增大;粘土矿物随埋深增加,发生转化;以及烃形成所导致的体积膨胀。并具体讨论了这些排液量的计算方法,以及在实际计算过程中其它各个物理量的取值和计算方法。
A certain formulae of Primary migration amounts of oil was developed and some calculations were done for a few basins in 1982. This paper discusses further the physical meanings of each parameter in the formulae, and proposes that expul-sion amount of fluid must consist of following parts; the amounts from porosity reduction by compaction, from increase of capacity of fluid with depth, from the transformation of clay minerals, and from volume expansion due to generation of hydrocarbon. It also discusses the calculation method of all these amounts and the selection of each parameter in the practice.
