摘要
依据轻烃与环境作用的本质,可以把轻烃在自然界的赋存状态分为:游离态、溶解态、物理吸附态、化学吸附态及水合态。根据5种赋存状态轻烃在空间位置上的分布特征(体现在含量与组构上)就可以对对应地层及下伏地层的含油气信息进行识别与评价,5种赋存状态轻烃的组分及含量特征在我国相关油气藏上方都有丰富的石油地质意义。
According to the properties of light hydrocarbon in relation to environment,the modes of occurrence of light hydrocarbon can be divided into free state,dissolution state,physical adsorption state,chemical adsorption state and hydration state.Based on the distribution characteristics of light hydrocarbon of these five modes of occurrence which find expression in content and fabric,we can make discrimination and evaluation of corresponding strata and underlying strata.The composition and content characteristics of five modes of occurrence of light hydrocarbon contain abundant oil and gas information over all related oil and gas reservoirs in China.
