【摘要】 本文主要对生物气的生成演化模式和初次运移特征进行研究，进而探讨其生成与运移之间的相互关系。研究表明，生物气主要以两种状态赋存和两种方式运移，其大规模运移的时间是在主生气期内，运移指向是沿浮力和剩余压力的方向，由生气中心向附近的有利圈闭作短距离的运移。更多还原

【Abstract】 In this paper,thegeneration and evolution models and primary migration features ofbiogases are mainly studied,and then the relations between their generation and migrationare approached.The research indicates that biogases mainly have two inborn states andtwo migration patterns. The time of their large-scale migration is within their main gas-generating period.And their migration orientation is along the direction of buoyancy andresidual pressure. They make short-distance migration from gas-generating centres to fa-vorable traps nearby.更多还原
