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。 In this paper, the evolution and evolution of biogas and the characteristics of primary migration are mainly studied, and then the relationship between their formation and migration is explored. The study shows that biogas mainly migrates in two states and in two modes. The migration time of large-scale biogas is in the direction of buoyancy and residual pressure during the main gas-generating period, The favorable traps for short-distance migration.
