The author makes the proposal of establishing a preliminary underground gas drainage numerical model, which is the equivalent of boundary conditions and shift forward of initial conditions.
本文从数值模拟的角度提出了建立井下瓦斯抽放数值模型的初步方案，即将边界条件等效和模拟时间前推。
The traditional model is not fit for some actual gas reservoir such as channel sand, which can be described as a box-shaped drainage volume.
传统模型对于实际气藏中如河流相沉积为主的储层则不适用，这类气藏更适合建立箱式封闭地层模型。
