摘要: 本文把地层与井筒考虑成一个连通系统,利用地层气体不稳定渗流数学模型,给出了计算气井失控井喷的原始地层压力、喷量、气体喷出总体积以及井底压力、地层内各点压力等参数的数学模型和方法,并用计算机对这些参数进行了数值模拟和求解。

Abstract: The formation and the wellbore are considered as an associated system in this paper. The mathematical model for calculating the parameters of formation pressure, gas blowout capacity, total gas volume erupted, bottom hole pressure and pressure in each point of formation etc. in a wild gas well has been proposed by utilizing the reservoir gas filtration mechanism in unsteady state.It s computer simulation method has been proposed and some meaningful data have been obtained.
