Abstract

A model of non-stationary gas flow in the reservoir-well system was built with consideration of the heat transfer between the gas flow in the pipe and the environment of the gas flow, and solutions to boundary value problems were given. In the first approximation, the influence of change in the rheological properties of the gas depending on the temperature on the dynamics of the gas motion is determined. Analytical formulas were obtained for determination of the dynamics of pressure at the well bottomhole and the productivity of the reservoir depending on the parameters of the system. Numerical calculations were done for practical values of the system parameters.

受热传递的储-井系统气体运动

摘要

考虑管道内气体流动与气体流动环境之间的传热，建立了储层-井系统非平稳气体流动模型，并给出了边值问题的解决方案。在第一近似中，确定了取决于温度的气体流变特性变化对气体运动动力学的影响。根据系统参数，获得了用于确定井底压力动态和储层产能的分析公式。对系统参数的实际值进行了数值计算。
