Abstract

A mathematical model of the transient temperature field of an oil reservoir after well start-up at a constant bottom-hole pressure is described taking into account the throttling and adiabatic effects. Two approximate solutions are considered and compared with the results of calculations of the thermal field using Ansys numerical simulator.

恒定压降模式下油井作业过程中的瞬态地层温度场

摘要

考虑节流和绝热效应，描述了油井在恒定的井底压力下启动后瞬态温度场的数学模型。考虑了两个近似解，并将它们与使用Ansys数值模拟器的热场计算结果进行了比较。
