考虑非平衡现象的稠油井井筒压力温度计算模型
摘要
Abstract
The concept of instantaneous equilibrium between oil and gas phase is often assumed when predicting wellbore pressure and temperature distribution. While for heavy oil wells, this hypothesis can lead to some errors. It has been proved through studying gas diffusion law in oil phase that there is a distinct non - equilibrium phenomenon in heavy oil wells. A calculation model of pressure and temperature for heavy oil wells has been derived with consideration of non - equilibrium effect based on the principles of mass, momentum, and energy conservation. It has been verified through case calculation that this model can accurately reflect the flow pattern in heavy oil wellbore and has certain engineering application value.关键词
