摘要： 正确确定稠油油藏的加热半径, 是油藏动态分析的关键, 是制定及调整开发方案的基础。作者从油藏生产实际应用出发, 从原油的流动系数入手, 利用原油的粘度与温度曲线方程, 在确定加热区前沿温度和井底温度的基础上, 给出了蒸汽吞吐开采油藏加热半径的动态计算方程, 并将加热半径与油藏原油流动系数联系起来, 认

Abstract: The correct determination of heating radius in viscous oil reservoi r is the key to analysing reservoir performance, and the basis for drawing up and adjusting development plan.Based on the flowing coefficient and the calcu- lated front and bottomhole temperatures in heating zone using viscosity-temperature curve equation of crude oil, the equation for calculating the heating radius is established.By relating the heating radius to flowing coefficient, it is suggested heating radius changes with time.
