摘　　要：准确预测蒸汽吞吐水平段加热范围对稠油油藏水平井的开发至关重要。鉴于目前中国已知的水平井加热预测半径公式中由于含有双重积分,使得计算过程比较复杂,需要消耗大量的时间。以马克斯-兰根海姆(Marx-Langeheim)直井加热范围公式为理论基础,并在此基础上进行了深入研究,将加热模型公式计算简化处理,推导出一个关系式简单、参数求解容易、应用方便的解析公式,在此基础上建立了水平井蒸汽吞吐简化加热模型,并应用油田实际参数对水平段加热面积进行计算分析,结果表明:应用改进的推导公式可得到相对可靠的计算结果,验证了公式的准确性。Accurately predicting period of heating steam stimulation area of horizontal well is very important for the develop-ment of heavy oil reservoir. The current forecast radius formula contains a double integral,which makes the calculating process complicated and time consuming. In this paper,by Marx Langenheim vertical well heating range formula as the theoretical basis,and on the basis of in-depth study,we simplified calculation of heating model,and established a simplified model of horizontal well cyclic steam heating,which is with simple relationship type,easy to solve and convenient to apply. Oilfield actual parameters are calculated and analyzed,and the results show that using the improved formula can get relatively accurate result,which verifies the accuracy of the formula.
