摘　　要：通过对垂直井、斜直井井筒温度分布规律的研究，推导出水平井注蒸汽热采时井筒温度分布的理论模型，并进行了解析求解，依据油品性质（包括地层热物性参数），计算出了不同产量、含水量，不同油层条件下的井筒温度分布，从而确定出油井在不同条件下的加热深度。Through study of distribution pattern of wellbore temperature in vertical and deflecting vertical wells, this paper derives a theoretical model of temperature distribution in wellbore during the period of thermal recovery of steam injection in horizontal wells, and gaves the analytic solution. According to crude properties (including formation thermophysical parameters), wellbore temperature distribution of different production, different water content and different oil reservoir is calculated, thereby the heating depths of oil wells under different conditions are determined.
