摘　　要：针对注蒸汽热力采油注汽阶段的特点,在借鉴前人研究成果的基础上,考虑流体相变和油层吸汽不均匀等因素,应用井筒多相流原理,建立了井筒配汽数学模型。在此基础上,应用实测资料对建立的配汽模型进行了验证。结果表明,实测值和计算值吻合较好,说明建立的井筒配汽模型能够较准确的解释注汽井的吸汽状况,从而反映井筒-油藏动态耦合规律。对目前注蒸汽热力采油过程的注汽动态具有很好的指导意义。Aimed at the characteristics of the steam injection stage of thermal recovery and based on the existed achievements, a relatively correct steam-distributed mathematic model is built in the paper. In this model, such factors as phase transition of fluids in wellbore and uneven inhibition of steam in formation are taken into account. Based on this research above mentioned, this model is verified by using actual testing data of several wells. It′s indicated that there exists a perfect match between the calculated values and testing data, which hints that the steam inhibition of the wells can be described with the steam distribution model established in this paper and the dynamic coupling law between the wellbore and formation can be reflected. The result of this research has guidance significance in the description of steam injection performance during thermal recovery of heavy oil.
