【摘要】：以裸眼完井水平井注过热型多元热流体为研究对象,通过引入过热型多元热流体各组分热物性参数实验数据,利用质量、动量和能量守恒方程,建立了裸眼完井水平井注过热型多元热流体传质传热模型。在模型验证的基础上,研究了非凝结气质量分数、注汽速度和注汽温度对热物性参数分布的影响。研究表明:随着非凝结气质量分数增加,井筒内同一位置流体温度和过热度均减小;随着注汽速度增加,井筒内同一位置过热度不断升高;跟端注汽温度升高,沿程吸汽量减少,过热度增加。模型对于矿场分析裸眼水平井传质传热规律、优选注汽参数具有重要指导意义。
[Abstract]:By introducing the experimental data of thermal properties of each component of superheated multicomponent thermal fluids, the conservation equations of mass, momentum and energy are used to study the injection of superheated multicomponent heat fluids in horizontal wells with open hole. A multi-element heat transfer model with overheated injection in open hole completion horizontal well is established. On the basis of model verification, the effects of mass fraction of uncondensed gas, steam injection velocity and steam injection temperature on the distribution of thermal physical parameters are studied. The results show that with the increase of mass fraction of uncondensed gas, the fluid temperature and superheat decrease at the same position in the wellbore; with the increase of steam injection velocity, the superheat in the same position of the wellbore increases; and the steam injection temperature at the end of the wellbore increases. The amount of steam absorption along the range is reduced and the superheat is increased. The model is of great significance for field analysis of mass transfer and heat transfer in open hole horizontal wells and optimization of steam injection parameters.
