为了合理分配和利用水平井热采过程中注入的能量,增加采出程度,对影响水平井段的传热传质因素进行分析是非常必要的。针对水平井井筒与油藏之间的传热与传质问题,利用水平井的热工水力学模型,对济阳坳陷草桥油田的热采水平井进行模拟。根据模拟结果,分析了沿水平井井长方向上的热量分布和动用储量分布、水平井在油藏的不同位置对盖层的热损失和油藏加热状况的影响,提出采取不同的射孔方案等方法来解决长水平井段的传热传质不均匀问题。
In order to rationally allocate and utilize the energy injected during the horizontal well thermal recovery process and increase the recovery rate, it is necessary to analyze the factors that affect the heat and mass transfer in the horizontal well section. In view of the heat and mass transfer problems between horizontal wellbores and reservoirs, the horizontal well thermal-hydraulic model was used to simulate the thermal recovery horizontal wells in Caoqiao Oilfield, Jiyang Depression. According to the simulation results, the distribution of heat distribution along the length and length of horizontal well, the distribution of available reserves, the influence of horizontal wells on the thermal loss of cap rock and reservoir heating status in different positions of reservoir are analyzed, and different perforation schemes And other methods to solve the problem of uneven heat and mass transfer in long horizontal section.
