摘　　要：随着不断深入开发,油田集油管线内产液的流变性逐渐转变为高含水期“水包油”为主的流态,因而管道内的流动条件得以改善。通过前期开展的季节性停掺冷输试验证实,高含水期集输进站温度可以接近凝固点甚至低于凝固点。因此提出利用临界粘壁温度作为采油井不加热集输边界条件,并利用轮式动态模拟分析仪测试单井临界粘壁温度,指导采油井平稳集输,应用后实现措施节气219.6×10^(4)m^(3),节电73.4×10^(4)kWh。With the deepening development,the rheological properties of produced liquid in oil gathering pipelines have changed to the"oil-in-water"dominated flow pattern during the high water cut period,which makes the flow conditions in the pipeline be improved.Through the seasonal stop blending and cold transportation test conducted in the early stage,it is confirmed that the inlet temperature of the gathering and transportation during the high water cut period can be close to or even lower than the freezing point.Therefore,it is proposed to utilize the critical viscosity wall temperature as the boundary condition for unheated gathering and transportation of oil production wells,and use the wheeled dynamic simulator to test the critical viscous wall temperature of a single well to guide the smooth gathering and transportation of oil production wells.After the application,saving gas and electricity is 219.6×10^(4) m^(3) and 73.4×10^(4) kWh.
