摘要
流体在井筒中流动时,由于注入流体与地层存在温差,就有热量的传递。井筒传热量的定量计算显得特别重要,根据传热学和两相流原理,分析了环空注热污水加热降粘射流泵举升过程中注入水与产液沿井筒径向传热过程,采用传热学原理,对各部分传热系数的计算进行了推导。
When the liquid flows in a well bore, because there exists difference in temperature between injected liquid and formations, heat will transfer from the liquid to formations. The quantitative calculation of well bore heat transfer quantity looks particularly important. According to the theory of heat transfer and two-phase flow, the radial heat transfer process along the well bore for injected water and produced liquid in the lifting course of an annular injected heat polluted water reducing viscosity jet pump is analyzed. Using the theory of heat transfer, a deduction is carried out on the calculation of the heat transfer coefficients of each part.
