| 摘 要： | 设计用于油田开采防蜡技术中的两种永磁体磁场结构.一般地，好的磁场设计需具备两个特点：结蜡区内的磁感应强度强和油路轴向上磁感应强度的梯度大.为此，以Halbach型永磁磁场为基础，设计了两种“螺旋形”的防蜡磁场结构.通过数值模拟研究它们的磁场分布特点.结果表明：两种磁场均具备上述两个特点.

| Abstract: | Two strucutres of the permanent magnetic field have been designed for paraffin control in oilfield. Generally, the favorable design for such magnetic field meets the following two structural requirements. The magnetic flux densities in paraffin deposit zone in the cross-sectional direction are as strong as possible, and the gradients of magnetic flux density in the axial oil passage are as big as possible. Based on the concept of Halbach magnetic field, two structures have been designed and numerically analyzed to meet the above requirements for the purpose of the paraffin control. The results confirmed our conceivement and may serve as the application of the magnetic field construction for paraffin control in oilfield. |
