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.
