声场的振动作用、空化作用和热作用,可使堵塞岩孔和缝隙的颗粒剥落,从而达到清堵并产生微裂缝的效果。声场还可以使出油井防垢、除垢,降低原油粘度,提高其渗流速度。电场的热作用可以降粘。磁场可以防蜡、防垢、增注。这些物理场在油田开发中,可以各自发挥重要作用。

The vibration action,cavitation effect and heat effect of the acoustic field can flake off the grains to plug up the pore space and slit,and then remove the plugging and make the microfractures.The acoustic field can prevent and remove the scale,lower the viscosity of oil,enhance the seepage flow velocity.The heat produced by the electric field can reduce the viscosity.The magnetic field can prevent the wax and scale and increase the injection.Those physical fields play an important role in the oilfield development.
