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。 Sound field vibration, cavitation and thermal effects, can plug the pores and cracks in the particles spalling, so as to achieve the effect of blocking and microcracking. Sound field can also make the oil well anti-scaling, descaling, reduce the viscosity of crude oil, improve its seepage velocity. The thermal effect of the electric field can be reduced viscosity. Magnetic field can prevent wax, scale, by injection. These physical fields can each play an important role in oilfield development.
