This paper make water cut heavy oil in liaohe oilfield ground gathering and transportation engineering as the research object, using microwave heating and non-thermal effect on crude oil, design and build the heavy oil pipeline ground microwave heating gathering and transportation indoor experiment device. Through the indoor experiment, study the microwave viscosity reduction and dehydration effect on particular heavy oil, select the microwave optimal heating frequency and heating power. The experimental results show that this method has obvious advantages of fast heating and energy saving compared with the traditional gathering and transportation heating.
