摘要
针对我国部分油田高含水期开发的实际情况，采用超声技术成功地配制了原油超声乳状液，并进行了乳状液段塞驱油试验，试验表明，超声乳状液能够在水驱油的基础上进一步提高原油的采收率，降低产出液的含水率，超声乳状液具有不加化学药剂、配制简单、稳定性好等优点，适用于高含水期油田的进一步开发．
On the fact of oilfield development in the stage of high watercut in some oilfields of China, ultrasonic-emulsions were prepared by using ultrasonic technique. Experiments on oil displaced by ultrasonic-emulsion slug were carried out. The results show that ultrasonic-emulsion slug can increase oil recovery and decrease the producing water-cut. The preparation process of ultrasonic-emulsion is simple. The ultrasonic-emLilsion is stable and available for the development of oilfield in the stage of high watcr-cut.
