| 摘 要： | 在实验室条件下,用超声波对多孔岩样的渗流速度进行了实验室研究。结果表明,超声波可使油对多孔岩样的渗透率增加一倍以上,使空气对多孔岩样渗透率提高18％。多孔岩样被泥浆、泥浆处理剂、搬土、橡胶颗粒等杂质堵塞后,经超声波作用,能使岩样减少堵塞、疏通孔道、减轻污染,使油的渗透率恢复到原来的61～88％,停止超声波作用后,还有明显的滞后效果。

| Abstract: | Laboratory studies of increasing flow rate in porous rocksamples by using ultrasonic wave were carried out. Under the action of ultrasonic wave, oil permeability was increased twofold and air permeability was increased by 18%. Ultrasonic treatment of rock samples contaminated by mud conditioner, drilling mud, bentonite, rubber particles could reduce plugging, relieve contamination and make pore space passable, with the permeability restored to 61-88% of its original value. The accompanying thermal effect of ultrasonic action also holped to reduce viscosity, thus facilitating fluid flow. Considerable after effect was observed after termination of ultrasonic action. |
