通过水与岩石表面接触角的测定、声被驱油实验和理论分析，研究考察了声波振动对原油─岩石、水─岩石界面特性的影响，从界面化学角度对岩石表面的润湿性和声波驱油机理进行了探索。结果表明：经原油浸泡后，由于原油中极性化合物（胶质、沥青质等）在岩石表面的吸附，岩石表面由水相润湿为主转变为油相润湿为主；无论岩石表面以水相润湿为主还是油相润湿为主，在水浸泡过程中，声波振动可促进其表面亲油性减弱和亲水性增强，毛细管阻力降低；伴随着岩石表面润湿性的改变，原油对岩石表面的粘附功明显降低；减弱了原油与岩石表面间的粘滞力，使原油更易于从岩石表面上剥离，提高原油采收率；岩石的渗透率越低，声波振动作用越显著。
Through the determination of the contact angle between water and rock surface, the sound was driven by oil displacement experiment and theoretical analysis. The influence of acoustic vibration on the interface characteristics of crude oil-rock and water-rock was investigated. The wettability of rock surface and acoustic wave Oil displacement mechanism was explored. The results show that after the crude oil is soaked, due to the adsorption of polar compounds (gums, asphaltenes, etc.) in the crude oil on the rock surface, the rock surface mainly changes from aqueous wetting to oil wetting; Water wetting or oil wetting, water immersion in the process, the sonic vibration can promote its lipophilic weakening and hydrophilic enhancement, capillary resistance decreased; along with changes in the rock surface wettability, crude oil Viscous force on the rock surface is obviously reduced; the viscous force between the crude oil and the rock surface is weakened, the crude oil is more easily peeled off from the rock surface and the crude oil recovery rate is increased; the lower the rock permeability is, the more obvious the acoustic vibration effect is .
