Abstract为了研究润湿性反转荆对渗流过程的影响,对润湿性反转剂的微观渗流机理进行了研究。用接触角法和Washburn法测定了固体表面的接触角,研究了润湿性反转荆对润湿性的影响;用界面张力仪测定了润湿性反转荆的油水界面张力,分析其降低油水界面张力的能力;并用微观刻蚀模型驱油试验研究了润湿性反转荆的微观渗流机理。试验结果表明:润湿性反转剂能改变表面的润湿性,使亲油表面变为亲水表面;润湿性反转荆有降低油水界面张力的能力,能使油水界面张力降低至10^-1mN/m;润湿性反转荆使油膜剥离并形成油桥,使润湿性反转。该研究说明油水界面张力和润湿性都影响油水渗流特征,为进一步研究如何改善油水渗流过程奠定了基础。
