Application of Blending Light Dropping Viscosity Testing Technology for Heavy Oil Well in Tahe Oilfield 稠油井掺稀降粘试油工艺技术在塔河油田的应用
The result show that chemical additives can reduce surface tension, when it reacts with oil in high temperature, light fraction in oil will be increased, viscosity of crude oil will be decreased and viscosity will not turn back. 根据试验结果,该化学添加剂能明显降低表面张力;在高温下与原油发生反应,增加原油的轻质馏分,使原油粘度降低,而且原油经过降粘后粘度不会反弹。
Field operation indicates that blending light dropping viscosity technique is a kind of main oil recovery one and stimulation for fitting Tahe Oil-Field ultra-deep level heavy oil. 现场运用表明,掺稀降粘工艺是一种适合塔河油田超深层稠油开采的主要采油工艺和增产措施。
