| 摘 要： | 通过室内驱替实验及油藏数值模拟计算，描述了由于早期注冷水，致使油层温度降低，高含蜡高凝固点原油在油层孔隙中析蜡，对油层造成的冷伤害及其影响．数值模拟计算结果表明，注入冷流体的温度越低，则冷伤害程度越严重；地层渗透率越高，则冷伤害作用范围越大，冷伤害主要集中在近井地带，且随冷水注入时间的增长而加剧，但增加的速率逐渐减小

| Abstract: | The displacement test in laboratory and numerical simulation show that the reservoir temperature decreases, and the wax precipitates from crude oil of high wax content and high pour point due to the injection of cool water, which can result in the formation cooling damage. The cooling damage degree is influenced on the temperature of the injected water and the formation permeability. The lower the temperature of injected cooling water is, the stranger the damage will be. The higher the permeability is, the bigger the range of damage will be.The cooling damage exists near the well and become stranger with the increase of the time of injected cooling water. |
