摘要
针对某高凝油油藏原油含蜡量高、析蜡点高、凝固点高和原油物性对温度敏感的特点,根据石蜡沉积油层孔渗伤害大、注常温水使得渗流规律发生变化等开发现状,依据油藏参数建立数值模型,采用数值模拟方法研究不同注水温度、不同注水量、不同井网对温度场分布规律的影响,最终确定合理的注水参数。研究结果表明,最佳注水温度为66℃,注水量为600m3/d,最优井网为五点井网。
Aming at the development status of one high pour - point oil reservoir having high wax content, high wax precipitation point and freezing point, temperature sensitive of oil property, and the changes of seepage law as well as the large damages caused by the injection of room temperature water, etc. , the influence of water injection having different injection temperature, injection rate and well spacing on the temperature field distribution was studied by using the reservoir numerical simulation model to determine the reasonable water injection parameters. The results showed that the optimum water injection temperature is 66℃ ,injection rate is 600m3/d, and the optimum well pattern is five - spot well network.
