摘要:
稠油油藏自生CO2吞吐技术是一种新的增油方式。目前对该技术的研究多为增油机理分析,缺少油藏适应性的研究。通过数值模拟计算,应用正交试验,分析了含油饱和度、地层压力、储层渗透率和储层厚度4个主要参数对自生CO2吞吐效果的敏感程度,得出含油饱和度、地层压力、储层渗透率和储层有效厚度与自生CO2吞吐效果呈正相关,影响稠油油藏自生CO2吞吐效果的油藏参数顺序是:含油饱和度>储层有效厚度>储层渗透率>地层压力,其中含油饱和度对自生CO2吞吐效果影响分为三段,20%～35%之间属于弱敏感区,35%～45%属于高敏感区; 超过45%之后属于不敏感区。
Abstract:
Self-generating carbon dioxide huff-n-puff(SGCDH)for heavy-oil reservoirs is a new way to improve oil recovery. At present, there is a lot of research on the stimulation mechanism of the SGCDH technology, but few studies on the reservoir adaptability. By means of numerical simulation and orthogonal experiment, it was studied on the effectiveness of the SGCDH technology affected by four major parameters including oil saturation, reservoir permeability, formation pressure, and effective thickness of reservoir. The results showed that the oil saturation, reservoir permeability, formation pressure and reservoir effective thickness are positively correlated with the effectiveness of the SGCDH technology, and the four parameters affecting the effectiveness of the SGCDH technology in a descending order as the oil saturation, the reservoir effective thickness, the reservoir permeability and the formation pressure. And then the influence of oil saturation can be divided into three areas of weak sensitive(from 20% to 35%), high sensitive(from 35% to 45%)and nonsensitive(more than 45%).
