| 摘 要： | 轮南油田属于超深碎屑岩油藏,目前主要采用稀井网,以天然能量和水驱开发为主,尚未形成三次采油,其地质油藏特征(埋藏深、地层温度高、地层压力高、地层水矿化度高、原油黏度低)决定了注天然气是其三次采油的现实方向。通过细管实验、长岩心驱油实验和在现有组分模型基础上提取局部地质模型,数值模拟计算连续注天然气波及系数为48.75%,提高采收率10.72%,明确了轮南油田在目前水驱剩余潜力较小的情况下,注天然气开发具有较大潜力。

| Abstract: | Lunnan Oilfield is an ultra-deep clastic sandstone reservoir. At present, the approach of rare well pattern dominated by natural energy and water flooding development is mainly used, and a recognized way of tertiary oil recovery has not been developed. Furthermore, some geological reservoir characteristics of the oilfield including high temperature, high pressure, high salinity, and low oil viscosity determine its unique EOR method. Through a tube experiment, long core displacement experiment and on the basis of the existing component model to extract local geological model, we got the continuous gas injection sweep efficiency being 48.75% and recovery was enhanced by 10.72%, based on numerical simulation. It was confirmed that gas injection development had great potential in the context of smaller residual potential by water flooding in the oilfield. |
