摘要
沈阳油田沈84断块原油的主要特点是高含蜡、高凝固点,低胶质和低沥青质含量。地层条件下原油粘度较低;油藏埋藏深,油层非均质性严重。针对本断块油藏及其流体特征,运用数值模拟技术,在建立非均质地质模型的基础上,进行了开采方式的优化研究。结果表明,采用注80℃热水段塞是改善这类油藏开发效果,提高采收率的有效途径。
The main features of the crude oil in fault block Shen 84 of Shenyang oil field are high wax content, high pour point, and low contents of gum and asphaltine. The viscosity of crude oil is low under the formation condition, the buried depth of reservoir is deep and the heterogeneity of reservoir is severe. According to this fault block reservoir and its fluid characteristic, using numerical simulation technique, based on heterogeneous geological model, optimal study of production scheme was carried out. The result shows that injecting slug of hot water of 80 ℃ is a effective method of improving the development result and enhancing the recovery of this kind of reservoir.
