Steam flooding is a method of injecting steam to heat the oil and decrease its viscosity so that it will be easy to flow from injector to producer. Fula North East oil field is a massive edge and bottom water reservoir with good properties and high viscosity of crude oil. As of March 2018, the oil field has been fully commissioned in steam stimulation for 3 years and the water cut rises rapidly and the oil rate declines seriously. In this paper, through comprehensive analysis of the geological properties of reservoir, production dynamics of single well and cement quality of wellbore, the steam flooding pilot test area under different well groups is screened out. Advanced thermal enhanced oil recovery simulator has been used to build the model of 279, 888 cells to design and optimize steam flooding pilot area for this field. The best well space and development program are optimized; this paper supplies a theoretical foundation for the next step of steam flooding in the whole field. The results show that the optimum steam flooding parameters for this area are steam injection temperature of 270 °C, with 5–7 MPa injection pressure, steam injection quality of more than 0.6 and steam injection rate of 1.6 m³/day/ha/m, and the final recovery ratio will reach 32.3%.

设计蒸汽驱先导试验模式的可行性研究和数值模拟

蒸汽驱是一种注入蒸汽以加热油并降低其粘度的方法，因此油很容易从注入器流向生产商。富拉东北油田是一个巨大的边缘和底部水库，具有良好的性能和高粘度的原油。截至2018年3月，该油田已全面启用蒸汽刺激服务3年，含水率迅速上升，石油价格严重下降。本文通过对储层地质特征，单井生产动态和井筒水泥质量的综合分析，筛选出不同井组下的蒸汽驱先导试验区。先进的热能强化采油模拟器已用于构建279、888单元的模型，以设计和优化该领域的蒸汽驱试区。优化了最佳油井空间和开发程序；本文为整个领域的下一步蒸汽驱提供了理论基础。结果表明，该区域的最佳驱油参数为注入温度为270°C，注入压力为5-7 MPa，注入质量大于0.6，注入速度为1.6 m。³ / day / ha / m，最终回收率将达到32.3％。
