本文综述大庆油田小井距试验区进行的数值模拟研究工作，其中包括试验区动态的历史拟合、中心井控制储量计算和对采收率的校正。文中涉及到数值模型；等级三角形网格、地层参数插值法、拟相对渗透率曲线、流线图的计算和绘制、控制储量的确定等具体模拟方法；以及模拟结果的买际应用等方面内容。本文对总结交流数值模拟经验和进一步提高数值模拟工作水平是有益的。
This paper summarizes the numerical simulation of small well spacing in Daqing Oilfield, including historical dynamic fit of experimental area, calculation of controlled reserves in central well and correction of oil recovery. In this paper, we discuss some specific methods such as numerical model, hierarchical triangle mesh, interpolation of formation parameters, pseudo-relative permeability curve, calculation and drawing of streamline diagram, determination of control reserves, and the application of simulation results. This article is helpful to summarize the experience of AC numerical simulation and to further improve the numerical simulation work level.
