Abstract: A coordination between well pattern and the area of a sandbody in an oil reservoir was suggested in the previous work [l]. After that a production process optimization model [2] was formulated with performance index for improving oil recovery and economic benefits as their objectives. As its application and extension, this paper deals with the flow and stagnant conditions of remaining oil controlled by well pattern, as well as with a method of identification for the remaining oil uncontrolled by well pattern. As a result, a synergy among various conventional measures for improving oil recovery is suggested and some stimulating approaches adapted for a number of special type of oil formation and its related ideas are presented as well.

摘要： 井网与砂体大小之间的适应规律^[1],已经研究过;随后,以提高水驱采收率和改善经济效益为目标,提出了优化生产过程的最优控制法^[2].研究剩余油分布类型,是^[1,2]的应用和发展,研究井网未控制剩余油量的识别方法;研究井网已控制见水油层内剩余油的运动和滞留条件;在此基础上提出了挖掘生产潜力,常规措施,最佳协同运用方法.此外,还涉及了特殊类型油层挖潜的方向及有关的渗流力学概念.
