摘　　要：通过对低渗透窄小砂体油田目前面临的开发形势的分析 ,针对油田存在的主要问题 ,运用油藏工程方法、数理统计学方法及数值模拟方法 ,对油田在高含水期的主要开采技术政策界限进行分析 ,确定了主要开发指标的合理政策界限 ,分析预测了在“十五”期间的变化趋势 。After a low permeability and narrow sand-body oilfield enters high water-cut period, it will face with many problems, such as high water-cut, larger production decline and reserves-production disequilibrium, and so on. The limits of key development indexes, such as inferior boundary of oil well flow pressure, reasonable injection-production ratio limit, reasonable ratio of oil well number to water injecting well number, productivity index, injectivity index and the liquid hoisting limit in different water-cut periods, are presented by means of reservoir engineering method, mathematical statistics and numerical simulation, together with practical development. At the same time, the key factors of influencing the development indexes are analyzed. The limits of the indexes determined by using the mathematical models are consistent with practical situation, which shows the mathematical models of the development indexes set up in this paper are feasible. The mathematical models can be used to make out medium-long term developing programs and to predict development indexes for adjusting oilfield development programs. The research result in this paper provides effective scientific basis for oilfield development decision-making.
