摘要: 在总结前人研究的基础上,推导出一种计算投入开发若干年后的油田(油藏)合理井网密度和极限井网密度的方法。该方法不仅考虑了投资、逐年管理费用和原油销售收入的利息,还充分考虑了注采井数比、剩余油分布、油田递减率等因素。该方法可对投入开发后的油田井网是否加密进行论证,使决策者最大程度地避免投资风险。

Abstract: Based on the previous studies available, a new method for calculation of rational well spacing density and ultimate well spacing density of a field or reservoir after development by water drive process for a number of years. This method not only takes account of the investment, overhead expenses per year and the interests of crude oil vendition income, but also considers the injection-to-production-well ratio, remained oil distribution and production decline rate, etc. This method can be used to demonstrate if the old field patterns are infilled or not for purposes of avoiding the risk of uncertain investment to the maximum.

Key words: water drive, water flood, well spacing density, recovery factor
