摘要(Abstract)：

油田开发大体可分为开发前期、开发初期、稳定开采期、开发调整期、开发后期五个开发阶段,对处于不同开发阶段的油田,其可采储量评价方法也不同。大庆外围油田由于开发时间短,多数油田综合含水较低,因此,评价外围油田可采储量主要采用以下方法:标定采收率系列方法、经验公式法、经验图版法、实验室法、数值模拟法、水驱特征曲线法和递减曲线法。对于一个具体油田,由于受油田地质开发因素、油田所处的开发阶段及方法本身应用条件的制约,应用上述方法时会遇到一些问题。通过对大庆外围低渗透油田的可采储量计算方法进行评述,总结出一套外围油田可采储量预测原则,在应用中便于参考。
Oilfield development includes five development phases including development prophase,early production phase,stable production phase, development adjusting phase and development ana-phase. The ways evaluating the recoverable reserve vary from development phase of an oilfield. Because the production time is short and the composite water cut is relatively low for most of peripheral oilfields, the following methods are mainly used for evaluating the recoverable reserves for these oilfields, calibration recovery series methods, empirical formula method, empirical plate method , laboratory analysis method, numerical model method, water-flooding characteristic curve method and decline curve method. The above methods would meet some problems for a particular oilfield because it is limited by geological development factors, the stage in which the oilfield is being developed and the conditions for which these methods themselves are suitable. This paper set forth the above methods in detail and summarizes a set of forecasting principles for evaluating recoverable reserves of these peripheral oilfields.
