摘要
针对目前递减率指标评价标准及评价方法存在的问题,首次引入状态对比法,将理论递减规律应用于递减率指标评价,建立了利用递减率评价系数来评价水驱油田递减率指标开发效果评价的新方法。该方法在应用过程中,考虑了流体性质、储层物性等的影响,可评价各开发阶段递减率指标的开发效果。该方法简单可行,可用于矿场水驱油田递减率指标的开发效果评价,具有较强的推广使用价值。
Aiming at the problems existing in the decline rate index evaluation standard and method, state contrast method is first introduced. Applying the theoretical decline to decline rate index evaluation, a new method for evaluating waterflooding effect by decline rate index is established. The method can reflect the influence of fluid properties, reservoir property and development phase on development effect. The applied results show that this method is simple and reasonable for evaluating the waterflooding effect by decline rate index.
