摘    要:通过大量生产数据分析与计算,建立了萨地中地区各套系合理注采比预测模型,萨中全区合理注采比预测宜采用注采比与水油比法,萨葡层宜采用物质平衡法,高台子宜采用多元回归法,根据预油公司可得出一定似设条件下(定产,定压和定含水上升速度)今后两至三年注采比较变化规律,数模计算结果与注采比较件拟合结果基本吻合,表明本项研究建立的数学模型是可靠的,依据理论分析计算,给出一次,二次加密调速井及基础井网,确定了合理的注水匹配关系,提出了调整注采比和注采结构的建议,在生产实践中收到了较好效果。

关 键 词:地层压力  水油比  注采比  数学模型  注采结构调整  萨中油田开发

Abstract:Forecasting model of reasonable injection?production ratio in each set of series of strata is built through a large number of analyses and calculations to the production data. The forecast of reasonable injection?production ratio in the whole area of Sazhong should adopt injection?production ratio and water?oil ratio method; in Sapu formation should adopt material balance method; in Gaotaizi formation should adopt multielement regression method. The change rule of injection?production ratio in the future two or three years at assuming conditions(constant production, pressure and ascending rate of water cut) can be obtained by predictive formula. The calculated results of mathematical model coincide with the matching results from injection?production ratio software basically, it presents that the mathematical model built in this study is reliable. On the basis of theoretical analyses and calculations, the influence of primary, secondary infill adjustment wells and basic well pattern on each other is given, matching relation of water injection is determined, and the measures of reasonable adjusting injection?production ratio and injection?production structure are proposed . It had good effect in production practice.
Keywords:formation pressure  water?oil ratio  injection?production ratio  mathematical model  adjustment of injection?production structure
