油田开发过程中,石油储采比和储采平衡率是两个极其重要的开发指标,根据经验,油田储采比的高低与油田产量变化趋势有密切关系。从预测原油产量数学模型出发,推导出了保持油田稳产最低极限储采取值公式。为使产量不致于快速递减,油田储采比应大于(1+0.746B-1)(B为常数),同时,油田储采比与产量的增长率及递减率存在定量关系。根据合理储采比制定原则,可规划出油田合理储采比,在给定合理储来比及产油量增长速度的情况下,可以确定出合理储采平衡率,从而为制定合理油田开发技术指标提供依据。表1参3(张正卿摘)
Oilfield development process, the ratio of oil storage and storage and the rate of reserves and reserves are two extremely important development indicators, based on experience, the level of oil and gas storage and production and oil production is closely related to the trend. Based on the prediction of the mathematical model of crude oil production, the formula for storing the lowest limit of steady production of oilfield is deduced. In order to prevent the output from decreasing rapidly, the ratio of oil and gas reserves should be greater than (1 + 0.746B-1) (B is a constant). Meanwhile, there is a quantitative relationship between oil and gas reserves and production growth rate and decline rate. According to the principle of reasonable ratio of storage to production, a reasonable ratio of storage to production can be planned. Given a reasonable ratio of storage to storage and the rate of oil production growth, a reasonable rate of storage and recovery can be determined, so as to formulate a rational oilfield development technology Indicators provide the basis.
