摘要
根据矿场实际资料统计分析,基于对诸多区块进行曲线拟合,建立了产量及含水率预测模型,为油田开发规划方案的编制提供了技术保障.由矿场递减率公式和含水上升率的定义,分别确定出年自然递减率和年含水上升率的油田开发指标.通过对萨中西部过渡带水驱区块未措施老井产量、年自然递减率、年含水率及含水上升率指标的预测,表明新模型较原模型(S型)预测精度高,年含水率相对误差由0.46%可缩小到0.21%,使油田或区块的开发规划设计更具科学性.
According to the statistical analysis of actual mineral data and based on the curve fit of lots of blocks,we have establish forecast model of production and water cutting,and provided the technical data for working out the development plan of the oilfield.According to the mineral decline formula and definition of rate of water cut rise,we have determind the development index of the oilfield that are the annual natural decline rate and annual rate of water cut rise respectively.The production of the non-measure old wells,annual natural decline rate,water cut and rate of water cut rise of the western transition water-flooded block of the mid Saertu Oilfield are forecast,indicating that the accuracy of the new model is higher than the old model(S model),the relative error of annual water cut reduces from 0.46% to 0.21%,making the development plan of the oilfield or the block more scientific.
