摘要
针对实验设备和测试手段受限制、实验方法周期长、价格昂贵和误差较大的特点,提出了采用油藏生产历史数据进行线性回归来确定模型参数的新方法,建立了裂缝性油藏产量预测及最大渗吸速度发生时间的数学模型。通过实例分析和对比,验证了该方法的可靠性。对裂缝型油藏水驱开采动态研究具有参考价值。
Restricted by experimental equipment, methodologies, long period of experiment, high cost and greater errors, a new linear regression method by using reservoir historical production data is derived to determine the model parameters. The models of productivity prediction and the time of maximum imbibition's rate are then presented. A real reservoir case is calculated and compared using the method. The results show good agreement with reservoir productivity data, which is of reference to the dynamic study on water flooding production of fractured reservoirs.
