摘要

针对油田高含水期中水驱、聚合物驱共存,且实施提液增产措施后,单井产量的预测值与实际产量误差较大这一问题,研究了水驱及聚合物驱产量预测的方法。通过对目前在用的"水驱、聚合物驱提液措施"产量预测方法的研究,找出了导致"水驱、聚合物驱提液措施"产量预测误差较大的原因,借助于油气藏渗流理论,并结合油田实际情况,在理论上寻求能够对"水驱、聚合物驱"通用且方便快捷、精度适中的通用预测方法,即广义IPR产量预测方法。现场应用该方法,对13口提液井进行了产量预测,平均误差为7%,原预测方法的平均误差为21.54%,提高了预测精度,达到了预期的目的。广义IPR产量预测方法为进一步提升油田开发的管理水平提供了有力的技术支持。
During the high water cut period, both water flooding and polymer flooding methods are all adopted. The production prediction of single well and actual production has large error after stimulation to increase liquid.Therefore, the production prediction method for water and polymer flooding wells has been researched, and the reasons that result in the production prediction error were found out. By means of the seepage theory of hydrocarbon reservoirs and combined with actual conditions in oilfield, the common and convenient prediction method with proper precision has been obtained theoretically, which is called generalized IPR production prediction method,which has been applied in 13 stimulated wells to predict the production. The average prediction error is only 7%,while the former prediction method has the error of 21. 54%,which has improved the prediction accuracy and achieved the desired purpose. The generalized IPR production prediction method can provide a strong technical support for further enhancing the management level of oilfield development.
