在对已调剖井增油降水效果评价的基础上,建立起调剖井的井口压力指数、注水压力、注水量、对应油井平均含水率、堵剂用量和效果的样本库,利用人工神经网络方法建立起调剖效果与这些影响因素的定量关系,以此为调剖效果的预测模型。该模型可预测不同地质特征和工艺条件下的调剖效果。矿场应用结果表明,该方法预测结果可靠性较高。

This paper gives the evaluation model about the oil incremental and water decreasing results of profile control wells.It analyzes the factors that will influence the result of profile control and establishes the representative species base including those factors and the corresponding results of profile control.The prediction model of profile control is established based on the representative species base by using artificial neutral network.That model can predict the result of the profile control wells having different geological characteristics and process conditions.The applied result shows that the result prediction model of artificial neutral network for profile control is accurate,reliable and effective.
