调驱措施效果预测方法的研究及应用

通过系统地分析区块、单井组调驱后的效果资料，归纳出影响调驱效果的主要因素，结合概率论建立经验统计的效果预测方法．分别预测区块及单井调驱所达到的增油量、降水量、增加的可采储量等指标，从而为调驱措施的有效实施提供可靠的依据。通过在濮城油田东区沙二上1油藏上4口井与濮城浦田西区沙二上2＋3油藏濮4南区的应用．证实该方法应用简便，预测精度高，具有一定的实用性。

A Method to Predict Effects of Profile Control and Oil Displacement and Its Application

The main factors to influence profile control and oil displacement are summarized by systematically analyzing block and individual well data,and an empirical and statistical method is established for predicting effects of profile control and oil displacement by combining with the probability theory.This method has been applied to predict increased oil production,reduced water production and enhanced recoverable reserves by profile control for blocks and individual wells respectively,providing a reliable basis for effectively implementing profile control.The application in 4 wells of SHA2-U1 reservoir and in PU4 south area of SHA2- U2＋3 reservoir,Pueheng oilfield,has demonstrated that the method in simple and easy to use,high in prediction accuracy and quite practical.
