摘要
在考虑边界层效应及启动压力梯度的两相渗流数学模型基础上,以注水井吸水剖面为边界条件,考虑油井见水前、后两种情况,建立了以生产井累计产油量、瞬时产液量、含水率为目标函数的吸水剖面综合解释模型。以L11–41井组为例,对不同时间测试的吸水剖面进行了井间渗透率、饱和度以及平均饱和度解释,同时以该井组内L11–131井解释饱和度与现场PND和RT饱和度测井结果进行对比。结果表明:吸水剖面综合解释结果与测井解释结果吻合。利用吸水剖面资料进行储层参数综合解释,在一定程度上可以定量描述注采井间主渗通道参数大小,为油田注采关系调整及井间挖潜提供指导。
Based on the two-phase fluid flow mathematical model and considering the border stratum and thresholdpressure gradient,using injection profile,cumulative oil production,production fluid rate and water cut of productionwell as object function,the interwell reservoir parameters interpretation method using injection profile isestablished. Using this method in L11-41 group wells,we compare the interpretation results with the results of PNDand RT log method. Results show that the parameters agree with the results of log. The interpretation method ofinjection profile can be used to interpret reservoir parameters and can provide an instruction for oil field developmentand adjustment in order to enhance oil recovery.
