塔河油田缝洞型油藏含水变化预测模型研究

Research on aqueous forecast model of fractured-vuggy reservoirs in Tahe oilfield

  • 摘要: 塔河油田具有大规模缝洞发育的油藏,缝洞规模大,油藏内部油水流动已远远超出渗流范畴,油水流动分配不易出现规律性变化,因此其油井产出油水关系变化复杂,其极易受到外界因素的影响,利用聚类分析法对受多因素影响的水驱特征曲线进行分类;影响含水变化的因素很多,采用因次分析方法对多个因素提取主因子,然后利用主因子对累计产水进行回归分析,得出预测模型。预测结果表明该方法建立的预测模型能较好地对生产数据进行预测分析。

     

    Abstract: Tahe oilfield is of large-scale development of fractured-vuggy reservoirs with large scale fractures and vugs.The internal oil-water flow has far exceeded the scope of seepage,and the oil-water flow distribution is less prone to reflect regular changes,and therefore,the oil-water relationship of oil wells is complex and very easily affected by external factors.By use of cluster analysis of multiple factors that influence water drive characteristics,the curves have been classified. There are many factors affecting the water change,by using the dimensional analysis of a number of factors to extract the main factor,and then using the main factor for cumulative production water regression analysis to predict models.The prediction results show that the established prediction model with this method can better forecast and analyze the production data.
