高含水期粉砂岩储层水淹层解释方法研究

Water-out Reservoir Interpretation Method in Siltstone Reservoirs at High Watercut Stage

针对高含水期粉砂岩储层水淹层测井解释存在的问题,通过密闭取心分析资料与测井资料的结合,建立了有关参数解释模型,研究了用产水率来解释水淹层的方法,提出了相渗实验束缚水饱和度的标定方法,探讨了残余油饱和度的大小对高含水期水淹层解释的影响。

In consideration of the problems of water-out reservoir logging interpretation in siltstone at high watercut stage, an interpreting model of related parameters is established, a method for interpreting water-out reservoirs by using water production rate is studied in combination of sealing core analysis data with logging data. A method for demarcating irreducible water saturation is proposed for relative permeability experiments and the effect of the size of residual oil saturation on water-out reservoir interpretation at high watercut stage.
