《穷举法计算水淹层饱和度及地层水混合液电阻率》
建立了简单的水淹层体积模型,得到了一个关于混合液饱和度Swz和混合液电阻率Rwz的方程。它可以与印度尼西亚公式一起建立联立方程组。本文提出了用迭代法来求解此方程组,以求出Swz和Rwz。此方法在渤海湾X油田取得成功。
《Calculation Of Remaining Oil Saturation And Mixed Fluid Resistivity By Exhaust Algorithm》
Description
A simple volumetric model of water flooded zone was established to develop an equation for calculating saturation(Swz) and resistivity(Rwz) of mixed fluid. It can be combined with Indonesia Formula to get a set of simutaneous equations. The paper presents a new method to obtain Swz and Rwz by Exhaust Algorithm. The implementation shows that the method is effective and practicable in X oilfield in BoHai Bay
Applications
In similar conditions, it can be used as a source of reference to obtain Swz and Rwz, which are necessary to excavate remaining oil.
Results, Observations, and Conclusions
It is a better way to research the model of water flooded zone for evaluation of remaining oil saturation and mixed fluid resistivity. When there is only one type of injected water, Swz and Rwz can be obtained by Exhaust Algorithm.
Significance of Subject Matter
The paper gives a new method to obtain Rwz and Swz.
