摘要
利用岩石组构法(RFN)、孔隙几何形状法(R35)、流动带指标法(FZI)、水体积法(BVW)和修正的地层洛伦兹图版法(SMLP)对厚层碳酸盐岩油藏MF的流动单元进行定量划分。结果表明:RFN法识别的Ⅰ类流动单元可信度较高; R35法对Ⅰ、Ⅱ、Ⅳ类流动单元的聚类效果明显; FZI法对Ⅲ、Ⅳ类流动单元的分类效果较好; SMLP法适合划分不同类型流动单元边界,同时也可以识别出高速流动区和隔挡层。综合使用上述几种方法,可以有效避免方法自身缺陷和数据异常造成的流动单元划分不准确。
The flow units of MF thick carbonate reservoir are quantitatively divided by rock fabric method( RFN),pore geometry method( R35),flow zone index method( FZI),water volume method( BVW) and modified Lorentz map method( SMLP). The results show that to identify type I flow units by using RFN method is of high reliability;R35 method is of obvious clustering effect to type I,Ⅱ and IVflow units;FZI method is of better classification effect to type Ⅲ and IV flow units;SMLP method is suitable for dividing the boundary of different types of flow units,and can also identify high-speed flow areas and barriers. Combining these methods can effectively avoid the inaccurate division of flow units caused by the method’s own defects and data anomalies.
