          摘要:
          三塘湖盆地火山岩地层岩性、孔隙结构复杂,电阻率测井受背景电阻率影响大,测井定量评价难度很大。针对岩性识别、物性参数和饱和度定量计算三大难点,利用图像处理技术提取火山岩结构特征,结合常规测井资料特征,采用支持向量机方法在多维空间中识别火山岩性;以混合骨架模型和复杂孔隙结构模型为基础,评价储层基质孔隙、裂缝孔隙和渗透率等物性参数;通过消除背景导电饱和度模型,消除火山岩背景电阻?#23454;?#24433;响,并利用裂缝孔隙性地层电阻率模型确定不导电水饱和度,求取非均质的复杂孔隙结构火山岩地层含油饱和度,从而形成了一套完整的火山岩定量评价方法。
          Abstract:
          In Santanghu basin, it is difficult to quantitatively evaluate the volcanic reservoirs since lithology and porosity structure is complex and reservoir resistivity is impacted by background resistivity. For simplifying lithologic identification,physical property and saturation calculation, proposed is a set of quantitative evaluation methods: Volcanic rock structure feature is extracted from electricity images using imaging processing technology; Combining with normal logging data, lithology is identified with SVM(Support Vector Machine)method in multidimensional space; On the basis of the mixed matrix model and complicated porosity structure model, it can evaluate block porosity, fracture porosity and permeability, etc. The saturation equation of eliminating background electric conduction is used to calculate oil saturation of the heterogeneous volcanic reservoir with complicated porosity structure, and to eliminate influence of the background resistivity; and nonconduction water saturation is obtained from fracture porosity reservoir resistivity model.
