为了深入研究火山岩储层导电机理,建立合理的火山岩储层导电及饱和度解释模型。在参阅国内外相关文献的基础上,深入分析研究包括经典Archie模型、考虑泥质影响的导电模型、考虑骨架及孔隙结构影响的导电模型和非均质条件下基于网络导电模型等诸多导电模型,除基本的Archie模型以外,其他各类中均含有多种储层导电解释模型。通过对已有导电模型的分析,建议火山岩储层导电机理研究从储层特征(岩性、导电矿物、流体性质、孔隙结构)分析入手,在岩石物理实验及理论研究的基础上开展电阻率影响因素分析,进行导电机理理论研究,建立不同孔隙结构类型的火山岩储层导电模型,在此基础上,建立饱和度解释模型及流体识别方法,最终形成一套适用于火山岩储层的导电机理理论和饱和度解释方法,在此基础上初步建立了中基性火山岩储层导电模型。
In order to further study the conductive mechanism of volcanic reservoirs, a reasonable interpretation model of conductivity and saturation of volcanic reservoir is established. On the basis of referring to relevant literature at home and abroad, this paper deeply analyzes and studies the conductive model including classical Archie model, muddy effect, conductive model considering the influence of skeleton and pore structure and many conductive models based on network conductive model in heterogeneous condition, In addition to the basic Archie model, a variety of other types of reservoir contain conductive interpretation model. Based on the analysis of the existing conductive models, it is suggested that the study on the conductive mechanism of volcanic reservoirs should start with the analysis of reservoir characteristics (lithology, conductive minerals, fluid properties and pore structure) and on the basis of rock physics experiments and theoretical studies Factor analysis, conductive mechanism theory research, the establishment of volcanic reservoir conductivity model of different pore structure type, on this basis, the establishment of saturation interpretation model and fluid identification methods, and ultimately the formation of a set of suitable for volcanic reservoir conduction mechanism theory and Saturation interpretation method, on the basis of which initially established the conductivity model of volcanic rocks in the middle-base.
