摘　　要：火山碎屑沉积岩储层普遍含有凝灰质,而凝灰质的测井响应十分复杂,为储层的测井评价带来了很大难度.本文介绍了多种国内外的含有凝灰质的火山碎屑沉积岩的测井评价方法,尤其是凝灰质含量的计算方法.我国学者提出的最优化测井解释方法、相对指示法和统计法等可以解决火山碎屑沉积岩储层模型中的成分含量问题;阿根廷的Alberto Khatchikian和Pedro Lesta等人利用声波、密度和中子曲线求取泥质和凝灰质含量的解释方法,通过标准化砂-泥岩的方法得出含水饱和度和孔隙度,并且已投入使用;TOSHINOBU ITOH利用阳离子交换量(CEC)对火山凝灰岩进行测井解释.这些方法对进一步评价火山碎屑沉积岩储层奠定了基础.It is generally known that tuffaceous＇ logging response is extremly complex, but volcaniclastic sedimentary rock reservoirs generally contain tuffaceous, which lead to the difficulty of logging evaluation. This paper introduced several logging evaluation methods for volcaniclastic sedimentary rocks, especially the calculation methods of tuffaceous content. Optimization method of log interpretation, relative indication method and statistical method which Chinese scholars presented can solve the component content of volcaniclastic rock reservoirs model. Alberto Khatchikian and Pedro Lesta et al used acoustic, density and neutron curves to calculate shale content and tuffaceous content, and calculate saturation and porosity by means of standard sand-mudstone model. TOSHINOBU ITOH used cation exchange capacity （CEC） to interpret volcanic tuff. Besides, the paper provided a complete set of method for volcaniclastic sedimentary rock evelulation. The methods mentioned above lays a foundation for further evaluation of volcaniclastic sedimentary rock reservoirs.
