摘要
谭增驹，张超谟等．利用粒度中值平均粒径研究陆源碎悄岩岩性与结构．测井技术，１９９５，１９（２）：１３０～１３４对利用测井信息确定粒度中值、平均粒径进行了研究。发现粒度中值、平均粒径与自然伽玛相对值、泥质含量间的较好的相关关系，利用平均粒径描述碎屑岩岩性，特别是描述浊流相、河流相砂岩岩性比粒度中值更具代表性。指出利用粒度中值，平均粒径的变化范围和规律研究陆源碎屑沉积岩的岩性粗细与结构可对单井油水层评价给出更客观的标准。
Determination of medium grain size and average grain diameter with loggingdata has been studied.It is discovered that medium grain size and average grain diameter have a rather good relation with the relative value of Gamma Ray and claycontent. Average grain diameter is even better than medium grain size in describingthe lithology of elastic rock,especially in describing sandstone litholoty of turbiditeand river factes. Therefore,a more objective criterion can be obtained for singlewell interpretation from the study of granularity and texture of terrigenous elasticsedimentary rock using the changing range and changing law of medium grain sizeand average grain diameter.
