6、成岩阶段划分基础上，增加了酸性水介质(含煤地层)环境下碎屑岩成岩阶段划分的标准和依据，以及碱性水介质(盐湖盆地)环境下成岩阶段划分的标准和依据;—在成岩阶段划分指标上增加了泥岩最大热解峰温T-指标;—增加了用伊利石结晶度划分成岩阶段的标志。本标准从生效之日起，同时代替SY/I'5477-920本标准的附录A和附录B为规范性附录。本标准由石油地质勘探专业标准化委员会提出并技术归口。本标准起草单位:中国石油勘探开发研究院实验中心、中国石化江汉油田分公司勘探开发研究本标准起草人:应凤祥、何东博、龙玉梅、林西生。SY/r5477-

7、2003碎屑岩成岩阶段划分1范围本标准规定了碎屑岩成岩阶段的命名及划分的依据、标志和方法。本标准适用于石油天然气行业碎屑岩成岩阶段划分及特征研究。2规范性引用文件下列文件中的条款通过本标准的引用而成为本标准的条款。凡是注明日期的引用文件，其随后所有的修改单(不包括勘误的内容)或修订版均不适用于本标准，然而，鼓励根据本标准达成协议的各方研究是否可使用这些文件的最新版本。凡是不注日期的引用文件，其最新版本适用于本标准。SY/T5163-1995沉积岩粘土矿物相对含量X射线衍射分析方法3术语和定义下列术语和定义适用于本标准。3.

8、1成岩阶段diageneticstage碎屑岩成岩阶段指碎屑沉积物沉积后经各种成岩作用改造直至变质作用之前所经历的不同地质历史演化阶段。可划分为同生成岩阶段(syndiageneticstage)、早成岩阶段(earlydiageneticstage)、中成岩阶段(middlediageneticsta
