| 以准噶尔盆地中央1区块侏罗系三工河组为例，改进成岩效应模拟研究方法，选取单井成岩指标镜质体反射 率、甾烷异构化指数、粘土矿物伊/蒙混层中蒙皂石含量、古地温和石英加大体积含量来模拟侏罗系储层的成岩演化 过程，建立单井纵向成岩演化序列。在此基础上模拟侏罗系三工河组的成岩史，得到平面i:成岩演化阶段的空间展 布特征和趋势，并对三工河组储层进行成岩相评价。研究表明,改进后的方法能够预测不同地史时期的成岩阶段和 生、储、盖层的发育;在研究区东北侧的成岩阶段为晚成岩A,期,西北侧和南侧为晚成岩八2期。 |

| Abstract: |
| The method of effect-simulation of diagenesis was improved by taking Jurassic Sangonghe formation in centric block 1 of Junggar Basin as an example. Jurassic reservoir's evolutionary process of diagenesis was simulated by diagenetic parameters including vitrinite-reflectance, sterane isomerization index，the smectite content in illite/smectite mixed layer, Paleogeotemperature and the percentage content of authigenic quartz. And the lengthways evolvement sequence of diagenesis of single well was established. The special distributing character and trend of planar diagenetic evolutive phase were acquired by simulating diagenetic history of Jurassic Sangonghe formation，and diagenetic facies was appraised. The results show that the diagenetic stages of different geologic history and distribution of source-reservoir-cap can be predicted by the improved method. The diagenetics stages in northeast of research area is A, of late diagenetic stage, and northwest and south of research area is A2 of late diagenetic stage, |
