| 摘 要： | 扬子陆块中、新生代宏观构造演化和变形的差异制约着中、古生界海相地层差异成烃演化和成藏流体源类型。为揭示这一关系，通过对该区自印支期以来构造演化的分析和差异构造变形的解析，以晚燕山-早喜马拉雅期为关键构造变革期，将其分为4类构造形变区，并相应建立了中、新生代海相烃源岩成烃演化过程。据研究结果认为：①上扬子四川盆地持续埋藏-晚期隆升的构造变形使得成烃演化具有完整的有机质“接力成气”模式，成藏流体源为干酪根裂解气、原油裂解气和沥青裂解气；②上扬子北缘和西缘差异隆升-推覆埋藏构造形变区海相烃源岩成烃演化在推覆体上、下盘发生分异，下盘成藏流体源为干酪根裂解气和原油裂解气，上盘为残留烃源；③中扬子强烈隆升-海相暴露形变区海相烃源岩自印支期末进入热裂解阶段，早燕山期末以来，烃源岩生烃停止，成藏流体源为残留气态烃源；④下扬子和中扬子强烈暴露-断陷埋藏形变区关键的成烃演化为晚燕山期以来的二次生烃，成藏流体源为二次生烃和残留烃源。

| Abstract: | Differential hydrocarbon generation and evolution as well as their genetic types in the Mesozoic and Paleozoic marine sequences are controlled by the differences of Meso-Cenozoic macroscopic tectonic evolution and deformation in the Yangtze Massif.Based on the analysis of tectonic evolution and differential tectonic deformation since the Indosinian epoch,the study area is divided into 4 tectonic deformation zones with the Late Yanshan-Early Himalayan epoch taken as the major tectonic deformation stage,and t... |
