川西坳陷中部须二段储层流体包裹体特征及在油气充注史研究中的应用

摘要

The fluid inclusions in the hydrocarbon reservoirs from the second member of the Xujiahe Formation in western Sichuan depression may be divided into two categories: saline inclusions and hydrocarbon inclusions, which represent three stages of hydrocarbon infilling, i. e., low maturation to maturation stage, maturation to high maturation stage, and high maturation to supermaturation stage.%川西坳陷中部须家河组二段(T3x2)储层中的流体包裹主要为盐水包裹体和烃类包裹体.可划分为三种类型,分别代表了油气充注的三个阶段:低成熟-成熟生油气充注阶段、成熟-高熟生油气充注阶段和高成熟-过成熟生气充注阶段.
