中国大陆区煤层气盆地分类方案

从煤层气富集成藏地质条件分析入手,在研究聚煤盆地的时空演化、后期改造特征基础上,将煤层气盆地定义确定为"具有工业价值煤层气藏形成和保存条件含煤盆地",并认为煤层气盆地内煤层气富集成藏受盆地聚煤期及后期改造的动力学机制与构造特征的控制。在系统研究盆地、盆地改造及聚煤盆地分类原则与方案基础上,提出"聚煤盆地原型类型+改造作用类型(构造样式)"的煤层气盆地双层次分类与命名方案,并对聚煤盆地原型类型和改造类型及样式进行了探讨。

The Classification Scheme of Coalbed Methane Basin in Mainland China

To start with the analysis of geological feature of coalbed methane accumulation,on the basis of the characteristic of researching in coal accumulating basin space-time evolution、post transformation,the meaning of coalbed methane basin is definited as "coal province basin which is of industry value coalbed methane accumulation formation and preservation condition",and it was considered that coalbed methane accumulation ruled by dynamic mechanism and structural features in coalbed methane basin during the course of coal-forming period and post transformation.On the basis of systematic study of basin、basin transformation and classification principle and scheme of coal accumulating basin,advise about "coal accumulating basin prototype type+ transforming function(structural styles)" coalbed methane basin dual-level classification and naming scheme,and discussed coal accumulating basin prototype type and transforming types and styles.
