页岩气作为一种新生代气藏,与常规天然气藏相比具有很大的差别。然而我国的页岩气勘探开发还处在初级阶段,寻求新的理论和方法进行页岩气的大规模开采迫在眉睫。本文主要通过页岩气/常规天然气成藏的主控因素、成藏特点、分布特征、气藏规模、赋存机理及勘探开发特点几个方面进行对比分析研究,从而更加全面科学地了解页岩气藏。
As a Cenozoic gas reservoir, shale gas is very different from conventional gas reservoirs. However, the exploration and development of shale gas in China is still in its infancy, and it is imperative to seek new theories and methods for large-scale shale gas exploitation. In this paper, comparative analysis of the main controlling factors of shale gas / conventional gas accumulation, reservoir forming characteristics, distribution characteristics, gas reservoir size, occurrence mechanism and exploration and development characteristics are carried out to understand shale more comprehensively and scientifically Gas reservoir.
