摘　　要：随着油气资源需求增加以及常规油气藏增产、稳产潜力下降,越来越多的国家开始将目光转移到非常规能源中。页岩气作为最主要的非常规能源之一,以其开发潜力大、开采寿命长、生产周期长等优点成为工程师和地球科学家们关注的焦点。页岩气藏是典型的非常规天然气藏,储层物性差、孔隙度和渗透率低,开采难度大,需要应用特殊的钻探开发技术。分析、总结了页岩气成藏机理,储层特征,以及钻探开发技术现状,特别是页岩气开发新技术——水平井技术和压裂增产技术,这两项技术的不断改进,使页岩气产量逐年提高,页岩气在全球能源供应体系中的重要作用日益显著。Rising demand and increasing pressure on energy made people pay more attention to unconventional energy resources. As an important unconventional energy, shale gas had aroused greater world attention for its advantages of huge reserves, long exploration life and production cycle and so on. Because of the bad properties of shale gas reservoir such as poor porosity and low permeability, it is difficult to exploitation so we need apply special exploration and development techniques. In this paper, on the basis of shale gas accumulation mechanism, reserves and exploitation status, introducing new progress in shale gas devel- opment technology, they are horizontal well technology and frac- turing stimulation technology, These two technologies continue to improve, so that the shale gas production has increased annually, the important role of shale gas in the global energy supply system are increasingly significant.
