摘要
页岩气是指那些聚集在暗色泥页岩或高碳泥页岩中,以吸附或游离状态为主要存在方式的天然气。页岩气属于非常规气藏,储层具有低孔、低渗特征,与常规的气藏相比,页岩气具有特殊的地质特征,因此,其高效的开发也必须使用特殊的开发技术,我国页岩气开发潜力巨大,但页岩气研究相对滞后,目前,我国页岩气的开发刚刚起步,本文介绍了页岩气资源的分布状况、页岩气成藏机理,吸附与解吸机理,从页岩气勘探技术、开发技术两个方面介绍了页岩气发展的现状,并指出了页岩气的发展方向。
Shale gas is natural gas which gathered in dark mud shale or high carbon mud shale with adsorption and free state. Shale gas belongs to unconventional gas reservoir; the reservoir has low porosity and low permeability; compared to the conventional gas reservoir, shale gas geological characteristics are special, so its efficient development has to use special development technology. Our country shale gas has great potential for exploitation, but shale gas research lags relatively. At present, our country shale gas development has just started. In this paper, the distribution of shale gas resources was introduced as well as shale gas accumulation mechanism, adsorption and desorption mechanism. Present situation of the shale gas was discussed from two aspects of exploration technology and development technology, and development direction of the shale gas was pointed out.
