利用水平井钻探和水力压裂相结合的方法开采页岩气是目前的一个发展趋势。页岩气属于典型的非传统型油气资源,潜力巨大,在未来几十年里,其开发利用将会对能源安全产生积极影响。不仅如此,页岩气取代煤炭用于发电,将会使页岩气开发成本更低,效益更高,也减少了二氧化碳的排放量,减少对气候变化的影响。页岩气开采过程中水力压裂易污染地下水,但这 The exploitation of shale gas by the combination of horizontal well drilling and hydraulic fracturing is a trend at present. Shale gas is a typical non-traditional oil and gas resource with great potential. Its development and utilization will have a positive impact on energy security in the coming decades. Moreover, shale gas displacing coal for power generation will make shale gas development cheaper and more cost-effective. It will also reduce carbon dioxide emissions and reduce the impact on climate change. Hydraulic fracturing in shale gas exploration is likely to contaminate groundwater, but this
