Abstract: Abstract:The important position of the shale gas in global energy resources was introduced. Considering the downstream comprehensive utilization, depending on the comparison with centralized transmission technology by pipeline and liquefied natural gas (LNG) technology, the significance of the GTL (gas to liquid) technology was pointed out, and two ways to produce specialty oil using shale gas of GTL technology were described. The classification of GTL products was summarized. The market economical efficiency of the GTL oils was analyzed, and the development direction of the GTL technology was described clear.
