Abstract: The splitting pressure is an important parameter in the oil extraction. Based on the analysis of influence factors of splitting pressure, seven fracturing methods used in the world are briefly reviewed. These methods are: hydraulic fracturing, geothermal fracturing, high energy gas fracturing, foam fracturing, supercritical carbon dioxide fracturing, acid fracturing and liquid nitrogen fracturing. Key factors that causing the splitting in each method and their advantages as well as disadvantages are also presented. Based the geological conditions in the Tahe oilfield, four applicable fracturing methods are selected.
