Study on An Experimental Method of Hydraulic Fracturing of Coal - bed Gas
摘要
Abstract
According to classic curves of hydraulic fracturing test in coal seam and theoretical analysis, this paper obtained typical anal- ysis curves of hydraulic fracturing test. Taking testing well in Southern Qinshui basin as the research object, the in - situ stress of coal seam is measured. The hydraulic fracturing test data were analyzed and studied by double logarithm method and root squaring method, the empirical value of in - situ stress in Southern Qinshui basin and the mutual authentication of the two methods are accurate and cred- ible. The test results of coal - bed hydraulic fracturing provide a basis for coal - bed methane exploration, testing, discharge and min- ing operations process in late stage.关键词
