摘要
Abstract
Due to strong heterogeneity and big differences of properties in coal reservoir, the fracturing curves show various shapes. Based on analysis of the fracturing operation curve of over 200 wells in seam 3 in southern Qinshui basin, it is summed up that the prepad fluid stage was divided into descending type, descending-undulating type, stable type and descending-stable types, and the sand-carrying fluid stage into descending type, descend-ing-stable type, ascending type, stable type and undulating type, the pressure drop measurement stage into sharp pressure drop type and slow drop type. At the same time, the reasons for each type were explained. Finally, related suggestions were given for fracturing operation.关键词
