【Abstract】 The article introduces the dynamic (electric potential) method to measure the fracture parameters such as azimuth,length,etc. for coal-bed fracturing. Based on many in-house physical model experiments and field tests,aiming to the inherent characteristics of coal beds,the dynamic (electric potential) method is developed. The paper introduces the basic principle,the measuring method and the measuring instruments of the dynamic (electric potential) method. Then,the application results of the method are analyzed for Well Jishi 1 in Shangxi province and Well Xi 36-10-3 in Dagang Oil Field. The results prove the feasibility of the dynamic (electric potential) method and its major role in exploration and development of coal-bed gas.更多还原
