STUDY ON INFLUENCE OF DIFFERENT PUMPING DEPTHS ON FAULT HYDROGEN OBSERVATION IN AKSU
Through five different pumping depth experiments at the depth of 5～105 cm at the Aksu fault hydrogen observation point in Xinjiang,it can be seen that there are great differences in the hy-drogen background value,daily amplitude and dynamic characteristics of different pumping depths in the fault hydrogen observation.Due to the strong penetrability and low viscosity of hydrogen diffu-sion,hydrogen has obvious uneven zonality in the vertical direction of the observation hole.And be-cause of the difference in the structural position of the observation point and the influence of meteoro-logical factors,the hydrogen background value and the quality of the observation data are different.The pumping depth of 80 cm in the hanging wall of the fault at Aksu observation point,the mean square error and coefficient of variation of fault hydrogen data are significantly better than other depths,which can be used as the preferred depth of Aksu fault hydrogen observation.
