The Drilling Techniques and Incident Handling for the Project of Seismic Observation Well in Jingzhou
Abstract:The borehole seismograph can monitor many weak seismic wave that the ground seismographic station cannot record， it can also reduce the ground noise interference and greatly improve the accuracy of the seismic source location. For the entire region of Jianghan Plain， the formation condition of which is thick cobble layer and viscous and easy hole shrinkage soil layer. This paper introduces the key technology of well drilling the project of earthquake monitoring well in Jingzhou， and the accident treatment of the breaking of rod in the process of drilling.
