Downhole PS Logging, Borehole Triaxial Geophone, Downhole 3D Geophone, Downhole Vsp Geophone, Seismic 3C Geophone
It is used to receive P- and S-waves in dry or water filled boreholes. To do downhole shear wave measurements. It can be used in slim boreholes.

It is a kind of electrodynamics velocity sensor, generally used to receive seismic waves down the hole. The geophone is made up from 3 high-sensitivity orthogonal Cartesian coordinates, which can sense the seismic wave from the 3-directions respectively. There is an air-lock wall-attached device, being to suit for drilling well of a diameter of Φ50~Φ110 (if the diameter is more than Φ110, we will supply additional chock ). Mechanic one can couple rigidly with the well utmost, so it can reflect seismic real signals better. Utilizing a special cable and gas tube, lightweight (total of 120m of cable and gas tube is 17Kg, total of 60m cable and tube is 12Kg). The outside of probe take use of metal, with steady structure for using a long time. Downhole PS Logging, Borehole Triaxial Geophone, Downhole 3D Geophone, Downhole VSP Geophone is matched with steal strings ring and lifting system. The length of geophone cable and gas tube has two kinds, 120m and 60m respectively, fit for the various log length. (The cable and tube is accustomed, that is up to you choice.) According to requirements of users, output cable is to weld into 27 cores plugs outlet and the sub box with a Q9 media cards (red, yellow and blue)
