Product Description

Downhole Seismic Testing Geophone 3 Channels VSP Seismic Survey Seismograph Geophone Triaxial Borehole Seismic Survey Equipment



Downhole seismic testing geophone is a specialized instrument used in borehole seismic surveys to measure and record ground vibrations caused by seismic waves. It is designed to be deployed in a well or borehole and is specifically configured to capture seismic signals with high sensitivity and accuracy. The geophone serves as a key component in downhole seismic data acquisition, enabling the characterization of subsurface formations and analysis of seismic wave behavior.



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)

1. Triaxial configuration: The downhole seismic testing geophone is typically designed with three orthogonal sensing axes (X, Y, and Z) to capture ground motion in multiple directions, allowing for comprehensive seismic data acquisition.

2. High sensitivity: These geophones are built with high-quality sensors that can detect even low-amplitude seismic waves, ensuring reliable and precise measurements of ground vibrations.

3. Compact and rugged design: The geophone is engineered to withstand the harsh downhole environment, with robust construction that can withstand high pressures, temperature variations, and other challenging conditions encountered in wellbore operations.
