Abstract


Seismic data acquiring is the key part during exploration. Seismic sensor is an electromechanical conversion device to transfer the seismic waves into electric signal, it’s a very important component of the field seismic data acquisition. The type of sensor can simply divided into analog and digital sensors, The analog sensors output analog singles, digital sensors output digital sensors. The wide use of sensors in exploration is still analog sensors currently, but the new direction on exploration is 3c technology, this thesis focus on the 3c digital sensor technology and use of it.3-component seismic acquisition is a cutting-edge technology in the Geophysical exploration, it’s Sensor technology, Micro-Machined electro mechanical technology, control technology combine with exploration science.This article introduces principles of several seismic sensors first, especially 3c digital sensor,. Then compare 3c digital sensor with analog sensor from theory and actual using result ,to decide the best method of using the 3c digital sensor finally .We study the principle ,structure and practical application of the 3c digital sensor, and use it in the exploration in Hailae Oilfield, we compare the analog signals and the digital signals, in purpose of gathering more effective information so as to improve accuracy ,improve data quality, increase the benefits of exploration.
