The Application of 3-D High Resolution Seismic Exploration Technology in Well 2 of Mobei in Zhungaer Basin

By using the technology of medium frequency geophone, small CMP bin,high coverage,optimizing shot-receive line pattern,big refraction-dune curve method,dynamic static correction iteration and high resolution velocity analyses,high SNR(Signal-to-Noise Ratio) and high resolution 3-D seismic data has been gathered the first time at the massive desert of Zhungaer Basin. The travel time and frequency range found at the interest zone Jurassic system is 2.0~3.0s and 10~90Hz,main frequency is 50Hz. Through interpretation of the seismic data, another new 17 minor faults has been found(fault throw 10~20m).
