Technical advance and developmentof China geophysical equipment

Wang Tiejun,Hao Huimin,Li Guoqi,Luo Fulong,Tao Zhifei,Chen Lianqing,Hou Jinhai

Strategic Study of CAE 2010, Volume 12, Issue 5,   Pages 78-83

Abstract:

The rapid growth of China petroleum industry has brought about the steady development of its geophysical equipment technology. For example, our seismic instrument has experienced its sixth upgrade. As a result, our geophysical equipment technology has met world advanced standards. After 20 years of painstaking efforts in R&D and by means of technology-introducing, digesting, absorbing, and innovating, some of our vibrator technologies have reached the world advanced level and still some have taken the world leading positions. Our seismic auxiliary equipment has much improved and earned its reputation in the global market after 30 years of independent R&D.
