Several ideas on deep water oil and gas comprehensive geophysical data acquisition from marine experiments

With the development of global marine oil and gas exploration, deep water geophysical data acquisition technology has been constantly improved. Drawn upon our marine experiments, this article puts forward several ideas on deep water oil and gas geophysical data acquisition. It focuses on how to choose seismic parameters, the real time monitoring of gravity, magnetic, seismic data acquisition, and also concludes the two progresses we have made in deep water oil and gas geophysical data acquisition after the sea testing: one is 2D seismic data acquisition technology by high precision positioning long-streamer; the other is comprehensive geophysical measurement technology monitored by high accuracy gravity, magnetic and seismic joint data acquisition, which provide technical guarantee for deep water oil and gas exploration.
