Abstract
With the world economy and the continuous improvement of science and technology, the demand for oil is facing increasingly serious situation grow with each passing day, the energy in the world and petroleum exploration are facing more and more challenges. With the gradual shrinking of seismic exploration market onshore, offshore exploration has become the main market of seismic exploration. In recent years, the discovery of oil and more than half of the natural gas from Yu Haiyang, especially in the deep sea. The deep-water oil and gas exploration has become the global exploration of oil and gas resources in the most important areas. Many cable seismic exploration has great exploration depth, the exploration of high efficiency and many advantages of higher signal-to-noise ratio data, especially in deepwater seismic exploration plays the most important role the marine environment is complex and changeable. The cable seismic data noise characteristics, starting from the multi cable seismic acquisition mode, in-depth study of the noise characteristics and noise suppression in the future Deepwater oil and gas exploration has a very farreaching significance. In the offshore seismic exploration, how to accurately identify and effectively suppress multiple wave is a difficult problem facing long-term field of seismic exploration. The sea cable data multiples of serious, effective wave energy greatly reduces the interference, the resolution of data collection, analysis speed to follow-up, migration and geological interpretation has brought great difficulties. Based on the multiple wave of sea cable in seismic data, respectively, using anisotropic Radon transform and SRME technology to suppress multiple waves, the anisotropy of the Radon transform on the big shift from deep water multiple removal effect, SRME method of near offset multiples energy suppression effect is good. The advantages in the final synthesis of the two approaches proposed in this paper, using Radon transform and anisotropic SRME combined with the suppression of multiple waves of the ocean, the treatment effect is significant, greatly improved the signal to noise ratio of the data acquisition
