The Practice of High-Precision 3D Seismic Exploration at Tuoxie in Qianjiang Depression

According to the demand for oil and gas rolling development in Tuoxie area of Qianjiang Depression,Jianghan Geophysical Prospecting Company conducted the high-precision three-dimensional seismic data acquisition in the area in 2006.The quality of Secondary 3 D seismic acquisition in this area has been improved compared with the previous data by using not only acquisition method like wide-azimuth small bin,high coverage as well as preferred shooting lithology but also various geometry technology.The small fault block is clear in structure profile.reflected wave group is strong in continuity.All these are helpful in interpreting and describing low-amplitude structure,small fault block and lithologic reservoir.The methods of seismic data acquisition in this area can be as a reference for similar exploration areas.
