| The Application of “HRS” Seismic Exploration Technology to Making Breakthrough of the Seismic Imaging “Bottleneck” of the Marine Mesozoic–Paleozoic Strata in the South Yellow Sea Basin |
| Due to the extensive existence of high-velocity shielding layer, the seismic reflection of marine Mesozoic–Paleozoic has poor even no reflection, which hinders the progress of deep hydrocarbon exploration. On the basis of the last ten years’ research characterized by in-depth theoretical calculation and simulation, long-term sea trials and several rounds of processing tackling, researchers have founded the “HRS” seismic exploration technology and thus broken through the seismic imaging “bottleneck” of the marine Mesozoic-Paleozoic strata in the South Yellow Sea basin. The “HRS” seismic exploration technology is made of two parts. The seismic acquisition part has the characteristics of high coverage, low-frequency and strong energy source. The key goal of the processing system obtains the effective reflection with high signal-to-noise ratio, rich low frequency and strong amplitude. The seismic data of high quality was acquired with “HRS” technology and internal structure of marine Paleozoic strata was revealed clearly. Finally several large trap structures were found and the drilling targets were determined. The “HRS” seismic exploration technology provides effective technical support for the strategic discovery and breakthrough of oil and gas exploration in the deep part of sea area. |
