China Petrochemical News Network recently, the Shanghai Bureau of Geophysical Prospecting Branch and Qingdao Institute of Marine Geology jointly declared the "South Yellow Sea Marine Meso-Palaeozoic" high coverage frequency, rich low-frequency signal, strong seismic source energy "seismic detection technology" project obtained 2020 Second Prize of Ocean Engineering Science and Technology
.
This award is the country's first highest scientific and technological award in the field of marine engineering established by the China Ocean Engineering Consulting Association after registration and approval by the Ministry of Science and Technology.
The South Yellow Sea Basin is a basin in which a continental Meso-Cenozoic basin and a marine Meso-Palaeozoic basin are superimposed.
It is also the only large-scale sedimentary basin where no oil and gas fields have been found in the offshore China
.
Aiming at the problems of old marine Meso-Palaeozoic strata age, deep burial, complex structure, and poor imaging quality of seismic data, Wufen and Qingdao Institute of Marine Geology conducted data acquisitions in 2010, 2015, and 2016, and passed a large number of The acquisition design, simulation, testing, production and other technical researches have formed a "high rich and strong" seismic detection technology characterized by high coverage times, rich low-frequency signals, and strong seismic source energy, breaking through the seismic imaging under the condition of shallow strong reflection interface energy shielding The technical bottleneck provides a good data basis for the next resource evaluation
