Research and practice on amplitude preservation processing of Neogene seismic data in Bohai Oilfield
With the continuous improvement of the degree of seismic exploration,the discovery of large and medium-sized oil and gas fields has become more and more difficult.Subtle lithological oil and gas reservoirs have gradually become important exploration targets.The accurate representation of complex lithological reservoirs requires higher-quality seismic data.Amplitude is the key to improve the success rate of lithological exploration.In view of the difficulties in lithological exploration and the demand for data amplitude preservation,the main problems faced by the seismic data preservation processing of the Bohai Oilfield are first analyzed.Based on the conventional amplitude preservation processing ideas and application effectiveness analysis,the seismic response mechanism is studied in detail.We have conducted relevant research on the optimization of processing processes and parameters based on the actual geological characteristics of different regions;In response to the problem of special geological bodies causing seismic data to not reflect actual geological characteristics,the amplitude preservation of seismic data is improved through the fusion processing of seismic data collected from different batches.The study has provided an important data basis and reference basis for the two hundred million-ton lithologic oil fields discovered in the Bohai Oilfield.
