Primary Research On Reservoir Accumulation Seismology

Reservoir Accumulation Seismology(SAS)is an new discipline of combining Seismic exploration techniques with achievements of modern hydrocarbon accumulation theory,namely the theoretical summary of using modern hydrocarbon accumulation theory and principles,methods of processing and interpretation of seismic exploration technology and achievements by reasonable scientific geological interpretation to obtain hydrocarbon generation,migration,accumulation,preservation and distribution.Seismic information,processing and interpretation results of high-precision seismic exploration techniques and principles of the Oil and Gas Reservoir comprise the core of modern Reservoir Accumulation Seismology.The difference between Reservoir accumulation seismology and other Reservoir Science is that SAS can use seismic information more directly,faster,more efficiently that seismic exploration techniques reveal about the formation and distribution of oil and gas reservoirs,and with the most advanced hydrocarbon accumulation theory as guide,SAS can reflect the overall guidance of the advanced theory and emphasize the relevance and practical value of the advanced technology,which is helpful for understand the geology and to further reveal the complexity of subtle traps,accumulation process and the distribution of the essential characteristics of scientific exploration.Through advanced seismic technology,oil and gas seismic data can be included in the reservoir formation and distribution of reservoirs for a reasonable interpretation and analysis showing how to determine the nature of the distribution of oil and gas reservoirs.This paper discusses the geological study of SAS focusing on the static elements of reservoir accumulation factor,mainly to study seismic prediction and interpretation techniques of the source rock,reservoir,and caprock,so as to explore the basic contents of SAS,which covers the use of seismic information for the horizons interpretation,spatial distribution of the fine structure and the prediction of the thickness and distribution of the source rock,reservoir,and caprock.The case studies both for caprock formation and source rock formation characterization from onshore and offshore data have been provided to prove SAS practicable and the advances.The case study on caprock formation characterization gives the results of the caprock distribution and the relationship between caprock and reservoir.The case study on source rock formation characterization gives the results of source rock distribution by TOC contents.
