Seismic Petroleum Accumulation-forming Theory In Reservoir Description

With the development of seismic exploration technology,three-dimensional earthquake and even four-dimensional earthquake in the growing popularity.The application of seismic data in reservoir description has become more and more.The occurrence of seismic sedimentology in the 1990 s caused the rapid development of seismic reservoir formation.The seismic segregation is a new discipline formed by the combination of advanced seismic exploration technology and modern oil and gas accumulation theory,that is,the principle and method of modern oil and gas accumulation theory,and the rationale for the treatment and interpretation of seismic exploration technology,Scientific geological interpretation,so as to obtain oil and gas generation,migration,aggregation,preservation and distribution of the theoretical summary.The theory of seismic exploration and the theory of modern oil and gas accumulation theory constitute the core content of seismic reservoirs.The biggest difference between seismic reservoir theory and other oil and gas reservoir theory is that it can make full use of the high-precision seismic wave field spatial information brought by seismic information,and use the most advanced oil and gas accumulation theory to guide the two The unity.Through the advanced seismic exploration technology,the formation and distribution of oil and gas reservoirs contained in the seismic exploration data can be fully revealed,and the oil and gas reservoir formation theory can be explained by reasonable explanation and scientific analysis.,To determine the nature of oil and gas distribution.Based on the theory and method of seismic accumulation theory,this paper mainly discusses the reservoir description of the Triassic Bayanquan reservoir in the study area,based on the research project of "Mantang slope Permian-Triassic target evaluation and high quality reservoir prediction" problem.According to the characteristics of the relevant data,the main geological factors such as raw,storage and circulation in the study are studied.The relationship between the TOC content and the source rock and the reservoir rock is discussed by focusing on the seismic recognition method and prediction effect of the total organic carbon(TOC).Based on the seismic information combined with the known drilling and drilling information,The relationship between reservoir rocks,reservoirs and traps is described,and the spatial distribution of favorable reservoirs in the study area is pointed out,which provides a scientific basis for the exploration and development of the study area.
