Research On Seismic Attributes And Its Application In LF13Low-lying Land Area

Seismic data provides a wealth of geophysical information, development of seismic attribute technology can effectively reservoir prediction and layer inversion.It plays an important role in the actual production. This article rely on’LF13Depression Seismic Attribute Analysis and Application’, by LF13depression three-dimensional zone fine interpretation of seismic data based on seismic wave mechanics and kinematics characteristics to seismic attribute analysis. By using obtained seismic attribute information for optimization analysis, undertakes a number of properties based on reservoir prediction in the region results, comprehensive properties analysis for prediction of favorable reservoir zone. Analysis characteristics of depositional systems and sand body distribution, utilization of geological-geophysical method on the comprehensive evaluation for reservoirs of the Paleogene.Papers to Earth physics theory for guide, utilization of integrated using depositional theory, layer sequence formation theory, earthquake deposition theory, geochemical and layer lithology entrapment of recognition and the integrated evaluation, based on these theory principle and technology method, through seismic of integrated research, on ancient Hanjiang delta analysis, establish LF depression Paleogene high precision layer sequence formation frame, recovery research area Paleogene layer face ancient geographic, stated constructed evolution features and the prototype basin nature. Analysis of sedimentary facies types of the ancient Hanjiang delta system, revealing the ancient Hanjiang delta depositional system of developmental evolution, on the basis of analysis to favorable exploration zones and priority areas of formation conditions of lithologic trap development and regulation. In explanation of high-precision sequence framework down, fine structure interpretation of three-dimensional seismic data, seismic attribute analysis, combined with geological tectonic background for reservoir prediction. Through the Paleogene sedimentary characteristics and reservoir combinations and summarizing of knowledge, to further increase the economic effect of the oil reserves in the area.The research results achieved:clearly outline the range of different periods of ancient Hanjiang delta, growth characteristics and favorable belt. Reveal the ancient Hanjiang Delta oil and gas reservoir formation conditions and favorable zones, on the basis of predecessors research results, improve the high resolution sequence stratigraphic framework. By important sequence interface for constructing the ancient landscape recovery, analysis of sediment source,summarizes the distribution characteristics and system of different sequence in ancient Hanjiang Delta evolution.
