The Research Of Seismic Reservoir Prediction In Xin Hypomere Of Jinjiachang Area

Jinjiachang field 3-D seismic area is located in the south of Jiangling Sag, across Zifushi syncline belt, slope zone of Gongan, the district into oil and gas geological condition is good, with the formation of Qianjiang Formation, Jingsha, Xingouzui group of multilayer and igneous rocks, sandstone reservoir set favorable conditions for reservoir type is Jiangling Sag under further oil and gas exploration breakthrough of important area.Seismic reservoir prediction technology is a kind of reservoir geological comprehensive evaluation technology that serving to oil and gas field exploration and development, especially in geologically complex areas, studying on reservoir prediction can accurately and comprehensively predict the favorable reservoir distribution zone,trap well, effectively guide the oil and gas exploration.This article first summarizes the research of domestic and foreign research present situation of the echnology of seismic reservoir prediction systematically, as well as the main method of the seismic reservoir prediction method, principle, including the petrophysical analysis and seismic response, seismic facies analysis, discussing the principle and method of seismic attribute analysis technology, and the extraction and optimization method of attribute is analyzed and researched, discussing the principle and method of seismic wave impedance inversion, and put the emphasis on recommending the analysis of logging constrained seismic inversion and so on, in order to realize its application in exploration.This article combines with production practice, on the basis of research on seismic reservoir prediction method, with Jinjiachang field area as the research object, combined with the earthquakes, geological and logging data in this are, On the basis of detailed reservoir calibration and on segments Ⅱ, Ⅲ oil group sedimentary microfacies as a guide, by adding sand to sand experiment, seismic facies and seismic attribute analysis, wave impedance inversion method of new sand body to carry out seismic reservoir prediction research, clear the distribution rules of sand body, preliminary forecast gold field in basalt, permeability sandstone developed areas, to further clarify the exploration potential of the region.
