The paper closely combines research projects: fine reservoir description of Su20 Block main oil-bearing formation Shihezi sets in Sulige explore area. Based on main thinking of facies-seismic constraint fine reservoir description research, with tectonic fine explanation, fine seismic-facies identification, seismic Spectral-Deconversion information, seismic attributes optimization, AVO attribute inversion, pre-stack geophysics attribute inversion, seismic-facies constraint geological model technologies and so on, by integerated research ideal of stratigraphic sequence correlation and reservoir character research, geology-seismic tectonic fine interpretation, geophysics constraint fine seismic facies identification and partition, mul-laminated sand clay identification and quantity forecast, AVO attribute inversion and forecast, pre-stack elastic attribute analysis and oil-bearing reservoir forecast and seismic-facies constraint geology model, and focusing on seismic attribute and geological facies, it all-around expatiates the last technology headway and innovation of fine reservoir description in the key exploration & development steps, and get hold of series effective technologies of fine reservoir description focusing on complicated geology background. By application of research job, It gains maked geology and drilling effect, and use for reference and important value for exploration & development in Oil-field.Base on analysis of mul-laminated sand-clay seismic reflectance character and dynamic character, it system describes geology meaning and essential ideal of seismic Spectral-Deconversion imaging. The last drilling results indicates seismic Spectral-Deconversion imaging technology to research time-space disciplinarian of aggradations unit and foundation of aggradations mode, estimate of discriminability reservoir thickness and prediction of mul-laminated sand-clay. The forecasted result is the time-space disciplinarian and the plane character of rivalway sand body, secondly it is important direct signification for exploration and development.ptimizes to choice intercept P, grads G,νand flow factor parameter of AVO attribute inversion to forecast reservoir thickness, penetrability sand thickness and porosity. The reRelying on oil-bearing reservoir geophysics character, the rule of AVO attribute inversion fear-near shot sets and clustering-distinguish analysis technology, the paper osult provides important evidence for optimized choice and layout of Su20 development Block and it gains maked drilling result.
