Research And Application Of Reservoir Prediction Technique Based On Stacked Data

In recent years,through continuous research shows Baikouquan of Mahu depression in Junggar Basin hydrocarbon accumulation controlled by favorable facies,noses and broken joint structure.By drilling,the entire slope and depressed area initially show a whole reservoir characteristics.However,as in the past Baikouquan depositional systems research is based on group and segment as a unit,it is difficult to resolve the differences between multiple groups in Baikouquan periods.And conventional sand comparing method may easily lead to phenomenon that make different periods of sand layer as the same layer of sand bodies.Eventually leading to the deposition of the times,the space overlying relationship is unclear,so that the complex nature of the reservoir.In order to accurately portray the Triassic Baikouquan groups favorable sedimentary facies and sand body spatial overlay feature,look for favorable stratigraphic and lithologic traps target,in this article,using a variety of geophysical methods of new technologies,including high-resolution stratigraphic track technology,seismic modeling technology,OVT multi-faceted field curvature extraction technology,multi-attribute analyzing,high accuracy sequence constraint inversion technique to evaluate the fan in Maxi slope area.First,the basic geological features of Maxi slopes area were studied.On the basis,re-evaluate an re-process the log data and seismic data;Secondly,do fine structural interpretation of seismic data,especially for late as inversion constraints,using high-resolution sequence stratigraphy interpretation techniques,establish a well-seismic unified high-precision and isochronous sequence of stratigraphic framework.In order to identify small fault throw,using seismic modeling conducted for guidance on interpretation.At the same time the using the technology of curvature extraction method based on OVT Azimuth field to enhance the identification;then,by seismic modeling techniques to identify different reflection characteristics of sedimentary facies zone;Finally,through the use of multi-attribute analysis portray favorable lateral facies distribution,by the use of acoustic impedance improve inversion longitudinal prediction accuracy of sand bodies.Eventually get the purposes of favorable reservoir prediction.
