Geological Research And Exploration Of The High-profile Area Favorable Area Forecast

Sub-region of North oil field belonging to extend the high-profile group，it has largeexploration area and relatively low degree of exploration。In order to further enhance theexploitation rate of the field，people should first understand the situation and the developmentof geological exploration of the status quo of the study area，and then the main reservoir forproper division and correlation，combined with a series of techniques to study the reservoircharacteristics and the type of sedimentary facies。Capable of rational use of reservoirmodeling software to fit various small layers of history to accurately simulate thethree-dimensional geological model of the reservoir。Conducting research area logginginterpretation model of reservoir parameters，using target layer core analysis and logging data，perform basic data management， establish the required parameters to explain reservecalculation and prediction models。Then grasp the scope of vertical reservoir sand bodieswithin the reservoir，developmental characteristics of the lateral distribution rules andmicrofacies，the main river in the area looking to find a favorable oil region，to provideresources for the development of the region to succeed。At present，more effective way to predict favorable area is reasonably divided strata，theapplication of sequence stratigraphy theory as a guide to compare strata，such as establishing astratigraphic framework；followed isochronous within this framework，the application ofmodern sedimentology and reservoir methods and principles to study the sedimentary layers ofsedimentary microfacies，find and study the reservoir；again combined oil and gas migrationcontrol factors，such as micro-structural study reservoir formation，summed hydrocarbonaccumulation； Finally，this rule of conduct oil and gas distribution predict favorable areas。...
