Title: On Well Logging Technology to Quickly Evaluate Productivity of the Ultra-low Permeability Reservoir
Abstract: Generally it's hard to evaluate productivity of Ordos basin ultra-low permeability reservoir using traditional methods,so we derived new parameters sensitive to reservoir productivity from primitive logging parameters,which are thickness parameter,lithology parameter,physical property parameter,oiliness parameter and I TP( Three Porosity Index) index. We set up three fast prediction methods such as logging curve characteristics,weighted coefficient of energy storage and DM( Data Mining),and analysis on their characteristics are conducted. Eventually formed is the technology to quickly evaluate capacity of the ultra-low permeability reservoir. Practical application of this method in Ordos basin Chang6 reservoir shows that the productivity evaluation coincidence rate reaches 85%. This technology provides a basis for developing ultra-low permeability reservoirs.
