Log Evaluation of Permian Marine Carbonate Reservoir in Sichuan Basin
摘要
Abstract
The Lower Permian carbonate reservoirs in Sichuan Basin is the key exploration target. Unlike the reef carbonate of upper Permian,unconformity cave-cleft bodies and hydrothermal dolomite of lower Permian Maokou Formation,the reservoir type of high-energy beach in the Maokou Formation is more complicated.Based on the comparison and analysis of several reservoir characteristics,the calculation methods of porosity and saturation are established according to different reservoir types,different pore intervals and different conditions of permeability in reef reservoirs.In view of the Maokou Formation high-energy beach facies reservoir,the changes of sedimentary microfacies and the relationship between rock mineral composition and structure of"calcilutite"reservoir are analyzed.T hen the pore space types and distribution characteristics of reservoir are described by logging information, the multiple mineral volume model was constructed to calculate the mixed rock matrix values point by point.Furthermore,the mineral composition and porosity of the reservoir are calculated.T herefore,the"calcilutite"reservoir parameter calculation precision is improved.T he method has good application effect according to the core test and gas test and show s a good application prospect.关键词
