The Study Logging Reservoir In Badin Area Of Lower India River Basin Evaluation

The petrophysical property and lithology of Cretaceous reservoirs in Badin area of lower India River Basin are obviously different,and the rock electric properties of oil and water layers are small.In the thesis,a large number of core,oil testing data and logging interpretation theory were applied to study logging reservoir evaluation method in Badin area.According to the logging data,through the analysis of the geological structure,sedimentary characteristics of Badin block,single well and well facies division of Badin block,and further in-depth study of the Badin reservoir four property relations and its characteristics were studied.Using natural gamma logging and experimental data fitting determined the clay content in Badin.The natural gamma,acoustic logging,combined with the establishment of Badin area porosity interpretation model,combined with the experimental data of rock electricity,and determined the Badin area of cementation exponent m and saturation exponent n electrical parameters.Comparison of variable Archie formula and J function,the establishment of oil saturation model suitable for the study area;with Badin logging,logging and oil test data,explore the logging environment under different fluid sensitive parameters to determine the block study area of different layer of the oil and water interface,the establishment of Badin area reservoir fluid identification plate.Finally,combined with the actual production of the study block,a set of theory for logging reservoir evaluation in Badin area is summarized,which provides reliable technical support for Badin block in the lower India River basin.
