Abstract:

According to the implement "Criterion of Resource Evaluation of Major Hydrocarbon Basin" implemented by the PetroChina Company Limited and the recommended system of hydrocarbon resource evaluation,the key factors influencing the resource evaluation were emphatically analyzed,in combination with the characteristics of Nanpu Sag.The geologic evaluation of basin was made by taking hydrocarbon system as the evaluation unit.Geologic evaluation of hydrocarbon distribution play was made by using geologic risk analysis.In the analysis of Gaoliu and Laoyemiao areas,the resources were calculated by using the statistical method,including the reservoir scale sequence,saturation exploration well and trap summation methods.The resources of plays were calculated with the genesis method and analogy method including the oil supply unit and analogy of area abundance. The final resources for each play were received by using Delphi forecasting method. The resources of Nanpu Sag were obtained by summing the resources of each play. Compared with the previous resource evaluation method,the combined evaluation technology of genesis,statistic and analogy methods is more objective for the resource evaluation.

Key words: geologic evaluation, oil and gas resource, reservoir scale sequence method, saturation exploration well method, area abundance analogy
