Reservoir characteristics research and logging evaluation of Chaiwopu 3D area

On the basis of coring data,log data and laboratory analytical data analysis,by using core scale logging analysis technique,the lithology identification criterion and interpretation models on porosity and oil saturation of Hongyanchi fomation have been established.In combination with oil tesing and water tesing data,the hydrocarbon identification criterion of Hongyanchi formation in Chaiwopu3D area has been confirmed,which provides scientific guidance for improving exploration and development of the area the whole basin.
