Exploration Benefit Method Principle and Its Application in the Prediction of Oil and Gas Resources

As the oil and gas exploration advances,more and more oil and gas resources are discovered and the uncovered oil and gas resources underground are less and less.How to predict the exact oil and gas resources in the mature exploration area is the focus of the petroleum investors and the oil and gas resources evaluation workers.This paper discusses at length the principles of the exploration benefit method and its application and problem in oil and gas resources evaluation.Its application in Gaoyou Sag of Subei Basin shows that the oil and gas reserve uncovered in the Gaoyou Sag is about 6 773×10~4 t.The operating practice of the exploration benefit method proves that the exploration benefit method slides over the problem of oil and gas genetic mechanism in reason and reduces the subjective impact on oil and gas resources evaluation effectively,which makes the results of oil and gas resources evaluation more objective.
