Quantitative evaluation on hydrocarbon favorability of the first member of Dainan Formation at Yong'an area of Gaoyou Sag based on Logistic regression model
摘要
Abstract
A quantitative hydrocarbon favorability evaluation was desirable for enhancing oil and gas exploration of the first member of Dainan Formation at Yong'an area, Gaoyou Sag. After subdividing the evaluation units and screening the evalua-tion variables in terms of the current exploration results, a new model for quantitative hydrocarbon favorability evaluation was built by employing a logistic regression method to find the relationship between the hydrocarbon occurrence and geological variables. Based on the established model, multi-level hydrocarbon favorability was then characterized systematically and some exploration strategies were promoted combining the cognition of petroleum geology. The results show that the logistic re-gression model of hydrocarbon favorability built in application is reliable with model accuracy up to 89%. The deep part of the study area is deemed favorable for future hydrocarbon exploration. The logistic regression method presented here has good adaptability without heavy restrictions. This hydrocarbon favorability evaluation using logistic regression method can not only derive the probability of hydrocarbon occurrence directly, but also reveal the variations of hydrocarbon favorability convenient-ly, which would be useful for exploration planning.关键词
