Analysis of Oil-water Distribution Law in Gulong Syncline Area of Southern Gulong

In order to find the main control factors that affect oil-water distribution in Gulong syncline, the oil-water distribution law and main control factors of Gulong syncline in Gulong South were analyzed based on comprehensive evaluation. The research shows that Putaohua oil reservoir in Gulong syncline area of southern Gulong is mainly lithologic oil reservoir under structural background, and the distribution law of oil and water is controlled by structure, sedimentation and reservoir physical properties. The distribution characteristics of reservoir physical properties are the main factors that control the distribution of oil and water in this area. This paper optimizes the reserves on the basis of recognizing the distribution of oil and water, and finally delineates the area of the well potential area X.Xkm2.
