LITHOSTRATIGRAPHIC CHARACTERISTICS OF LFD-2 WELL IN FUXIN BASIN

The LFD-2 well was the first high-yield commercial oil flow well since the oil-gas exploration in Fuxin Basin, with a daily swabbing production of 15.3 m³. By analyzing the characteristics of Lower Cretaceous rock assemblages in the drill hole, combined with some of logging curves and reservoir depth, the paper identifies the rock assemblages of lower and upper members of Shahai Formation, Fuxin Formation and Sunjiawan Formation, as well as the characteristics of logging curves, and sets up a comprehensive stratigraphic column of borehole with successful oil-gas development experience within the depth of 1200 m in the basin, which will hopefully provide reference for future oil-gas exploration and development, and stratigraphic division-correlation in Fuxin Basin.
