摘要:
辽阜地2井是阜新盆地油气勘探以来第一口高产工业油流井，抽汲试采日产油15.3 m3.通过分析辽阜地2井钻遇下白垩统的岩石组合特征，结合部分测井曲线以及油层深度，明确了阜新盆地下白垩统沙海组下段、沙海组上段、阜新组和孙家湾组的岩石组合及测井曲线形态特征，建立盆地1200 m以内具有成功油气开发经历钻孔地层综合柱状图，为今后阜新盆地的油气勘探开发研究和地层划分对比提供参考和借鉴.
Abstract: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.
