摘　　要：采用地震、地质、重力相结合的综合方法，对研究区域多条穿过盆山构造带的构造大剖面进行系统研究，特别是对穿过已知油气田的柯克亚油气构造的深入解剖分析，建立了甫沙－克里阳地区的盆山构造模式（由三大构造体系组成：一是反冲滑脱系统；二是深层逆推楔入系统；三是薄皮推覆系统）。在对全区构造分析的基础上，推论了该区的构造格局（以“玉力群－克里阳第一排背斜构造带”为界，以北为盆地原地系统，以南为薄皮推覆异地系统）。分析了柯克亚油气田的油气控制因素，提出了油气勘探的有利区带。Synergistic methods combining seismology geology and gravity were used to study systematically the major structural profiles crossing the basin mountain belts in the study area． In particular the author made a profound analysis of the Kekeya hydrocarbon bearing structure crossing the known oil and gas field and established the basin mountain structural mode of the Fusha－Keliyang region which comprises three large tectonic systems thrust decollement system deep layer thrust wedge system and the thin skinned nappe system． On the basis of analysis on the whole region structure the author deduced that the structural framework of this region is bounded by the first row of anticline structural belt of Yuliqun－Keliyang with basinal autochthonous system to its north and thin skinned nappe allochthonous system to its south． The paper also analyzed the hydrocarbon controlling factors of the Kekeya field and established favorable play．
