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。
In this paper, we use the comprehensive method of seismic, geology and gravity to systematically study a large number of structural large-scale sections traversing the basin-mountain structure in the study area, especially the in-depth anatomic analysis of the Kekeya oil and gas structure that passes through the known oil and gas fields The basin-mountain tectonic model of the Fu-Sha-Kriyang region (composed of three major tectonic systems: one is the recoil slip system; the other is the deep reverse thrust wedging system; and the third is the thin-skin nappe system). Based on the tectonic analysis of the whole area, the tectonic framework of the area is deduced (based on the tectonic zone of “Yuli Group - the first row of Keliyang anticline”, the basin-to-basin system to the north and the thin-skinned area to the south Retired off-site system). The controlling factors of oil and gas in Kakya oil and gas field are analyzed, and the favorable zones for oil and gas exploration are proposed.
