通过对盆地构造沉积演化和地质条件进行分析,结合典型油气田勘探实例,对研究区盐下层系的油气成藏主控因素进行分析。认为碳酸盐岩台地和斜坡区发育的礁滩相储层为大型油气田的形成提供了有效储集空间,巴什基尔末期的构造抬升运动造成的风化淋滤作用改善了储集层的储集性能,不整合面和断裂构成了良好的运气运移通道。北部-西北部断阶带KT-2储集层段具有较大的勘探潜力。 By analyzing the sedimentary evolution and geological conditions of the basin structure and combining with the typical oil and gas field exploration examples, the main controlling factors of the hydrocarbon accumulation in the salt strata in the study area are analyzed. It is considered that the reef-shoal facies reservoirs developed on the carbonate platform and slope area provide an effective reservoir space for the formation of large-scale oil and gas fields. The weathering and leaching action caused by the tectonic uplift movement in the Bashkir period has improved the reservoir storage Set of performance, unconformity and fracture constitute a good luck transport channel. The north-northwest fault zone KT-2 reservoir has great exploration potential.
