为深入查明查干凹陷西部次凹苏红图期和巴音戈壁期构造转换带对油气富集的差异控制作用,研究通过对古构造的分析以及生长断层的恢复,阐明了构造转换带类型,认为查干凹陷西部次凹构造转换带类型丰富,尤以同向平行型转换带、相向平行型转换带、同向叠覆型转换带为主要转换带类型。并揭示了构造转换带的控制分布规律。进而明确构造转换带对沉积、储层、构造圈闭以及输导体系的差异制约作用,认为列状接近型转换带、平行型转换带为有利的油气富集带,查干凹陷西部次凹巴润中央构造带北部为油气有利富集区。
In order to further understand the difference control over the enrichment of oil and gas in the sub-depression Su-red map and Bayinogou-period tectonic transformation zone in western Chagan depression, the paper analyzes the palaeotectonics and the recovery of the growth faults, It is believed that the structural transformation belts in the western sub-depression of the Chagan Depression are rich in type, especially the same type of parallel transition zone, the parallel parallel transition zone and the same-direction superimposed transition zone. The rules of control distribution of structural transition band are revealed. Furthermore, it is clear that the structural transition zone has a great effect on the sedimentation, reservoirs, tectonic traps and the differential control of the transport system. It is considered that the adjacent transition zone and the parallel transition zone are beneficial oil and gas accumulation zones, Run central tectonic zone in the north for the oil-rich enrichment zone.
