| 摘 要： | 吐哈盆地台南凹陷鲁克沁构造带中的北西走向断层受挤压强烈 ,封闭性好 ;而北东走向断层封闭性差 ,常成为油气运移的良好通道。由于本区断块圈闭的有效性差 ,故不具备大规模聚集稀油的条件 ,但对稠变到一定程度的稠油能起较好的封堵作用。鲁克沁构造带高粘重质油的形成是原油运移和成藏阶段双重稠变作用的结果 ,并且油气的聚集是一个动态的过程。随着原油的逐渐稠变 ,所需要的封堵条件逐渐降低 ,油气的聚集过程才趋于稳定。鲁克沁构造带构造后期变革主要表现在构造幅度的增大 ,而未发生强烈的断裂作用 ,因此 ,前侏罗系油藏得以完好地保存

| Abstract: | The evolution of fault sealing property is analyzed by using the calculation of the normal stress on the fault surface. The fault sealing in northwest orientation is good, and that of northeast orientation is poor during oil migration. The validity of fault sealing is low in this area. So light oil can not be accumulated normally, but heavy crude can. The heavy crude has been thickening during migration and accumulation period in Lukeqin structure belts. The condition for fault sealing is lowering with the thickening of heavy crude, and hydrocarbon accumulating process gets to be stable. Because the main feature of tectonic movement is not strong fracturing after hydrocarbon formed, the oil reservoir of Jurassic period is preserved. |
