| 摘 要： | 以准噶尔盆地腹部陆西地区三个泉凸起的陆15井区油藏为例,通过分析断层封闭性,结合地质背景,分析了不同性质和规模断裂在油气成藏中的作用。结果表明,区内陆2井北断裂现今封闭性较好,陆15井南断裂现今封闭性较差,前者早期输导、现今封闭是油气成藏的关键控制因素;断距较大的生长型断层决定油气的空间分布,而油藏内部断距较小的幕式活动断层对油气保存影响很小。 |
| 关 键 词： | 准噶尔盆地 三个泉凸起 断层封闭性 油气成藏 |

| Abstract: | Taking Wellblock Lu-15 in Sangequan swell of western Luliang uplift in hinterland of Junggar basin,the fault sealing and the process of different faults in property and scale are analyzed in hydrocarbon accumulation.The results show that that the fault in northern Well Lu-2 is good in sealing property for its early transport and present sealing as critical controlling factors,while the fault in southern Well Lu-15 is poor.The distribution of oil and gas in space is mainly controlled by the growth faults with large throw,while episodic faults with small throw in a reservoir is of few influnce on the oil-gas preservation in this area. |
| Keywords: | Junggar basin Sangequan swell fault sealing hydrocarbon accumulation |
