火山岩油气藏已经成为准噶尔盆地西北缘油气勘探开发挖潜的一种重要类型,但卡因迪克地区石炭系火山岩至今尚未获得突破。通过深入剖析周边地区石炭系火山岩油气藏类型、储层及盖层特征,深化认识了火山岩在复杂构造带上的成藏规律,初步确定构造条件、岩相特征、裂缝发育程度和保存条件为油气成藏的4个关键因素,并通过对比预测了卡因迪克地区石炭系火山岩成藏的可能性。
Volcanic reservoirs have become an important type of potential exploration for oil and gas exploration and development in the northwestern margin of the Junggar Basin. However, no breakthrough has ever been made in the Carboniferous volcanic rocks in the Cainediq area. By deeply analyzing the types of Carboniferous volcanic reservoirs, the features of reservoirs and cap rocks in the surrounding areas, we deepened our understanding of the laws of volcanic accumulation on complex structural zones, and initially determined the tectonic conditions, lithofacies characteristics, degree of fracture development and the preservation conditions for oil and gas 4 key factors of hydrocarbon accumulation, and predicted the possibility of hydrocarbon accumulation in Carboniferous volcanic rocks in Cainedike area through comparison.
