红山嘴地区是准噶尔盆地西北缘重要的油气聚集区。经过多年的油气勘探，在该区三叠系地层中已发现多个油藏，但是该区地质条件复杂，影响油气成藏的因素较多。在对红山嘴地区油气藏特征研究的基础上，提出了2个油气成藏主控因素: 断裂对油气运聚具有十分重要的作用，沉积岩相控制着油气藏的规模和分布。通过主控因素研究，提出了红山嘴地区三叠系地层的勘探潜力。

Hongshanzui Area is an important hydrocarbon accumulation zone of the northwestern margin of Junggar Basin. After the oil
exploration of many years, many reservoirs were detected in the Triassic formation. Because of the complicated geological conditions
in this area, there are many factors affecting hydrocarbon accumulation. Based on the research of hydrocarbon reservoir
characteristics in Hongshanzui Area, we put forward two main controlling factors of hydrocarbon accumulation. They include that the
fractures play a remarkable role in the hydrocarbon migration and accumulation and that the size and distribution of hydrocarbon
reservoir are controlled by sedimentary facies. We proposed the exploration potential of Triassic formation in Hongshanzui Area by
the research of main controlling factors.
