准噶尔盆地是我国最早发现油气的沉积盆地之一，自1955年发现克拉玛依油田以来，已探明30多个油气田。通过对盆地地质特征、成藏机制以及储量分布特征分析，重点探讨了近年来盆地快速、高效勘探的成功经验，并以油气储量发现为主线，结合盆地勘探程度和储量增长变化趋势，预测了盆地未来储量增长和勘探潜力。目前盆地油、气探明程度为45．3％和30．3％，正处在中期—中晚期勘探阶段，预测还应有（9．42～16．92）′108 t的石油地质储量待探明；岩性、火山岩、致密砂岩等隐蔽性油气藏是盆地今后油气勘探的主要目标。
準噶爾盆地是我國最早髮現油氣的沉積盆地之一，自1955年髮現剋拉瑪依油田以來，已探明30多箇油氣田。通過對盆地地質特徵、成藏機製以及儲量分佈特徵分析，重點探討瞭近年來盆地快速、高效勘探的成功經驗，併以油氣儲量髮現為主線，結閤盆地勘探程度和儲量增長變化趨勢，預測瞭盆地未來儲量增長和勘探潛力。目前盆地油、氣探明程度為45．3％和30．3％，正處在中期—中晚期勘探階段，預測還應有（9．42～16．92）′108 t的石油地質儲量待探明；巖性、火山巖、緻密砂巖等隱蔽性油氣藏是盆地今後油氣勘探的主要目標。

The Junggar Basin is one of early explored petroliferous basins in China. Since the discovery of the Karamay Oil Field in 1955, over 30 oil fields have been found. The geologic features, hydrocarbon accumulation mechanisms and distribution characteristics of the Junggar Basin were studied in this paper. The basin has under?gone rapid and effective exploration in past years, which helped potential prediction. The present estimate of re?coverable oil and gas resources in the basin is 45.3% and 30.3%, respectively. Exploration is in the middle and late stages. There are (9.42~16.92) ×108 t oil remaining unproved. Lithologic, igneous rocks and tight sand?stones are the main targets for future exploration in the basin.
