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.

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 undergone rapid and effective exploration in past years, which helped potential prediction. The present estimate of recoverable 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 sandstones are the main targets for future exploration in the basin.
