STRUCTURAL FEATURES OF JUNGGAR TARIM AND TURPAN-HAMI BASINS XINJIANG AND THE DISTRIBUTION OF OIL AND GAS

新疆三大盆地总面积为73 8×104km2,均属多类型叠加复合型盆地,经历了古生代和中、新生代两大旋回和6个演化阶段,具多个不同类型的不整合,构造样式丰富多彩。油气分布主要受控于古隆起、古斜坡、区域不整合和各类低序次扭动构造带。

The Junggar,Tarim and TurpanHami Basins with total area of 738×104km2 belogn to superimposed composite basin.They underwent six evolution stages in Paleozoic and MesoCenozoic cycles,having different Qinds of unconformities and a variety of structural styles.The distribution of oil and gas is controlley by ancient uplift ancient slope,regional unconformities and kinds of primary generations of structural types.
