2. tazhong ancient uplift originated from normal fault in paleozoic, hydrocarbon formed in ordovician period, structure reverse made tazhong uplift form from the middle ordovician period to the late ordovician period, and it provided geologic background for the deposit of silurian - devonian stratum. tazhong uplift formed at the end devonian, ancient reservoir was destroyed and asphaltum sandstone formed, structure deformation more destroyed ancient reservoir in early permian, after then the major of structure deformation is regulation
塔中隆起源於早古生代拉張背景下的正斷層,寒武-奧陶紀為其烴源
巖形成的重要時期;早奧陶世末-晚奧陶世末的構造反轉是塔中隆起的主要形成期,同時也為志留系形成地層及復合圈閉提供了古地理背景;志留?泥盆紀塔里木盆地南北緣均轉為活動大陸邊緣,形成了大量的斷裂和不整合;泥盆紀末塔中鼻狀隆起基本定型,古油藏遭受破壞,形成了瀝青
砂巖;早二疊世晚期的構造變形使古油藏遭受進一步的破壞;二疊紀后構造變動主要以調節為主。
