1简介春光区块位于位于准噶尔盆地西部隆起南部车排子凸起东侧,构造面貌相对较为简单,呈东南倾的单斜,面积约1023.3km 2。自下而上发育了石炭系、白垩系、古近系、新近系、第四系地层,局部有侏罗系部分地层沉积,缺失二叠系、三叠系全部地层。其中石炭系岩性以凝灰岩等火成岩为主。准噶尔盆地相继在石炭系取得重大突破,发现了石西油
1 Introduction The Chunguang block is located to the east of Chepaizi uplift in the southern part of the uplift of the Junggar Basin. The structure of the block is relatively simple with a monoclinic southeast dip with an area of about 1023.3km 2. From bottom to top, the Carboniferous, Cretaceous, Paleogene, Neogene and Quaternary strata developed. Some strata of Jurassic strata were locally deposited, and all of the Permian and Triassic strata were missing. Carboniferous lithology is dominated by tuff and other igneous rocks. The Junggar Basin made significant breakthroughs in the Carboniferous, one after another, and discovered Shiqi Oil
