Sedimentary Process and Reservoir Characteristics of Turbidite Fan of Cretaceous Yageliemu Formation in Kuqa Foreland Basin

摘要: 通过对库车前陆盆地西部卡普沙良河剖面上侏罗统喀拉扎组—下白垩统亚格列木组沉积相垂向演化分析、砂泥岩X射线荧光光谱分析、储层微观特征研究，认为喀拉扎组—亚格列木组发育一套干旱气候背景下的陆上季节性辫状河—半深湖浊积扇—浅湖相的沉积演化序列。上侏罗统喀拉扎组主要以季节性辫状河沉积为主，下白垩统亚格列木组下部发育早晚两期浊积扇沉积，浊积扇水道砂体中见槽模、沟模以及重荷模，并发育典型的鲍玛序列，该沉积时期的古气候偏干冷；亚格列木组上部主要发育浅湖相泥岩与沙坝沉积，此沉积时期古气候由湿热变化至干冷。亚格列木组浊积扇水道砂体中石英含量较高，一般介于62%~70%之间，粒间溶孔与构造缝较发育；浅湖相沙坝砂体石英含量降低，一般为55%~58%，沙坝砂体中溶蚀孔较浊积扇中溶蚀孔多。亚格列木组中浊流沉积的发现，不但丰富了库车前陆盆地重力流沉积的研究成果，也表明在早白垩世库车西部发育较深水的沉积环境，为该地区湖相深水沉积的油气勘探奠定了基础。

Abstract: Sedimentary process, Xrays fluorescence analysis of sandstone and mudstone, and reservoir characteristics analysing were used in measuring the strata of Kapushaliang outcrop in Kuqa foreland basin. An evolution of sedimentary process is obviously in dry climate. Intermittent braided river deposits in Upper Jurassic Kalazha Formation. Turbidite fans develope in lacustrine deep water of Lower Yageliemu Formation, and shallow water lake mudstone and lacustrine bars deposit in Upper Yageliemu Formation. The dry and cold paleoclimate occurs in early period of Yageliemu Formation. At the same time, some sedimentary structures for examples the groove cast, flute cast, gravity markers, and Bouma sequences deposit in turbidite fan channels. The black lacustrine mudstone developes in the upper Yageliemu Formation, the paleoclimate changes from warm to cold. The quartz percentage of turbidite fan channel is higher than lacustrine bar. The value of tuibidite fan channel is from 62% to 70%, and the value of lacustrine bar is from 55% to 58%. There are some solution opening in sandstones of tuibidite fan channel and lacustrine bar, but the solution value of lacustrine bar is higher than turbidite fan channel. The discovery of turbidite fan in Kapushaliang outcrop of Yageliemu Formation is important for foreland basin research in Kuqa, and instructs lacustrine deep water region development in the western Kuqa depression.
