近年来,塔里木盆地塔中Ⅰ号断裂坡折带(塔中58井、塔中82井)、塔北地区轮南油田(轮古15井、轮古63井)、塔河油田(塔河T402井、塔河T606井)在下奥陶统获得高产工业油气。然而,卡塔克隆起卡1三维工区奥陶系岩溶储层及圈闭复杂,对油气藏形成与分布规律的认识和油气勘探尚处在探索阶段。本文分析了卡塔克隆起卡1三维工区下奥陶统特殊地震反射体特征,并与已经发现的下奥陶统岩溶油气藏的特征进行了对比,预测了有利勘探目标。
In recent years, the Tazhong Ⅰ fault slope break zone (Tarim 58 well and Tazhong 82 well) in Tarim Basin, Lunnan Oilfield (Rotoru 15 well and Lungu 63 wells) in Tarim Basin, Tahe Oilfield (Tahe T402 Well, Tahe T606 well) to obtain high-yield industrial oil and gas in the Lower Ordovician. However, the Catac climates the Ordovician karst reservoirs and traps in the three-dimensional work area of Card 1, and the understanding of formation and distribution of oil and gas reservoirs and oil and gas exploration are still under exploration. In this paper, we analyze the characteristics of the Lower Ordovician special seismic reflector in the three-dimensional Katarikataka 1 work area and compare it with the characteristics of the Lower Ordovician karst reservoirs that have been discovered, and predict the favorable exploration targets.
