【摘要】 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。更多还原

【Abstract】 In recent years, prolific reservoirs in lower Ordovician. Were discovered in the Tazhong Ⅰ break zone (wells TZ-58 and TZ-82), the Lunnan oil field(wells LG-15 and LG-63) and the Tahe oilfield (wells T402 and T606) in the Tarim basin. However, the karst reservoirs and traps are complex, and understanding of distribution and formation of reservoir is on its infant stage.To find favorable area for petroleum exploration, the special seismic reflector of the lower Ordovician in KA-1 3D seismic area of Katake uplift has been studied, and correlated with karst reservoirs that have found in lower Ordovician.更多还原
