摘　　要：依据基准面旋回原理和方法,综合利用哈得逊地区的钻井、测井、地震以及地球化学资料,在研究区下石炭统识别出1个Ⅰ型和3个Ⅱ型层序界面,将哈得逊地区下石炭统划分为3个中期基准面旋回:SC_1、SC_2、SC_3,对应于早石炭世海侵的3个海进-海退旋回。SC_1旋回以滨岸砂坝沉积为主,而SC_2、SC_3旋回发育潮坪沉积体系。研究认为,SC_1旋回滨岸砂岩及SC_2下降半旋回的潮间带薄层砂岩为有利储集砂体,是地层-岩性型油气藏的重点勘探目标。Based on principle and methods for base level cycle, the drilling, well logging, seismic and geochemical data from Hadexun area are analyzed. One I-type and three II-type sequence interfaces of Luwer Carboniferous are recognized, and three medium-term base level cycles （SC1, SC2, SC3） corresponding to three transgressive-regressive cycles are classified. SC1 cycle is dominated by longshore bar deposit, while SC2, SC3 by tidal flat system. The study shows that SC1 sandstone and SC2 flagstone are favorable reservoir sand bodies and could be as key targets for exploration of stratigraphic and lithologic oil-gas pools.
