| 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：SC1、SC2、SC3,对应于早石炭世海侵的3个海进-海退旋回.SC1旋回以滨岸砂坝沉积为主,而SC2、SC3旋回发育潮坪沉积体系.研究认为,SC1旋回滨岸砂岩及SC2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.

| Abstract: | 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 Lower Carboniferous are recognized, and three medium-term base level cycles (SC_1, SC_2, SC_3) corresponding to three transgressive-regressive cycles are classified. SC_1 cycle is dominated by longshore bar deposit, while SC_2, SC_3 by tidal flat system. The study shows that SC_1 sandstone and SC_2 flagstone are favorable reservoir sand bodies and could be as key targets for exploration of stratigraphic and lithologic oil-gas pools. |
