摘要
琼东南盆地在早第三纪晚期,处于海侵逐步扩大的古地理环境。在这一背景下,崖13-1地区发育了陆源冲积扇-河流-扇三角洲沉积体系,逐步过渡为三角洲体系,并受一定潮汐营力的影响。崖13-1气田正处在三角洲前缘砂体及河道砂体的位置,从而提供了良好的储集层条件。

Hainan basin was in a paleogeographic environment of gradually transgression, under which a sedimentary system of terrigenous alluvial fan-river-fan delta was developed in the YA 131 area and evolved later into a tidal modified delta system. Delta—front sands and channel sands of the systems act as fine reservoirs for the YA 13—1 gasfield.
