摘要
惠民凹陷是济扬坳陷主要生油凹陷之一,是典型的陆相断陷盆地。基山砂体是惠民凹陷在断陷期发育的一套物源来自于西北部宁津凸起的三角洲—浊积扇沉积体系;分布范围广,横跨滋镇洼陷、中央隆起带和临南洼陷田家一带;主体沿着宿安沟呈西北向东南方向展布,在临商地区发育类型丰富的油气藏,具有巨大的勘探潜力。近年来基山砂体油藏勘探取得较大成功,但砂体的物源、沉积相一直是争论的焦点,本文主要针对这2点进行了探讨,并将研究结论应用于勘探实践中,取得了显著的效果。
Huimin depression, which is one of the main oil depressions, is a typical terrestrial downfaulted basin. The Jishan sand bed is a delta that originated from northwest Ningjin Rise at the downfaulted period of Huimin depression. Stretching across Zizhen depression, the central upwarping zone and Tianjia zone of the Linnan depression, it is widely distributed. Its main body stretches from northwest to southeast along Su'an trench, and an enriched oil and gas storage was developed in Linshang region, which has great exploitation potential. The exploration in the area has achieved much success, but the origin and sedimentary faces of the sand bed are still disputed, hence, we give some discussions.
