下扬子区皖南地区含油气系统分析

Analysis of Oil-gas Bearing System in South Anhui Province of Lower Yangtze Region

利用BASIMS盆地模拟软件 ,通过对下扬子区皖南地区的盆地模拟研究 ,对该区从纵向上划分出三套含油气系统 ,并对这三套含油气系统从烃源 (晚期生烃 )、晚期成藏、有效保存三个关键因素出发 ,通过三套含油气系统四个关键时刻的平面评价分析 ,评选出有利勘探地区 ,主要在上古生界及中新生界保存较好的地区 :宣州—南陵、芜湖、潜山—望江和休宁四个地区。

By using SASIMS basin simulation soft wares, and through basin simulation studies of the south Anhui Province in Lower Yangtze region, three suite of oil-gas bearing systems are plotted out longwise, and analyses on the three key factors of hydrocarbon sourced rocks, late mineralization and effective storage are made. Favorable exploratory zones are elected, they are:Xuanzhou to Nanling, Wuhu, Qianshan to Wangjiang and Xiuning, the four well-preserved regions in upper Paleozoic and middle Cenozoic.
