摘要(Abstract)：
头台地区泉四段属曲流河三角洲和湖泊沉积体系,曲流河三角洲相分为三角洲平原和三角洲前缘2种亚相,湖泊相分为滨湖和浅湖2种亚相。自下而上沉积环境的演变过程为三角洲平原—三角洲前缘—浅湖,反映了泉四段沉积时期盆地水体逐渐加深的过程。沉积微相以分流河道微相最为发育,其砂岩是有利的储集层。由于分流河道间发育,其泥岩常常包裹或覆盖分流河道砂、河口坝和薄层砂等砂体,形成良好的储盖组合,有利于形成岩性圈闭油气藏。
The deposition of Quan4 Member in Toutai area belongs to meandering-delta and lacustrine deposition system.Meandering-delta facies can be divided into delta plain subfacies and delta front subfacies,and lacustrine facies can be divided into shore lacustrine subfacies and shallow lacustrine subfacies.The evolution of the sedimentary environment from bottom to top is delta plain-delta front-shallow lacustrine.It embodies the deepening process of the water body during the depositional period of Quan4 Member.The distributary channel microfacies of meandering-delta is the most developed,and the sandstone is favorable reservoir.Because the muddy rock of interdistributary microfacies often enwraps or overlays distributary channel sand,mouth bar,thin sand layer and so on,good storage-seal assemblage,which is favorable for the generation of lithologic trap hydrocarbon reservoir,is formed.
