摘要
台北凹陷西部雁木西—神泉地区自下第三系始新统至渐-中新统桃树园组沉积期发育了近千米厚的膏盐岩,主要成分是硬石膏。本文从分析膏盐岩的沉积特征出发,结合成藏条件综合分析,指出膏盐岩对浅层油气的运移、聚集和保存起着至关重要的作用,膏盐层十分发育的胜南及雁木西油田周边是浅层继续滚动勘探的有利地区,应该值得重视。
During the sediment period from pre-Tertiary Eocene to Oligocene-Mioce neTaoshuyuan group developed almost one-thousand-meter-thick plaster salt rock,Whose most component is auhydrite,in the Yanmuxi-Shenquan region of the west of Taibei depression.Synthetical analysis on the sediment characteristics of piaster salt rock combining the condition of forming formation shows that plaster salt rock is vital to the migration accumulation and conservation of hydrocarbon in the low formation.The circumference of Shengnan and Yanmuxi Oil Field where plaster salt rock is greatly developed is of advantage for continuously rolling exploration in the low formation,which should be much thought of.
