摘要(Abstract)：

兴隆台潜山太古界地层水中Cl~-的含量较高,变质系数为0.94~1.14,脱硫酸系数为1.8%~5.6%。平面上,边界断层(台安大洼断层)附近水的交替作用较活跃,地层水变质系数高,1 800~2 100 m的HCO_3~-含量由凹陷边缘向中心递增,低值主要分布在边界断层附近;剖面上,太古界地层水中Cl~-含量高于东营组和沙河街组,地层水的变质程度低,处于封闭环境,油气保存条件好。基于兴隆台潜山内幕油藏存在多套油水系统推测:潜山内幕地层水为"夹层水",潜山内幕深层依然具备成藏条件。
Cl~-content in Archean Erathem formation water is of Xing longtai buried hill relatively higher,the metamorphism factor of the water of Xinglongtai buride hill is 0.94-1.14,the desulfation factor is 1.8%-5.6%.On horizon,the water exchange is more active near the boundary faults(Tai'an and Dawa Fault) and metamorphism factor is pretty higher.The content of HCO_3~-(1800-2100 m)progressively increases from the margins to the center of the sag,the lower values are mainly distributed nearby the marginal faults,the profile analyzes thta the content of Cl~- in the water is higher than that in Dongying and Shahejie Formations,the metamorphism degree of the water is pretty lower.The water is located in enclosed environment and the hydrocarbon is well reserved.It developed in enclosed environment and with well reserved hydrocarbons.According to the prediction by several sets of oil-water systems of oil reservoirs within the inner buried hill in Xinglongtai,the inner formation water is supposed to be "interbedded water",and the deep zones of the hill also have favorable conditions for petroleum accumulation.
