摘要

Neogene formation water and its response to hydrocarbon distribution in Liuxi-Liubei Area, in which hydrocarbon was richest in Raoyang Sag of Jizhong Depression, were analyzed. The  distribution characteristics of salinity and hydrochemical type of Neogene formation water were discussed. The internal relationship between abnormal geochemistry characteristics of Neogene formation water and the migration and distribution of hydrocarbon in the area was revealed. The results showed that Neogene developed NaHCO₃ type of formation water with low salinity in Liuxi-Liubei Area. The corresponding relationship between abnormal Neogene formation water and hydrocarbon distribution was fine under the condition of good oil source and fault.
