摘要

On the basis of calculation and analysis of 1 160 testing datum including salinity, formation water types, content of each ion such as Cl^-, Na⁺ , Ca²⁺ , Mg²⁺ , HCO₃^-, SO₄^2- , and physical property of crude oil such as density, viscosity, freezing point, paraffin content the formation water chemical field of the Paleogene system of Zhanhua sag was investigated. The results showed the obvious differences to the characteristics of the sealing and stagnating formation water chemical field of the Paleogene system of Dongying sag, the formation water chemical field of the Paleogene system of Zhanhua sag had typical characteristics of opening lacustrine faultedbasin. The macroscopic typical characteristics of formation water chemical fields in opening lacustrine faulted-basin not ruled out some sealing and stagnating formation water chemical fields in some areas such as Bonan subsag.
