The characteristics of formation water and formation water resistivity in Cha 48 block Gaotaizi reservoir

摘要

The analysis of formation water in oil field exploration development is the process of critical test parameters.The total salinity of formation water is an important indicator in the water analysis data.This paper discusses formation water physical properties,chemical composition,main ion combination characteristic in cha 48 block of south changling sag.We analysis the types of formation water,water distribution,chemical composition characteristics on the lateral variation,the changing rules of the formation water resistivity.Improving the oil and water layer logging interpretation accuracy and discovering potential low resistance oil layer are very important in raise production on oil field.
