摘要
地层水(油气田水)是与油气共存的地下水,它与油气的生成、运移、聚集和成藏有着重要联系。本文通过对苏里格气田石盒子组地层水总矿化度、变质系数、脱硫系数、碳酸盐平衡系数、镁钙系数和氯镁系数等化学特性参数的实验分析表明,除苏20井及其附近地区外,苏里格气田大部分地区石盒子组地层水封闭条件较好,处于停滞状态,有利于油气聚集和保存,尤以苏里格南部地区为最好。
Formation water(field water)is a kind of groud water that coexsits with oil and gas,it has important relations with the generation,migration,accumulation and preservation of oil and gas.This paper focuses on the total dissolved solids(TDS),Deterioration factor(rNa+/rCl-),Desulfuration factor(100(rSO42-/rCl-),Carbonate balancing factor(rHCO3-+rCO32-/rCa2+),Ratio of magnesium to calcium(rMg2+/rCa2+) and Ratio of chlorine to magnesium of formation water from Shihezi Formation in Sulige Gasfield,According to the analysis results of these chemical characteristics,except for Well Su20 and its adjacent area,most formations show favourable sealing conditions and formation waters are in a state of logjam.So most areas of Sulige Gasfield,especially in the south,are in favor of accumulation and preservation of oil and gas.
