摘要
油气田地层水在物理和化学性质上都是十分活跃的物体,它与油气伴存,不仅可以改变油气性质,自身也在不断变化。变质系数、脱硫系数、碳酸盐平衡系数、镁钙系数和钠钙系数等常用的地层水化学特征参数,是判断气藏保存条件的重要参数。文章以此几类参数对呼图壁、霍尔果斯油气田的气藏保存条件进行了分析判断。
Formation water in oil-gas fields is an active substance in terms of physical and chemical properties.Accompanied with oil and gas,it can not only modify the properties of oil and gas,but also constantly change itself.Some common-used chemical characteristic parameters of formation water,including metamorphic coefficient,desulfurization coefficient,carbonate equilibrium coefficient,Ca/Mg ratio,and Na/Ca ratio are the key parameters for judging gas reservoir preservation.In this paper,the reservoir preservation in Hutubi and Huo′erguosi oil-gas fields has been analyzed and judged by these parameters.
