摘要：

建立了1种离子色谱抑制电导法测定气井实钻过程中钻井液中Cl^-、SO^2-₄、Ca^2+、Na⁺⁴种关键离子质量浓度的方法。通过分析4种离子质量浓度在不同井深的变化规律,初步建立起四川盆地海相地层及流体识别解释标准,可以准确识别碳酸盐岩地层所含流体性质,判断是否钻遇气层或水层,还能通过所识别出的地层水类型来推断地下构造开放程度,确定气藏的保存条件。该方法灵敏度高、准确度好,有效丰富了地质勘探的检测手段,为四川盆地天然气钻探提供科学的依据。

Abstract:

A new method of suppressed conductivity ion chromatography for determination of four kinds of ions Cl^-, SO²-_4, Ca^2+, Na+ was developed. By analyzing the mass concentration variation of four ions, the fluid identification interpretation criteria of Sichuan Basin marine strata was established, which could accurately identify the fluid properties in carbonate formation and judge whether a gas layer or a water layer to be drilled. This criteria could also deduce the opening degree of underground structure by identifying the formation water type to determine the storage conditions of gas reservoir. The results showed that this method had high sensitivity and good accuracy, which could enrich the detection methods of geological exploration and could also provide scientific basis for Sichuan Basin gas drilling.
