| 摘 要： | 由于地层水和油气保存之间关系密切,因此在油所勘察中对地层水的研究具有重大的实际意义。川西坳陷须家河组二和四段地层水的常量离子组成及其各种化学特性系数研究发现,地层水的主要离子Na+、Cl-显示出地层水随深度增加有正向浓缩作用,而Ca2+、Mg2+、SO42-等的变化则说明所受各种因素的影响。须二和须四段地层水的地化特征虽存在一定差距,但其地层水均具有正向浓缩、深变质的特点,显示油气保存条件好,具有极大地勘探潜力。

| Abstract: | Formation water is of great importance to preserve of oil and gas.Major ion compositions and chemical property of formation water in the 2nd and 4th Members of the Xujiahe Formation show that the formation water is characterized by content of Na+ and Cl-increases with the depth,suggesting good conditions of preserve of oil and gas. |
