摘要： 对80 年代末以来发表的乙酸与金属元素配合物稳定常数值进行了调研, 发现与SOLMINEQ.88软件数据库相差甚大, 进而加以修改, 并模拟计算了塔里木盆地高矿化度油田水金属-有机酸配合物的存在形式及其含量。结果表明, 16 %~ 69 %的乙酸可以Ca 、Na 、Mg 、Sr 、Al 、K 、Fe 的配合物存在,AlAc2 +可占总Al 的19 %~ 94 %,其含量变化与pH 值紧密相关。

Abstract: This paper analyzed the stable constant value of acetic acid and metal element complex compound published since late 1980's, discovered that big difference appeared between these data and those from SOLMINEQ.88 software data base, hence modified this data base, and simulated the form of metal-organic acid complex compound with high salinity oilfield water and calculated its content in Tarim basin.The results showed that acetic acid of 16% to 69% occurred in form of Ca, Na, Mg, Sr, Al, K, Fe complex compound, AlAc2 + accounted for 19% to 94 % of total aluminum quantity.And there is a close relation between AlAc2 + content and pH value.
