| 摘 要： | 根据化学分析原理，提出了用试油排液中某些离子含量的变化趋势来计算池液侵入量的方法。通过对比分析钻井液等流体化学成分与试油排液化学成分，确定污染地层的主要来源。以胜利油田具有代表性的埕北１２—１井为实例，计算出该并滤液侵入量，认为污染不严重，污染来源为钻井液，固井液等的污染可视为零。

| Abstract: | According to chemical analysis principle, the article puts forword a way to determine invasion filtrate volume through analysing change tendencies of some ions'contents in oil produced during well testing.Fluid which contanimated formations is determined by making contrasts between chemical components of drilling fluid,etc.and those in oil produced during well testing.A field application case is presented. |
