摘　　要：本文概括地论述了在长庆马岭油田注水开发过程中注入的淡水与地层高矿化度盐水之间、与储层岩石之间的化学作用以及这些作用对产出水组成的影响。On the basis of a comprehensive scientific field investigation into inner reservoir scaling problems in Malin Oil Fields, Changqing, the chemical interactions between the imcompatible injected fresh water and high salinity formation waters in different oil bearing strata, the chemical reactions of the injected fresh water and the rock minerals in contact, and the resultant changes in chemical composition of the produced waters are described in this paper. The relations of various salts deposites to the chemical changes in the waters are analyzed and summarized.
