In order to reduce the word errors，several groups of easily confusing terms commonly used in daily editing were analyzed，including“配制（preparation）”and“配置（configuration）”，“瓜尔胶（guar gum）”and“胍胶（guanidine gum）”，“黏度 （viscosity）”and“粘度（viscosity）”，three structural auxiliary words，and“氨（ammonia）”，“胺（amine）”and“铵（ammonium）”. By analyzing the interpretation of preparation and configuration，“preparation”should be used when involving the preparation of solution in periodical.“Guar gum”was a standard technical term，so“guanidine gum”should not be used in oil and gas industry. “Viscosity”was a physical property of a fluid，so it should be written as“黏度”. Three structural auxiliary words，such as“的”， “地”，“得”，should be distinguished，which made written language accurate. By analyzing the definition，structure and properties of ammonia，amine and ammonium，as well as the common examples of chemical reagent names in the field of oilfield chemistry， this paper provided reference for the correct and standardized use of scientific and technical workers and periodical editors.
