Abstract: The experimental fish species(carp fry)recommended by the Organi-zation for Economic Cooperation and Development were adopted to carry on acute toxici-ty test with three kinds of driIling fluid: waste,polymer system and 3-K polymer. TheLC,,values, concentration values and the concentration value range of 95% confidencelevel of these three kinds of fluid had been calcuIated by probability single-value regres-sion method. The classification standard of American bran-shrimp test method had beenadopted to evaluate drilling fluid toxicity,and the toxicity of main chemical additives indrilling fIuid had been analyzed. The resuIt showed that the toxicity concentrations ofthose three kinds of dri1ling f1uid in Daqing oil field were all ranged within nonpoisonousscope.
