  This invention provides drilling fluid additives composed of copolymers which are obtainable by an industrially favorable process and superior in heat-resisting property. Furthermore, even though the additives are used in a relatively small amount, those sufficiently prevent change in properties of drilling fluid due to various kinds of hard water components being contained in underground water or cement as well as due to sea water, and the additives are able to display the properties of drilling fluid constantly regardless of presence or absence of salts. Drilling fluid additives of the present invention are composed of water-soluble copolymer ( A ) having average molecular weight of 1,000 - 50,000, which are led from monomer components composed of a monomer ( I ) of 40 - 99.5 molar percentages in a series of unsaturated carboxylic acids, as shown in the following general formula ( I ), and an unsaturated monomer ( II ) of 0.5 - 60 molar percentages in a series of ( meth )allylethers, as shown in the general formula ( II ). In the formula ( I ), each of A1 and A2 independently represents hydrogen, methyl, or -COOX2, and A1 and A2 are not -COOX2 at the same time. A3 represents hydrogen, methyl, or -CH2COOX3 and, in a case that A3 is -CH2COOX3, each of A1 and A2 independently represents hydrogen or methyl. Each of X1, X2, and X3, independently or at the same time represents hydrogen, monovalent metal, divalent metal, ammonium, or organic amine. In the formula ( II ) R1 represents hydrogen or methyl , and Z represents hydroxyl; a sulfonic acid group or its monovalent metal salt, divalent metal salt, ammonium salt, and organic amine salt; a phosphoric ( or phosphorous ) acid group or its monovalent metal salt, divalent metal salt, ammonium salt, and organic amine salt.
