FIELD: chemistry.SUBSTANCE: invention relates to drilling mud emulsifiers. Disclosed is a polyamide compound of formula (A), where a is an integer from 1 to 5, b and c are each independently selected from integers from 0 to 10, under the condition that b and c are not equal to 0 at the same time, d is an integer from 0 to 10, e is an integer from 1 to 5, Y is selected from H, X, -C(O)Ror -C(O)Rand Z is selected from -C(O)Ror X, where Rand Rare linear or branched, saturated or unsaturated hydrocarbyl groups having 7 to 30 carbon atoms, and X is a carbonyl group obtained from a carboxylic acid. The invention also discloses a method of producing said compound, use thereof as an emulsifier in drilling mud and the respective drilling mud composition.EFFECT: disclosed compound is an effective emulsifier at high temperature and pressure, which reduces the required amount of the emulsifier and the cost of the system; Y{O(CH)}{NX(CH)}{N[C(O)R](CH)}{NH(CH)}NHZ (A).15 cl, 2 dwg, 6 tbl, 11 ex |
