METHOD OF REAGENT FOR DRILLING MUD PRODUCTION

摘要

FIELD: drilling of oil and gas wells, production of reagents for drilling mud in particular. SUBSTANCE: aim is to decrease consumption index of reducer with preservation of high operational and technical properties of drilling mud reagent. Method provides for thermal alkaline sulfitization of dried in "boiling layer" and humid slime lignins taken in mass % ratio of 1 : (1.5 -2). In the case alkali and sodium sulfate are taken in amount of(0.2 - 0.3) and (0.1 - 0.2) mass shares correspondingly to one mass share of dry slime lignin. EFFECT: decreased consumption index of reducer with preserved high operational and technical properties of drilling reagent.
