FIELD: petroleum industry.
SUBSTANCE: invention refers to the well-drilling. Polymer peat alkaline drilling mud for drilling in production shelves of oil and gas wells during the drilling process contains, %: peat - 5-8; potassium-containing alkaline modifier - 0,5-1,5; foam suppressant MAC-200M - 1-3; Barite loading material - 10-40; lubricant - sapropel - 1-10; fluid loss reducing agent and flocculant - polymer DK DRILL - 0,3-1,4; water - the rest.
EFFECT: revelation of production horizons during the drilling process with preservation of permeability and porosity properties of reservoirs rocks.
