FLUID FOR TREATMENT OF PRODUCTIVE FORMATION AND UNDERGROUND EQUIPMENT OF BOREHOLES

摘要

The invention relates to gas and oil producing industry, in particular to well treatment with surfactants. A fluid for treatment of productive formation and underground equipment of borehole contains, wt. %: butamyl dissolvent 5-50, nonionic surfactant 0.05-5, hydrocarbon solvent the rest. Provided are improvement of oil-driving properties of solution in oil-filled formations characterized by asphalt-resin-paraffin deposits (ARPDs), resolution of these deposits, retrieving the input parameters of in-place permeability.
