发明名称 TREATMENT METHOD OF BOTTOM-HOLE FORMATION ZONE
摘要 FIELD: oil and gas industry.SUBSTANCE: in the method for treatment of bottom-hole formation zone space above and below the perforation interval is straddled, solvent for asphalt, resin and paraffin deposits (ARPD) is injected into the straddled space, acidic agent - aqueous solution of acid - and displacing fluid is injected with maximum flow rate at pressure not more than 5 MPa, the process is withhold so that components could react and well is developed by swabbing. A mix of solvents MIS-prom, ITPS-RS and process water are used as ARPD solvent with the component ration of (0.34-0.38):(0.03-0.05):(0.57-0.63), polyamide acid salts are used as acidic reagent and oil is displacing fluid.EFFECT: increase of formation bottom-hole zone treatment efficiency.3 ex
