PROCESSING METHOD OF BOTTOM-HOLE FORMATION ZONE WITH CHARGE AT INCREASED TEMPERATURES

摘要

FIELD: oil and gas industry.;SUBSTANCE: method involves creation of excess pressure in a well by action on a formation with gaseous combustion products of propellant charge. According to the method, at prolonged high-temperature action on propellant charge at its lowering into the well, propellant charge is used together with a stiff combustible cap that contains the following components, wt %: thermoreactive polymer composition - 30…37; pyroxiline fibre - 18…22; explosive component - 42…48 and over 100%: ethyl alcohol - 10; wetting agent - 0.1.;EFFECT: increasing safety of a processing method of bottom-hole formation zone and its efficiency owing to reducing deformation of propellant charge.;1 ex, 1 dwg
