| 成果简介 | NOVELTY - Composition based on oil sludge for increasing oil recovery of formations includes, vol.%: viscous oil-containing product – oil sludge with viscosity of 180-350 mPa⋅s 60-80; dispersed filler – sodium type montmorillonite clay 5-10; aqueous solution of sodium hydroxide with density of 1.1 g/cm3 15-30. Oil sludge contains, wt.%: oil products from more than 50 to 75; mechanical impurities less than 20 and water 25-30. Volume ratio of said clay and aqueous sodium hydroxide solution is 1:3, respectively. USE - Oil industry. ADVANTAGE - Levelling profile of injectivity of injection wells, increasing strength and maintaining thermal stability of flow deflecting screen, improving viscosity and elastic properties and versatility of the used composition, maintaining stability of formed emulsion during pumping time and at provision of residual resistance factor after pumping of at least 10 units. 1 cl, 2 tbl, 1 ex |
