Abstract

Et fluidinjeksjonsapparat og fremgangsmåte sørger for en styrt volumfortrengning for bruk av apparatet i en underjordisk brønn. Trykket er påført innen en ledning som fører apparatet inn i brønnen for aktivering av et stempel og sammentrekking av et kammer som inneholder et behandlingsfluid for utstøting av behandlingsfluid inn i brønnen. Et flertall av kammere kan være isolert ved stempelinnretningen i forhold til ledningspassasjen for selektiv, inkremental utstøting av fluidet og be- handling av en eller flere soner eller seksjoner innen brønnen.A fluid injection apparatus and method provides a controlled volume displacement for use of the apparatus in an underground well. The pressure is applied within a conduit which enters the apparatus into the well for actuating a piston and contraction of a chamber containing a treatment fluid for ejecting treatment fluid into the well. A plurality of chambers may be insulated by the piston device relative to the conduit passage for selective, incremental ejection of the fluid and treatment of one or more zones or sections within the well.
