Apparatus and method for supplying fluid into different zones in a formation

摘要: There is discussed an apparatus for distributing fluid to at least two separate zones having higher (22) and lower (24) injectivity in a ground formation (10) through pipe element well hole (12), where the by means of upper sealing bodies (28,30) defines space (30) which adjacent zone has connection (16) zone, established between interior via replaceable flow pressure-regulating nozzle establishes given pressure current into injectivity. The characterized that comprises outer section (40) arranged internally relative latter inner (42) portion (54) closing off passage fluid, (32) forms (66) conveying forward injectivity, (58) (42), downstream (58), designed with (68) form annular (32).
