Abstract

Perforeringsstrukturer (18) som tillater økt produksjon av fluider fra en brønn (10). Perforeringsstrukturene leder strømningen av fluider inn i brønnen i en retning med en komponent parallelt med aksen til brønnen og/eller med en komponent som ikke passerer gjennom midtaksen (22) til brønnen. Perforeringer i en produktiv sone kan skrånes nedover i forhold til midtaksen til brønnen. Perforeringer kan avbøyes tangentielt bort fra midtaksen til brønnen, slik at fluider som strømmer fra perforeringen har en retning i noen grad tangentielt med brønnforingsrøret og sirkulær bevegelse utvikles i fluider i brønnen. Fluider som passerer gjennom slike perforeringer opplever mindre trykkfall ved perforeringene, noe som øker trykket i brønnen og gir mer energi for å strømme fluider opp brønnen.Perforation structures (18) that allow increased production of fluids from a well (10). The perforation structures direct the flow of fluids into the well in a direction with a component parallel to the axis of the well and / or with a component that does not pass through the central axis (22) of the well. Perforations in a productive zone can be sloping downwards relative to the central axis of the well. Perforations can be deflected tangentially away from the central axis of the well, so that fluids flowing from the perforation have a direction somewhat tangential to the well casing and circular motion develops in fluids in the well. Fluids that pass through such perforations experience less pressure drop at the perforations, which increases the pressure in the well and provides more energy to flow fluids up the well.
