Title (EN) HIGH PRESSURE JET PERFORATION SYSTEM
(FR) SYSTÈME DE PERFORATION PAR JET À HAUTE PRESSION
Abstract:
(EN) A technique facilitates removal of excess sand during a jet perforating operation without requiring that the perforating string be pulled out of hole. A jet perforating tool is provided with at least one perforating nozzle for creating perforations in a well via high- pressure fluid. The jet perforating tool also comprises at least one wash nozzle oriented to direct fluid under pressure against a sand plug to break loose excess sand. A pair of seats and plug members may be used in the jet perforating tool to control the flow of pressurized fluid through the perforating jet nozzle and/or the wash nozzle.
(FR) Selon l'invention, une technique facilite l'évacuation d'excès de sable pendant une opération de perforation par jet sans exiger que la tige de perforation ne soit extraite du forage. Un outil de perforation par jet comporte au moins une buse de perforation destinée à créer des perforations dans un puits au moyen d'un fluide sous haute pression. L'outil de perforation par jet comprend également au moins une buse de lavage orientée pour projeter un fluide sous pression contre un bouchon de sable afin de briser et fluidifier l'excès de sable. Une paire d'éléments de sièges et d'obturateurs peuvent être utilisés dans l'outil de perforation par jet pour commander l'écoulement de fluide mis sous pression par la buse à jet perforant et/ou la buse de lavage.
