Title (EN) PULSED DELIVERY OF CONCENTRATED PROPPANT STIMULATION FLUID
(FR) DISTRIBUTION PULSÉE DE FLUIDE DE STIMULATION DE SOUTÈNEMENT CONCENTRÉ
Abstract:
(EN) One or more wellbore servicing operations may require the pulsed delivery of a wellbore servicing fluid. To optimize efficiency and effectives of a given wellbore servicing operation a concentrated proppant stimulation fluid may be pumped downhole at a predetermined time interval from dedicated pumping units or positive displacement pumps. The flow rate of proppant in the concentrated proppant stimulation fluid pumped from these dedicated pumps may simulate a square-wave. The desired or determined square-wave or output may be predetermined and any one or more dedicated pumps may be associated with a given time interval and pumping cycle or phasing such that the overall flow of proppant from all of the dedicated pumps simulates a square-wave. Clean fluid from one or more clean fluid pumps may be combined with the concentrated proppant stimulation fluid to maintain a target flow rate of fluid downhole.
(FR) Selon l'invention, une ou plusieurs opérations d'entretien de puits de forage peuvent nécessiter la distribution pulsée d'un fluide d'entretien de puits de forage. Pour optimiser le rendement et l'efficacité d'une opération donnée d'entretien de puits de forage, un fluide de stimulation de soutènement concentré peut être pompé en fond de trou à un intervalle de temps prédéterminé à partir d'unités de pompage ou de pompes volumétriques réservées. Le débit d'agent de soutènement dans le fluide de stimulation de soutènement concentré pompé à partir de ces pompes réservées peut simuler une onde carrée. L'onde carrée ou la sortie souhaitée ou déterminée peut être prédéterminée et une ou plusieurs pompes réservées peuvent être associées à un intervalle de temps donné et à un cycle ou un phasage de pompage tels que le débit global d'agent de soutènement à partir de toutes les pompes réservées simule une onde carrée. Du fluide propre provenant d'une ou de plusieurs pompes à fluide propre peut être combiné avec le fluide de stimulation de soutènement concentré pour maintenir un débit cible de fluide en fond de trou.
