Abstract

L'invention porte sur un bourrage de gravier d'un forage de puits, lequel bourrage peut mettre en œuvre le transport simultané de trains de tiges de production et de distribution de boue de gravier séparés dans le forage de puits, l'écoulement d'une boue de gravier à travers le train de tiges de distribution de boue de gravier et dans un anneau autour du train de tiges de production, et la production de fluide à partir du forage de puits par l'intermédiaire du train de tiges de production. L'invention porte également sur un système de bourrage de gravier, lequel système peut comprendre les trains de tiges de production et de distribution de boue de gravier positionnés latéralement au voisinage l'un de l'autre dans un forage de puits, le train de tiges de distribution de boue de gravier étant en communication vis-à-vis des fluides directe avec un passage dans un dispositif de bourrage, et le train de tiges de production étant en communication vis-à-vis des fluides directe avec un autre passage dans le dispositif de bourrage. Un autre procédé de bourrage de gravier peut mettre en œuvre l'écoulement de boue de gravier à travers un train de tiges de distribution de boue de gravier et dans un anneau autour d'un train de tiges de production, la production d'un fluide à partir du forage de puits par l'intermédiaire du train de tiges de production, ces étapes étant effectuées sans manipulation de l'un ou l'autre des trains de tiges dans le forage de puits.
