Multi-zone single treatment gravel pack system

摘要

A gravel pack system includes a tool string having an inner string member, an outer string member, and a passage arranged between the outer string member and the inner string member. A packing element is provided on the outer string member. A first valve is coupled to one of the outer string member and the inner string member outwardly of the packing element in a downhole direction. The first valve fluidically connects the passage and the open hole wellbore. The first valve is configured and disposed to shift from a closed position to an open position. A second valve is coupled to one of the outer string member and the inner string member outwardly of the packing element in an uphole direction. The second valve selectively fluidically connects the passage and the open hole wellbore. The second valve shifts from an open position to a closed position.

1. A multi-zone single treatment gravel pack system comprising:
a tool string including an inner string member, an outer string member, and a passage arranged between the outer string member and the inner string member; at least one selectively deployable packing element provided on the outer string member; a first valve coupled to one of the outer string member and the inner string member outwardly of the at least one selectively deployable packing element in a downhole direction, the first valve selectively fluidically connecting the passage and an open hole wellbore, the first valve being configured and disposed to shift from a closed position to an open position; and a second valve coupled to one of the outer string member and the inner string member outwardly of the at least one selectively deployable packing element in an uphole direction, the second valve selectively fluidically connecting the passage and the open hole wellbore, the second valve being configured and disposed to shift from an open position to a closed position, wherein the open hole wellbore uphole of the at least one selectively deployable packing element is selectively fluidically connected with the open hole wellbore downhole of the selectively deployable packing element through the passage.
