Formation fracturing and gravel packing tool

摘要

Apparatus (40) for use with an item of equipment (10a) operatively positionable within a subterranean well. The item of equipment (10a) includes a slurry delivery flow passage (32a) and an internal fluid return flow passage (34a) for returning a fluid portion of a slurry to the earth's surface. The apparatus (40) comprises: a primary fluid port (52) interconnectable in series with the fluid return flow passage (34a), the slurry fluid portion flowing through the primary fluid port (52) when the fluid portion is returned to the earth's surface; and a restrictor (58) disposed adjacent the primary fluid port (52), the restrictor (58) being selectively displaceable relative to the primary fluid port (52) to thereby variably restrict flow of the slurry fluid portion through the primary fluid port (52).
