Abstract
A sand-capturing tool is disclosed, as well as a method. The tool relies on an eductor. The eductor is supplied by pumped fluid from the surface through a coiled tubing support for the tool. The eductor induces flow into a central tube in the tool which brings in with it the sand to be captured. Ultimately, the cross-sectional area of the induced fluid flow is increased to reduce its velocity and to further induce the sand which has been brought through the narrow inner tube to drop out into an annular area around the inner tube. The clean fluid exits through a screen and goes around the eductor and uphole to the surface. In an alternative embodiment, the assembly can be supported on an electric line employing a downhole pump which provides the motive fluid force for the eductor jet. In this embodiment, the remaining operation is the same.
