초록 ▼

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.

대표청구항 ▼

[ What is claimed is:] [1.] An apparatus for capturing downhole contaminants through tubing in a well, comprising:an elongated body defining a chamber therein;at least one tubing segment releasably attached to said body without threading:said tubing segment having an open lower end adjacent from which an open ended tubular inlet tube extends longitudinally toward said chamber and defines an annular retention compartment around itself, said compartment extending to adjacent said lower end of said tubing segment;said compartment extendable without threading by an additional tubing segment having therein its own tubular inlet tube which connects without threading to said tubular inlet tube already supported from said tubing segment;a pressure-reduction device acting on said chamber to draw fluid laden with contaminants through said inlet tube and into said chamber for deposit of the contaminants in said retention compartment.
