摘要： A cover configured to dispose over a treatment port of a downhole treatment tool, the cover comprising a dissolvable material. A system for protecting treatment ports in a downhole treatment tool, the treatment tool having an outer surface and an inner bore, the inner bore in fluid communication with the outer surface through one or more treatment port orifices disposed on the outer surface of the treatment tool, and a dissolvable treatment port cover disposed in the fluid communication path of the treatment port. A method for treatment of a well including the steps of locating a treatment tool in a well, the treatment tool having a treatment port and a cover over the treatment port; setting an activation tool in the well; placing a treatment, applying pressure to rupture the cover; and unsetting the activation tool.

摘要： A down-hole treatment tool including a tool body having a bore therethrough, a treatment port orifice disposed on the body, a sliding sleeve within the bore of the body. A constant-volume annular chamber, in isolation from the inner bore and the environment outside the body, provides a debris-free environment for locking the sleeve. A dissolvable treatment port cover provides protection of the treatment port until operation of the treatment port is needed. The treatment port cover and lubrication ports enable lubrication of the sleeve and inner bore of the body without risk of contamination by debris.

摘要： A system for selectively treating zones in a cased well-bore, including a downhole tool, having a body, an inner bore, and an outer surface. The tool body has at least one treatment port disposed on the outer surface and a sliding sleeve disposed within the inner bore for selectively isolating the inner bore from the outer surface. The sliding sleeve can be positioned in a closed position or open position with respect to the treatment port. A collet disposed around an outer surface of the sliding sleeve is for maintaining the sliding sleeve in an open position. At least one finger on the collet engages the inner surface of the bore for maintaining the sleeve in an open position. The sliding sleeve also has a means for maintaining the inner sliding sleeve in a closed position.
