Claim:
A tool string comprising a plurality of interconnected tools for deployment in an oil or gas well and through which fluids are passed to conduct well operations, wherein the plurality of interconnected tools comprises: an abrasive perforator; a second tool that is fluid-operated and that is below the perforator in the tool string; wherein the abrasive perforator comprises: an upper end having an inlet; a lower end having an outlet; a tool body extending between the upper and lower end of the tool and defining a fluid flow channel therebetween; wherein the tool body comprises at least one transversely directed jet nozzle continuous with the flow channel; a sleeve disposed within the flow channel in the tool body; and wherein the sleeve and the flow channel in the tool body are configured to allow sliding movement of the sleeve from a first non-perforating position that permits pressurized fluid flow through the perforating tool to operate the second tool and a second perforating position that permits the fluid flow to produce a perforating fluid stream through the at least one jet nozzle.
