发明名称 System and method for downhole communication
摘要 A method of servicing a wellbore extending from a surface and penetrating a subterranean formation is provided. The method comprises placing an assembly in the wellbore, wherein the assembly comprises at least a first downhole tool, a signal receiver subassembly, and a conveyance between the first downhole tool and the surface. The method further comprises the signal receiver subassembly receiving a first signal generated by contact between the wellbore and the assembly and initiating a first function of the first downhole tool based on the first signal.

主权项 1. A method of communicating within a wellbore extending from a surface and penetrating a subterranean formation, comprising: placing an assembly in the wellbore, wherein the assembly comprises at least one downhole tool, a trigger unit subassembly, and a conveyance between the downhole tool and the surface; axially manipulating the assembly at the surface to induce axial motion of the assembly in the wellbore to encode a discrete signal; analyzing an axial speed of the assembly in the wellbore as the axial speed changes over time to decode the discrete signal encoded by the motion of the assembly in the wellbore; and when the discrete signal matches a preprogrammed number, triggering a function of the downhole tool by the trigger unit subassembly.
