WELL TOOL WITH INDEXING DEVICE

摘要

A well tool can include an operator device with an operator profile and at least two routes, and an indexing device with a cam and a cam follower including a structure. The structure engages the routes in succession in response to relative displacement between the operator profile and cam. A method can include causing relative displacement between an operator device and an indexing device in one direction, thereby causing a structure to disengage from one route of the operator device and displace an initial distance between two routes in response to engagement between the cam follower and a cam, and causing relative displacement between the operator and indexing devices in an opposite direction, thereby causing the structure to displace a remaining distance between the routes in response to engagement between the cam follower and an operator profile of the operator device, and to displace along the second route.

1. A well tool, comprising:
an operator device including an operator profile and at least two routes; an indexing device including a cam and a cam follower, the cam follower including a structure displaceable along each of the routes; and wherein the structure engages the routes in succession in response to relative displacement between the operator profile and the cam.
