摘要 A well tool adapted to be connected with and disconnected from a well tubing using a power tong device having a pair of tongs, a gripping span between the pair of tongs, and a maximum clearance diameter for an object passing through the tongs. The well tool includes a tubular mandrel. The tubular mandrel has a maximum mandrel diameter which is no greater than the maximum clearance diameter. The tubular mandrel includes a first mandrel connector which is adapted for connecting the tubular mandrel with a first well tubing in order to provide a first connection. The tubular mandrel is configured so that when the power tong device grips a tong gripping surface on the tubular mandrel and the first well tubing in order to connect the tubular mandrel and the first well tubing, the first connection is located within the gripping span.
