ABSTRACT:
In an oilfield wireline tool string, a self-contained downhole power unit is positioned at a designated working location and mechanical jars cut shear pins retaining an activating mandrel so as to displace a valve seat and open a mechanically actuated valve. This valve admits well pressure to a pressure-sensing switch in the downhole power unit to initiate its operation.
