SPD2 device is applied for the liner and transport string self-priming in the process of running into a well and receiving the “bump” signal while performing direct cementing during
which the hollow cementing plug, as a part of PHCZ or PHGMC liner hanger, together with
the upper cementing PCV plug is set into the device seat.
Besides, the device can be applied for actuation of PHRC hanger anchor unit while RIH of
a liner with continuous cementing using PHRC hanger.
