Sun Qing · Special Oil & Gas Reservoirs · 2003
Perforation detection in Liaohe oilfield is limited to visual inspection of perforating gun on the surface, and there is no way to verify downhole perforation. For this situation, perforation quality detecting instrument has been developed. This instrument can quantitatively measure the location and amount of perforation, thus providing basis for reperforation.
