Introduction of the perforating gun
Perforating gun is used to protect the detonators, perforating charges, carriers, detonating cord and other parts from
underground impact caused by high-pressure, acid and alkali, operating shocks and vibrations and other factors.
There are 40 types of perforating guns, mainly including 51 series, 60series, 73 series, 76 series, 89 series, 102
series, 114 series, 127 series, 140 series, 178 series and compound series.
It is applicable to low porosity, low permeability and low oil pressure well perforating operation, usually in the
circumstances of large negative pressure. It is used in the formation that is seriously polluted and need to be
restructured by using the nature of deep penetration to change the formation and better the yield. The overlying fluid
pressure is not less than 145 Psi.
