1. Description
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. The maximum output of these guns is 200000 meters a year, different size of perforating guns can be developed and produced according to customer requirements.
2. Specifications
2.1 Materials : 32CrMn4
2.2 Temperature Rating ：325℉
2.3 Pressure Rating ： 10150 Psi
2.4 Phasing：90° Left Rotation
2.5 Application Condition:
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.
