Apparatus and method for use in subsurface oil and gas well perforating device
Patent
·
OSTI ID:6632245
An apparatus is described for perforating subsurface earth formations traversed by a borehole including a plurality of mechanically serially connected perforating guns, comprising: a first perforating gun member, the gun member including an elongated gun body having shaped charges cooperatively arranged thereon and a first length of detonator cord, for transferring an explosive wave to the shaped charges, traversing therethrough; a second perforating gun member mechanically serially connected to the first perforating gun member, the gun member including an elongated gun body having shaped charges cooperatively arranged thereon and a second length of detonator cord, for transferring and explosive wave to the shaped charges, traversing therethrough; and propagation means disposed within the first perforating gun member for eliminating any excess length of the first detonator cord from within the first perforating gun member and for propagating a detonating wave from the first detonator cord to the second detonator cord in the second perforating gun member.
