摘要： A shaped charge includes a main body of explosive and a primer adapted to detonate said main body of explosive. In accordance with the present invention, the main body of explosive now includes an explosive composition known as sym-triaminotrinitrobenzene (TATB) and, since TATB is not sensitive enough to be a primer, the primer must consist of an explosive composition which is more sensitive than TATB. It has been discovered that, when the main body of explosive in a shaped charge is modified to include the explosive composition known as TATB and when the primer includes an explosive other than TATB, such as HNS or NONA or PYX or HMX, or a mixture of HNS or NONA or DODECA or PYX or HMX and TATB and when the shaped charge is detonated, the detonated charge will produce a jet that is longer in length than the jet associated with prior art shaped charges which did not have a main body of explosive that included TATB. As a result, when the longer jet is produced from the shaped charge of the present invention, that has been modified to include a main body of explosive comprising TATB and a primer which is more sensitive than said TATB, the longer jet will produce a longer perforation in a formation penetrated by a wellbore and, as a result, an increased quantity of wellbore fluid will be produced from the perforated formation. A detonating cord could also include the TATB explosive.
