| Abstract: | The technical difficulties in re-perforating horizontal holes or highly deviated holes are depths control, primary detonations and interlayer propagated blasts. Choosing the detonating method of pressure compound initiator or tailored sieve tube coordinating with pressure initiator, effective primary explosion and construction security may be guaranteed. Adoption of the matching structure with boost device and pressure initiator at the thick interlayer section can effectively guarantee the normal detonation... |
