METHOD FOR SECONDARY SEAM OPENING

摘要

Method for secondary seam opening includes perforation of well and implosion effect on critical area of formation. Perforation is performed by cumulative perforator and implosion effect on critical area of formation is performed with delay through destruction of hermetic implosion chamber connected by detonating fuse to detonation chain of perforator. Delay of beginning of implosion effect is provided by preliminary choice of length L of detonating fuse that is preliminarily chosen from relation, where D – rate of detonation.
