Emergency petroleum bore hole closure arrangement for use in e.g. land, has explosive bodies spaced from each other, where hole is split by introduction of dips to form seal such that seal withstands pressure of petroleum applied on seal

摘要

The arrangement has multiple explosive bodies spaced from each other after ignition of the explosive bodies by an igniter cord or a radio remote ignition process. Multiple auxiliary holes (4) are formed on a petroleum bore hole (3) on a land or at sea (10). The petroleum bore hole is split by mass introduction of seal dips (15-17) in a region of the petroleum bore hole to form a seal such that the seal withstands pressure of petroleum applied on the seal.
