Secondary opening of productive layers by mechanical devices

Abstract

When using mechanical perforators, the destruction of the cement ring is excluded and, accordingly, the tightness of the sealed space is preserved, rock compaction and contamination of the walls of the perforation channels with explosion products is excluded. The productivity of the well increases, up to a multiple, and the ecological cleanliness of the perforation process is ensured. The most preferred use of mechanical perforation in the development of low-power oil-saturated intervals, which for one reason or another were not used at the initial stage of field exploitation.
