Exposed through tubing perforating charge is developed in accordance with the demand of through tubing perforating or reperforating in the process of oil field production. It combines such technologies as self-sealing and flexible connection structure together, featuring small diameter and smooth through tubing. It can perforate the whole well in one downhole run and achieve good effects both in operating efficiency improving and cost saving.
It can be divided into 2 series, O.D.- 2.48〞serial and O.D. -2.13〞serial at the shot density of 4～6 spf. Both of them can be used in 2-7/8″ tubing perforating operation under the pressure of 15,225 Psi.
