Description
Technical field
The utility model relates to perforating system used in oilfield well completion field, particularly perforating system is held in a kind of non-explosive expansion.
Background technology
Perforating system is the special equipment during oil field development is produced, and after completing, carries out perforation to the borehole wall for oil drilling.What commonly use in oil field is conventional jet perforating rifle, although this rifle greatly increases perforation efficiency, but the high temperature of lined-cavity charge, high pressure can extrude and form compaction band around duct, cause perforation and pollute, the serious permeance property that have impact on wellbore stratum.How in perforating process, to remove formation contaminant, improve perforation degree of perfection, increase Oil & Gas Productivity and become a problem demanding prompt solution.
Summary of the invention
Serious for formation contaminant in perforating process, Oil & Gas Productivity is low, and the utility model provides a kind of non-explosive expansion and holds perforating system.
The technical scheme in the invention for solving the technical problem is: this non-explosive expansion is held perforating system and is made up of positioning disk, subordinate's firing mount, subordinate's perforating gun body of a gun on positioning disk, tension dish, perforating gun list joint, upper detonating primer, energizer centralizer body, lower detonating primer, shop bolt, lower detonating fuse, upper detonating fuse, upper detonating fuse centralizer body, pressing pin, energizer, sealing ring, lower detonating fuse centralizer body, firing mount under higher level's perforating gun body of a gun, higher level's firing mount, firing mount; Higher level's perforating gun body of a gun, subordinate's perforating gun body of a gun respectively with the screwed connection of perforating gun list joint, perforating gun list joint has centre bore, perforating gun list upper end of joint connects higher level's firing mount by positioning disk under firing mount, and perforating gun list joint lower end connects subordinate's firing mount by positioning disk on firing mount; The lower end of upper detonating fuse centralizer body is inserted in the centre bore on perforating gun list joint top, positioning disk screwed connection under upper end and firing mount, between positioning disk, tension dish is housed under upper detonating fuse centralizer body and firing mount; The upper end of lower detonating fuse centralizer body is inserted in the centre bore of perforating gun list joint bottom, and lower end and positioning disk screwed connection on firing mount, be equipped with the energizer being with energizer centralizer body between upper detonating primer and lower detonating primer.
Adopt the good effect of technique scheme: relieve formation contaminant serious problems, improve perforation degree of perfection, add Oil & Gas Productivity.
