A quick connection for coiled tubing run tools eases the assembly and disassembly while deploying such tools. The quick connection utilizes a locking collet and an inner mandrel with locking sleeve system. Such a quick connection does not require perfect alignment between mating pieces.

Coiled tubing connector for downhole tools

A switch includes a casing having a bore, a piston assembly having a first end and an exposed end, a plurality of flanges formed at the first end; an insulating sleeve enclosing the first end, a contact assembly disposed in the casing bore; a pin disposed in the bore; a predetermined quantity of lubricant deposited in the bore; and a spring urging the pin into engagement with the piston assembly. The insulating sleeve and the plurality of flanges are at least partially disposed in the casing bore. The pin has: (i) a first position wherein the pin electrically contacts the piston assembly and is electrically isolated from the contact assembly; and (ii) a second position wherein the pin is electrically isolated from the piston assembly and electrically engages the contact assembly. The predetermined quantity of lubricant may be approximately 0.3 grams.

Pressure switch for selective firing of perforating guns

An apparatus for selectively isolating a firing head associated with a perforating gun may include an igniter coupled to a firing head, a time delay module coupled to the igniter and generating a pressure pulse after being activated by the igniter, a metering module, and a second firing head. The metering module may be coupled to the time delay module and including a housing having a bore and at least one opening exposed to a wellbore annulus. A piston disposed in the housing bore may have at least one passage. The piston is axially displaced from a first position to a second position by the generated pressure pulse. The second firing head is coupled to the metering module and is in fluid communication with the housing bore. The piston blocks fluid communication from the at least one opening of the housing and the second firing head in a first position and allows fluid communication from the at least one opening of the housing to the second firing head in the second position.

Firing mechanism with time delay and metering system

An apparatus for detonating an explosive body associated with a downhole tool includes a plurality of firing heads, each firing head including an initiating explosive body generating a high-order input when detonated; and a funnel configured to detonate the explosive body associated with the downhole tool by using a single high-order output. The funnel has a body that includes: a plurality of input openings, each input opening positioned next to an associated initiating explosive body to receive the generated high-order input, a single output opening, and a flow path connecting the plurality of input openings with the single output opening.

Redundant firing system for wellbore tools

An interrupter for use with a wellbore tool may include a housing having an interior and a fusible body disposed in the housing interior. The fusible body may be solid below a specified temperature and liquid above the specified temperature. The fusible body communicates a first high-order detonation to a detonator only when liquid. The communicated the first high-order detonation is at a magnitude sufficient to cause the detonator to produce a second high-order detonation.

Detonator interrupter for well tools

A well isolation includes a radially expandable sealing element that engages an interior wall of the wellbore tubular and a radially expandable expansion cone in telescopic relationship with the sealing element. The expansion cone expands the sealing element and a swage telescopically engages and expands the expansion cone.
