摘要： An isolation sub for use in a perforating system that includes a pressure activated firing head. The isolation sub is set between the pressure source that is used to initiate the firing head. A pressure regulator in the sub is responsive to fluctuations in pressure difference between the pressure source and wellbore and isolates the firing head when the pressure difference is at or approaches a designated pressure difference that could initiate the firing head. The pressure regulator includes a spring loaded piston that seals the firing head from the source pressure before the pressure difference activates the firing head.

摘要： A perforating gun system having a relief system for relieving high pressure during unexpected high temperature or situations that may produce rupture of the gun body. The relief system may be responsive either to high temperatures as well as high pressures. In the high temperature situation, the relief system has a fuseable link that melts thereby allowing movement of a piston to open vent communication between the inside of a gun body in the ambient conditions. Similarly, a pressure device includes a piston responsive to pressure that moves under high pressure within the gun body thereby exposing a port enabling communication between the inside of the gun body and the ambient conditions.

摘要： One embodiment of the present invention discloses a system for use with a downhole tool while perforating deviated portions of subterranean wellbores. The system involves a swivel connection attaching subsequent segments of the downhole tool which increases the overall flexibility of the downhole tool. The swivel connection allows sections of the downhole tool to pivot with respect to the next adjacent section.

摘要： A perforation gun is secured to the inside bore of a well completion tube by a releasable connection module. The connection module mechanism includes radially expanding anchor dogs that are retained at an expanded position by a latching mechanism that may be released, alternatively, by combustion gas or by wireline. When the perforation gun is discharged, gas from the discharge combustion displaces a retaining piston. Displacement of the retaining piston releases a latch pin and allows the gun weight to shift a secondary release sleeve. Shift of the secondary release sleeve releases a latch dog retention pin and hence, releases the anchor dogs from a meshed connection with the completion tube. The secondary release sleeve may also be shifted by the upward pull of a wireline.

摘要： A perforating gun can be conveyed on tubing and fired while disconnected from the tubing. The gun is retained to a running tool at the lower end of the tubing in a locked position. Actuating a plunger by pressure, a weight bar or other techniques, breaks a rupture disc and allows use of hydrostatic pressure to stroke a piston and defeat the lock between the gun and the running tool. Upon exposure of ports on the gun to wellbore hydrostatic due to movement out of the running tool, the firing sequence in the gun is initiated. The weight of the gun, as well as hydrostatic or applied pressure in the wellbore, drives the perforating gun out of the running tool.

摘要： A well completion procedure and apparatus comprises a first assembly that includes production tubing combined with a production packer and an internal bore latching profile. A second assembly comprises an explosive perforating gun secured to a latching mechanism. The perforating gun and latching mechanism are dimensioned to freely traverse the flow bore of the production tubing for downhole retrieval and return after the packer is set. The latching mechanism may be released by discharge of the gun.
