摘要： Methods and apparatus for perforating a formation in a wellbore without perforating a well bore casing. The methods and apparatus include an external casing perforating device configured so as not to perforate the casing. The interior of the perforating device serves as a fluid flow path between the casing and the formation following perforation and a valve in the casing selectively opens and closes the flow path.

摘要： An actuating tool which is conveyed into a tubing string to attach to portions of an emplaced perforating gun. The tool includes an actuator with an electronic delay timer and an explosive device. The tool attaches to an emplaced perforating gun and detonates it by initiating an explosive charge along a complete explosive pathway formed between the actuator and gun, the actuator includes a tandem piston arrangement functional at most existing hydrostatic pressure levels, but nonfunctional at or near the surface of the wellbore. The tool may be withdrawn from the tubing string for a backup detonation tool to be placed into the tubing string to detonate a secondary firing head.

摘要： Methods of perforating a well using coiled tubing conveyed perforating guns are disclosed. A perforating tool string includes a coiled tubing string, a perforating gun, a releasable gun hanger, and a pressure responsive release connecting the coiled tubing string to the perforating gun. The perforating tool string is lowered into place within the well and then the gun hanger is actuated by reciprocating motion of the coiled tubing string without rotating the coiled tubing string, thereby setting the gun hanger in the casing. Fluid pressure is then increased in the coiled tubing string to actuate the pressure responsive release to release the coiled tubing string from the perforating gun. The coiled tubing string and pressure responsive connector may then be retrieved from the well prior to firing the perforating gun. The perforating gun is subsequently fired by a pressure responsive firing head to perforate the well casing, and the perforating gun then automatically drops to the bottom of the well casing.

摘要： The present invention presents a method and apparatus for perforating a well in response to fluid pressure in a first tubing string while establishing a pressure balance in response to pressure in a second string, or in the well casing, through which the well will be produced. Additionally, redundant firing heads may be provided for perforating guns utilized to assure optimal reliability of the system. One or more perforating equipment assemblies may be employed in a tool string, each of which includes redundant firing mechanisms responsive to pressure in the tool string. Additionally, a firing head assembly is utilized which is initially responsive to pressure in the tool string, but which is subsequently actuated by annulus pressure. The firing head is suitable for use with much lower annulus pressures than are utilized with conventional hydraulically actuated firing head assemblies.

摘要： A vent subassembly includes a vent body having an opening which is covered or uncovered dependent upon the location of a vent sleeve relative to the vent body. The vent subassembly can be connected below a packer, and the vent sleeve can be connected to a perforator so that movement of the vent sleeve is concurrently communicated to the perforator, such as for initiating the firing of the perforator. The vent sleeve is moved by an actuator subassembly, which is to be connected above the packer if the vent and actuator subassemblies are used with a packer. The actuator subassembly has a piston housing, a piston slidably disposed in the piston housing, and a connector string extending from the piston to the vent sleeve. The piston is responsive to a differential pressure existing between the annulus outside the actuator subassembly and an interior pressure within the actuator subassembly.
