Abstract
A system for perforating a well includes a plurality of perforating guns suspended in the well from the wireline or coiled tubing. A downhole electronic command circuit is provided for firing each of the guns in response to a command signal from the surface. A conductor cable, which may be the wireline, extends from the surface to the downhole command circuit, such that command signals fire the guns in a selected order.
Claims20
A perforating system for perforating a well, the perforating system including a plurality of perforating guns suspended in the well from one of a wireline and coiled tubing, the perforating system further comprising:
- a downhole electronic command circuit for firing each of the plurality of guns in response to a respective command signal, the command circuit controlling the firing of the guns;
- a conductor cable, which may be the wireline, extending from the surface to the downhole command circuit for firing the guns in a selected order;
- and
- the command circuit including a fuse opening in response to the command signal when firing a gun and activating a switch for subseguently firing another gun.
A system for selectively activating a plurality of tools suspended in a well, the system comprising:
- a downhole electronic command circuit for firing each of the plurality of tools in response to a respective command signal, the command circuit including a fuse opened in response to the command signal to fire one of the plurality of tools and activating a switch for subsequently firing another of the plurality of tools;
- and
- a conductor cable extending from the surface to the downhole command circuit for firing the tools in the selected order.
A method of activating a plurality of tools suspended in the well from one of a wireline and coiled tubing, the method comprising:
- providing a downhole electronic command circuit to activate each of the plurality of tools in response to a respective command signal, the command circuit controlling the activation of the tools in response to opening a fuse in the command circuit in response to the command signal when firing one of the plurality of tools and activating a switch for subsequently firing another of the plurality of tools;
- and
- transmitting the command signal between the surface and the downhole command circuit to activate the tools in a selected order.
