摘要: A downhole tool system includes a first downhole tool and a second downhole tool. The first downhole tool includes a first controller operable to receive an actuation signal including a tone. The first controller actuates the first downhole tool if the tone is a first specified frequency and changes the first downhole tool to communicate the actuation signal to the second downhole tool if first downhole tool is not actuated in response to the actuation signal. A second downhole tool includes a second controller operable to receive the actuation signal. The second controller actuates the second downhole tool if the tone is a second specified frequency. The second frequency is different from the first frequency.

摘要: An explosive tool is disclosed. The explosive tool comprises a body structure, a charge, a detonator to ignite the charge via propagation of thermal energy, a pressure actuated safety to prevent propagation of sufficient thermal energy to ignite the charge when the pressure actuated safety is subjected to a surface pressure and to not prevent propagation of sufficient thermal energy to ignite the charge when the pressure actuated safety is subjected to at least a predefined pressure threshold, and a temperature actuated safety to prevent propagation of sufficient thermal energy to ignite the charge when the temperature actuated safety is subjected to a surface temperature and to not prevent propagation of sufficient thermal energy to ignite the charge when the temperature actuated safety is subjected to at least a predefined temperature threshold. The charge, the detonator, the pressure actuated safety, and the temperature actuated safety are contained within the body structure.

摘要: A system (100) for selective activation of explosive devices (126, 128, 130, 132) includes a surface controller (102), a downhole controller (106) operable to communicate bidirectionally with the surface controller over a first communication link (108) and a plurality of downhole remote units (114, 116, 118, 120) operable to communicate bidirectionally with the downhole controller (106) over a second communication link (112). One or more sensors (162) are operably associated with the downhole controller (106) and one of the explosive devices (126, 128, 130, 132) is operably associated with each of the downhole remote units (114, 116, 118, 120) such that, responsive to a detonation event, the sensors (162) detect the intensity level of the detonation which is communicated from the downhole controller (106) to the surface control (102) over the first communication link (108).

The apparatus includes an ambient-activated switch electrically coupled between the radiation source and the power source. The ambient-activated switch is to switch to an open position while a value for an ambient characteristic for the ambient-activated switch is at an ambient level for a surface of the Earth. The ambient-activated switch is to switch to a closed position while the value for the ambient characteristic for the ambient-activated switch is at a downhole ambient level, wherein the ambient-activated switch is to electrically couple the power source to the radiation source while in the closed position.
