摘要： Methods and apparatus for downhole monitoring are provided by interrogating an unmodified optic fibre (102) arranged along the path of a well bore (106) to provide a distributed acoustic sensor and sampling data gathered from a plurality of contiguous sensing portions of the fibre. The sampled data is processed to determine one or more well bore parameters. The well bore parameters may comprise a well condition profile, and may be obtained in response to an acoustic stimulus.

摘要： Apparatus and methods for controlling and communicating with one or more tools in a downhole tool string including a tractor, an auxiliary tractor tool, a logging tool, a safety sub, a release mechanism, a unit containing sensors for monitoring downhole conditions, a setting tool, and a perforating gun. Also provided are apparatus and methods for controlling and communicating with one or more perforating guns, release devices, and explosive devices in a string to be lowered into a wellbore. Control and communication are accomplished by sending signals from the surface to control switches in the control units on the tool, with redundant switches for safety, to state machines in the respective control units, each state machine returning a signal verifying switch status to the surface. Control and power functions are accomplished with voltage of different polarities for safety.

摘要： Downhole tools (15) and systems can be actuated chemically by placing a chemical sensor (14) downhole and introducing a chemical slug (16) into fluids being pumped downhole. When the slug reaches the sensor a reaction in the sensor may be employed to trigger an event (e.g., actuation) or may cause a count to increase by one on its way to a full count an actuation of a tool or a system downhole.

摘要： A safety mechanism and method for downhole perforating are disclosed. In one example, a mechanical firing head includes a firing pin carried on a pin carrier within a housing. The firing pin is movable from a retracted position to a firing position for striking an explosive initiator. A retention member retains the firing pin in the retracted position with the safety member in the armed position. A safety member is biased to a safety position that additionally blocks movement of the firing pin. The safety member is moveable to an armed position that unblocks movement of the firing pin in response to an arming pressure supplied to the housing bore. The retention member releases the firing pin in response to a firing pressure supplied to the housing in excess of the firing pressure.

摘要： A perforating apparatus and method are disclosed wherein voids and inclusions may be configured to promote fragmentation of the charge case into pieces of less than a target size. In one example, the charge case of a shaped charge has a plurality of inclusions of a material interspersed with a plurality of voids of the material to promote fragmentation of the charge case. The inclusions and voids may be disposed along the periphery, such as along a mounting flange. In some examples, the voids may be holes of any of a variety of shapes, geometries, and positioning formed in the parent material of the charge case. In other examples, pieces of hardened material may be embedded in the parent material of the charge case to displace the parent material as well as to initiate probable locations of fragmentation.
