摘要： A system and method of drilling and/or perforating uses a laser beam to remove material, such as to perforate the casing, cement and formation or drill a well bore. The system and method can further or alternately encompass material analysis that can be performed without removing the material from the well bore. The analysis can be performed apart from or in connection with drilling operations and/or perforating the casing, cement and formation. The analysis can be used in a feed back loop to adjust material removal, adjust material analysis, determine the location of future material removal, and for other uses.

摘要： A mud pulser controlled by a field applied to an electroactive fluid. The electroactive fluid is employed to act as a rapid-response brake to slow or interrupt the rotation of a mud motor or mud siren, thus creating pressure pulses in a circulating fluid. In certain embodiments, the electroactive fluid is used as a direct brake acting on a shaft rotating in a volume of electroactive fluid where the shaft is coupled to the mud motor or siren. The application of a field to the electroactive fluid impedes the rotation of the shaft, thus slowing the mud motor and creating a pressure pulse in the circulating fluid. In another embodiment, a Moineau pump circulating an electroactive fluid is coupled to the mud motor. The application of a field to the electroactive fluid slows the rotation of the pump, thus slowing the mud motor and creating a pressure pulse in the circulating fluid.

摘要： Methods of controlling a downhole tool in a well are disclosed wherein pressure change signals are introduced into a column of fluid standing in the well. The command signal includes at least one high level pressure change applied to the column of fluid. The high level pressure change includes a change from a first value to a second value, with the second value being at least about 1,000 psi above hydrostatic pressure of the column of fluid in the well, and with pressure being maintained at the second value for an interval of time corresponding to information stored in a control system of the downhole valve. A number of suitable command signal formats are disclosed, particularly including pressure drop signals.

摘要： A hydraulic system is provided for an electronically controlled downhole testing tool. The tool operates on a pressure differential between the well annulus and a substantially atmospheric pressure dump chamber defined in the tool. Power passages communicate a power piston with the well annulus and the dump chamber. Normally closed electric solenoid control valves are disposed directly in the power passages to control fluid flow therethrough. A pressure regulator regulates the pressure differential across the electric solenoid control valves.

摘要： An annulus pressure responsive tool is temporarily deactivated so as to no longer be responsive to changes in well annulus pressure. The tool includes a tool housing with a power piston slidably disposed in the housing. A first pressure conducting passage in the housing communicates the well annulus to one side of the power piston. A reference pressure means is disposed in the housing for providing pressure to the second side of the power piston. Thus, a pressure differential is created across the power piston. Also, a selectively operable temporary deactivating means is provided so that the power piston is no longer responsive to changes in the well annulus pressure.
