摘要： A downhole tool apparatus for use in a well includes a housing having a cylindrical chamber defined therein. A power piston is slidably disposed in the cylindrical chamber and divides the cylindrical chamber into first and second chamber portions on opposite sides of the power piston. First and second explosive charges are contained within the housing and communicated with the first and second chamber portions on opposite sides of the power piston. Firing of the first explosive charge moves the power piston in a first direction. Firing of the second explosive charge moves the power piston back in a second direction opposite the first direction. Thus, the operating power for a downhole tool is provided by selective firing of explosive charges which provide the operating pressure to move the power piston of the tool.

摘要： A well fluid sampling apparatus provides a time delay after actuation of the tool and before a sample is taken. The tool is operated by well pressure acting on a piston. The piston is initially hydraulically blocked so that it cannot move. The time delay is provided after the piston begins moving. Additional time delay devices can optionally be included.

That differential pressure is applied across a power transfer element to operate the downhole tool.

摘要： Integrated drilling and evaluation systems and methods for drilling, logging and testing wells are provided. The drilling and evaluation systems are basically comprised of a drill string, a drill bit carried on a lower end of the drill string for drilling a well bore, logging while drilling means included in the drill string for identifying subsurface zones or formations of interest, packer means carried on the drill string above the drill bit for sealing a zone or formation of interest below the packer means, and a fluid testing means included in the drill string for controlling the flow of well fluid from the zone or formation of interest into the drill string. The drilling and evaluation systems and methods for using the systems allow one or more subsurface zones or formations of interest in a well to be drilled, logged and tested without the necessity of removing the drill string from the well.

摘要： An electric coupling for two electric circuits in a well includes an electric contact and a contact receiver connected to respective ones of the circuits so that a contact/receiver pair is formed when the contact and receiver are moved together The receiver is sealed by a sealing member. The sealing member is disposed so that it is penetrated by the contact when the contact and receiver are moved together. A coupling including two such pairs is preferably used to connect two electric wires in the well to form a current conductive loop linking two electric coils. One of the coils is adapted to be moved in the well relative to the other coil which is adapted to be fixed in the well. In a preferred embodiment, one coil is on a wireline tool and the other coil is on a downhole tool. The current conductive path established across an intervening space between the tools is electrically insulated from the bodies of the tools and preferably has a resistance sufficiently low that the current conductive path is not effectively short-circuited by fluid in the intervening space which the path crosses.

摘要： A downhole electrical power supply apparatus has a high fluid pressure source zone and a low fluid pressure discharge zone each defined at least partially within the apparatus. A fluid powered engine provides rotational mechanical output and is powered by fluid flowing from the source zone through the engine to the discharge zone. An electrical powered generator converts the rotational mechanical output of the engine into electrical output.

摘要： A well system and associated method can include an acoustic generator which can be used to excite a formation with acoustic waves transmitted from the acoustic generator. Another well system and associated method can include an acoustic generator which can transmit acoustic waves into cement surrounding a casing. Another well system and associated method can include an acoustic generator which can be used to transmit acoustic waves into an annulus surrounding a well screen during or after a gravel packing operation. Another well system and associated method can include an acoustic generator which can be connected in a drill string in close proximity to a drill bit, with the acoustic generator transmitting acoustic waves into a formation ahead of the bit.
