摘要： A method and apparatus for perforating oil well casing in a well bore, with particular advantage in highly deviated well bores, uses a perforating gun assembly (15) run into the well bore (10) using the production tubing (12). A sliding sleeve (14) is connected in the tubing above the gun and a packer (13) is run in for setting above the sliding sleeve and gun. The assembly is run into the well bore until the gun extends into the highly deviated portion of the bore where the well casing is to be perforated. The packer is set into place, isolating that portion of the well bore below the packer from that portion above the packer, and the sliding sleeve is opened using a wireline or other means. The well bore below the packer is pressurized through the tubing to ensure that the packer is properly set. The pressure is then allowed to bleed off and the sliding sleeve is closed. The gun uses a differential pressure-actuated firing head which is actuated upon a predetermined differential pressure between the production tubing bore and the annulus between the tubing and the casing. Thus, a well casing can be perforated using relatively low values of actuating pressure, which provides greater control over perforating conditions such as underbalance.

摘要： An annulus pressure responsive tester valve includes a tool housing (12) having a flow passage (14) disposed therethrough. A ball valve (64) is disposed in the flow passage and rotatable between closed and open positions. An actuating mandrel (102) is operably connected to the ball valve. An annular power piston (146) is disposed within the housing and reciprocates relative to the housing in response to changes in well annulus pressure. A lug and slot ratchet assembly (170) operably connects the ball valve with the power piston for moving the ball valve between its closed and open positions in response to movement of the power piston within the housing.

摘要： A pressure operated downhole tool, eg circulation valve, has an operating element (60) and operating means, eg power mandrels (42,46). When a first predetermined pressure difference is established between the annulus and the interior of the tool, the operating means will operate the operating element but only if a safety device (44) has first been actuated. The safety device is actuated by a second predetermined pressure difference in an opposite direction to the first pressure difference. In one arrangement, the tool comprises a housing (31); a circulating valve (40) comprising a circulation port (62) formed through a wall of said housing and a valve mandrel (60) slidably received in said housing for blocking said circulating port in a first position and exposing said circulating port in a second position for permitting a flow between the interior and exterior of said housing, said valve mandrel being releasably maintained in said first position; valve piston means (90) slidably received in said housing for moving said valve mandrel to said second position in response to an internal pressure increase applied from within said housing; and a safety mandrel (96) slidably received in said housing; said safety mandrel having a first position in which said valve piston means is prevented from moving said valve mandrel to said second valve mandrel position and a second position in which such movement is permitted, said safety mandrel being moved from said first safety mandrel position to said second safety mandrel position responsive to an increase in pressure exterior of said housing.

摘要： A downhole tool for perforating a well and obtaining fluid samples therefrom, comprises a retrievable packer (20), perforating guns (24) and a sampler (22) disposed between the packer and guns which is adapted for entrapping a fluid sample without flowing well fluids into the tool string. An operating piston is slidably disposed in a cylinder above the packer and is used to actuate a sampler valve in the sampler. A seal ensures that all portions of a sampling chamber in the sampler are disposed below the packer. The operating piston is actuated in response to a pressure differential between a well annulus above the packer and an internal pressure in the tool. The sampler includes a plurality of sampler modules disposed in the sampling chamber. Each of the sampler modules includes a valve which automatically closes after a predetermined volume of fluid fills a sampler module chamber defined in the sampler module.

摘要： A lost-motion valve actuator for use in a wellbare closure valve, enables the valve to be run in a testing string into a well in an open mode, pressure to be applied to the well annulus surrounding the string without cycling the valve, subsequent reduction in the pressure, closure of the valve subsequent to the initial pressure increase, and subsequent opening of the valve with pressure increases and closure with pressure decreases. Thus, the bore closure valve can subsequently respond in a normal manner (open on pressure increase, close on pressure decrease) to pressure changes in the annulus subsequent to the first pressure increase/decrease cycle. An actuator of the invention comprises connector means (42, 144) movable longitudinally to open and close a valve, a mandrel (192) movable longitudinally under the influence of well pressures, and locking dogs (182) to connect and disconnect the mandrel and connector means to effect opening and closing of the valve in response to well pres-sures.

摘要： A downhole tool apparatus has a housing (12) with a compression chamber (232) defined therein. A fill passage (234) is disposed through the housing for placing the compression chamber in open flow fluid communication with a well annulus (236) so that well fluid may flow into the compression chamber as the apparatus is lowered into a well. An isolation valve (242) selectively closes the fill passage to trap well fluid in the compression chamber. An operating element (162) is operated by an actuating piston (140) slidably disposed in the housing. A first side of the actuating piston is in fluid pressure communication with the compression chamber so that a volume of the compression chamber is decreased when the actuating piston moves between first and second position thereof relative to the housing. An injection passage (286) is preferably provided for injecting pressurized gas into the compression chamber at a location within the compression chamber such that the injected gas will directly contact at a gas-well fluid interface an upper surface of well fluid that flows into the compression chamber. The compression chamber is preferably primarily defined by an elongate diametrically irregular annular space, and the gas-well fluid interface moves upward past a number of irregular diameters of this diametrically irregular elongated space, as the apparatus is lowered into a well.

摘要： A fluid pressure actuated apparatus for use downhole in a borehole comprises means such as a piston 150 for producing a force in response to a fluid pressure differential between well annulus pressure and a pressure source (above disc 36 in valve 100) isolated from the well annulus pressure; and means such as piston 122 by which extra force is applied to the force producing means in response to elevation of the pressure in a region 132 previously isolated from well annulus pressure. The force producing means may be arranged to operate a valve (36). The force producing means can be arranged to move initially at a first speed and then to surge as the extra force is applied.
