摘要： A resettable well stimulation tool is lowerable into a well bore on a length of tubing through which pressurized fluid may be forced into the tool to inflate a packer portion carried by the tool and then discharge a stimulation fluid into a portion of the well bore sealed off by the packer portion. During the inflation cycle of the tool pressurized fluid is forced downwardly into an annular tool body inflation chamber that communicates with an inflatable packer carried by the tool body. A perforated tube member coaxially carried in the inflation chamber serves to vertically distribute the inflation pressure along the length of the packer and assure its even inflation. In a straddle packer embodiment of the tool inflation and stimulation passages extend internally through the tool and are sealingly separated by an internal crossover structure, with the inflation passage being in communication with upper and lower packer members. The internal inflation passage eliminates the previous necessity of communicating the upper and lower packers with inflation tubing externally coiled around the tool body. A longitudinally intermediate portion of the tool body has a telescoping expansion joint portion to compensate for the longitudinal forces exerted on the body by inflation of the packers. The expansion joint is biased, by both mechanical spring pressure and internal fluid pressure, toward a retracted position thereof.
摘要翻译：可重置的井刺激工具可以降低到一段管道上的井眼中，加压流体可以通过该管道被迫进入工具中，以使由工具承载的封隔器部分膨胀，然后将刺激流体排放到密封的井筒的一部分中通过封隔器部分。在工具的充气循环期间，加压流体被迫向下进入与由工具主体承载的充气封隔器连通的环形工具体充气室。同轴地承载在充气室中的穿孔管构件用于沿着封隔器的长度垂直分布充气压力并确保其均匀的充气。在跨越打包器的实施例中，工具膨胀和刺激通道在内部延伸穿过工具，并且通过内部交叉结构密封地分开，充气通道与上部和下部封隔器构件连通。内部充气通道消除了先前需要将上部和下部封隔器与外部盘绕在工具体上的充气管连通的需要。工具主体的纵向中间部分具有伸缩式膨胀接头部分，以通过封隔器的充气来补偿作用在身体上的纵向力。膨胀接头通过机械弹簧压力和内部流体压力被偏压到其缩回位置。

摘要： A wireless coiled tubing joint locator for locating joints or collars in a production tubing string. An electromagnetic coil assembly or giant magnetoresistive digital field sensor senses the increased mass of a pipe joint, and provides a signal to an electric circuit which generates a signal received by a pilot solenoid valve. The solenoid valve momentarily opens a pilot passageway which activates a piston to close a circulation port in the joint locator, resulting in an increase in a surface pressure reading observable by the operator. In one embodiment, a rupture disk is provided so that pressure cannot be applied to any downhole tool below the joint locator prematurely. A seat sleeve prevents premature communication of fluid to the rupture disk but can be opened by dropping a ball into the joint locator. A second embodiment may be used for either logging or washing operations or both. The electronic circuit can provide a selected one of a plurality of time delays. A fixed test period in the circuit delays activation of the time delay so that the joint locator may be tested before it is run into the well. The electric circuit and power supply are provided in a removable case.

摘要： A ball drop tool, for dropping a ball to a ball seat located in a tool, or tool string therebelow. The ball drop tool has an upper end adapted to be connected to the lower end of the coiled tubing string. The ball drop tool includes a housing with a ball drop cage positioned therein. The ball drop cage has a rocker arm pivotally attached thereto. The rocker arm can be pivoted so that a lower end thereof extends radially inwardly into an opening and will hold a ball in the cage. The cage will move downwardly in the housing until the lower end of the rocker arm is retracted from the opening, which will allow the ball to pass downwardly through the ball drop housing so that it can be received in a ball seat in a tool therebelow.

摘要： A heavy-duty logging and perforating cablehead for coiled tubing. The cablehead includes an upper and lower housing which are shearably connected by shear pins. An actuating piston is slidably disposed in the housing. When the piston is in a running position, the piston holds a lug in locking engagement with the upper and lower housings such that the shear pins cannot be sheared. When the piston is moved to a releasing position, the lugs are released so that the upper and lower housings may be separated, thereby shearing the shear pins. Actuation of the piston is accomplished by pumping fluid down the coiled tubing and through a flow path in the cablehead and by applying pressure to the piston.

摘要： A coiled tubing drilling hydraulic disconnect for use in disconnecting a tool from a length of tubing or other tool string. The apparatus has an upper housing and a lower housing with a splined ring threadingly engaged with the lower housing. A spline in the splined ring engages a spline on the upper housing so that torque may be transmitted therebetween. Lugs are disposed through windows in the lower housing below the splines, and a bushing is disposed between the splined ring and the lugs. Relative rotation between the upper and lower housings causes the splined ring to tighten against the bushing and lugs, thereby eliminating play therebetween. A lug prop disposed in the upper housing may be hydraulically actuated so that the lugs may move to a disconnect position, thereby releasing the upper housing from the lower housing. Because the windows are disposed below the splines, no torque or bending are applied to the windows, and the windows and lugs are shaped to minimize stress concentrations.

摘要： A packer apparatus with a circulating port. A housing of the packer has inflation passages, circulating passages, treating fluid passages, and equalizing passages defined therein. In a straddle packer embodiment, upper and lower packers are mounted on the housing on opposite sides of an outlet of the treating fluid passage. A circulation valve with a sliding differential pressure actuated valve sleeve is disposed below the packers. An inner mandrel is slidably received in the central opening of the housing. The mandrel has a mandrel bore and has upper inflation and circulating ports, lower inflation ports, upper and lower equalizing ports, a treating port and lower circulating ports, all of which communicate with the mandrel bore. The valve sleeve has a valve port. A lug and endless J-slot is operably associated with the housing and mandrel for controlling a telescoping position of the mandrel relative to the housing in response to reciprocation without rotation of the mandrel relative to the housing. The mandrel may also be used to lock the valve sleeve in a closed position. The lug and J-slot define a repeatable sequence of inflating (or deflating) position, intermediate position, circulating position, treating position, equalizing position, and ready position wherein the tool is ready to return to the original inflating position on the next telescoping stroke of the mandrel within the housing.
