The up-thrust bearing includes: a thrust driver longitudinally and torsionally connected to the receptacle shaft; and a thrust carrier connected to the adapter. The centrifugal pump includes: a diffuser connected to the adapter; a pump shaft torsionally connected to the receptacle shaft; and an impeller connected to the pump shaft.

摘要： A gravel pack assembly includes screen sections with a packer between them. A first screen section communicates an uphole annulus with the assembly's interior passage, and a second screen section communicates a downhole annulus with the interior passage. A housing of the packer has an internal bore communicating with the assembly's interior passage and has an internal bypass communicating external ports with one another. A first packer element disposed between the external ports restricts gravel passage at least from the uphole to the downhole annulus. A second packer element disposed downhole from a second of the external ports is independently actuated to isolate fluid passage between the uphole and downhole annulus. One or more transport tubes communicate slurry from the uphole annulus to the internal bypass once the uphole annulus is packed with gravel.

摘要： A container for collecting water samples to determine dissolved gas includes a flask-type pouch with a spout. A removable cap and valve install on the spout. The valve includes an adapter that fits with an O-ring or other seal inside the mouth of the spout. The valve includes a valve element, which can be a one-way, self-closing type of valve, that fits with an O-ring or other seal inside the end of the adapter. A cap of the container fits over the adapter and affixes to the spout to hold the valve on the spout. In use, the cap can be removed so that the valve element and adapter can be removed for filling the pouch. Otherwise, the cap can remain in place so filling can be performed through the valve element. A tamper-evident ring on the cap may be provided to ensure the integrity of the sample contained in the flask.

摘要： A cementing port collar has an opening sleeve biased from a closed position to an opened position relative to the collar's exit port, and a first restraint temporarily holds the opening sleeve closed. The collar also has a closing sleeve biased from an opened position to a closed position, and a second restraint temporarily holds the closing sleeve opened. During cementing, the first restraint is electronically activated with a first trigger to release the opening sleeve opened so cement slurry can pass out of the collar's exit port to the borehole annulus. When cementing is completed, the second restraint is electronically activated with a second trigger to release the closing sleeve closed to close off the collar to the borehole so the cement can set. The restraints can include bands of synthetic fiber, which are burned by fuses activated by a controller of the collar responding to passage of RFID tags.

摘要： A downhole assembly for directionally drilling a borehole has a motor, a transmission, and a steering mechanism. The motor has a rotor driven in a stator by flow of drilling fluid therebetween. The transmission operatively couples the rotor to a drill bit for drilling the borehole. A flow control controls the flow of drilling fluid through an internal passage of the rotor. The flow control can thereby vary the drive of the rotor in a bit speed effect that preferentially cuts the wall of the borehole to achieve directional drilling. The flow control can also thereby create a differential pressure displacing the rotor along a longitudinal axis of the motor in a thrust effect. The steering mechanism responds to the displacement of the rotor and deviates a direction of the drill bit from the longitudinal axis of the motor to further achieve directional drilling. The bit speed effect, the rotor displacement, and the deviation are preferentially coordinated to coincide or at least operate together.
摘要翻译： 用于定向钻孔的井下组件具有马达，变速器和转向机构。 电动机具有通过其间的钻井液流动在定子中驱动的转子。 变速器将转子操作地连接到用于钻孔的钻头。 流量控制器控制钻井液通过转子的内部通道的流动。 因此，流量控制可以以优先切割钻孔的壁的位速效应来改变转子的驱动以实现定向钻井。 流量控制还可以由此产生以推力效应沿着电动机的纵向轴线使转子移位的差压。 转向机构响应转子的位移并使钻头的方向偏离电机的纵向轴线，以进一步实现定向钻孔。 位速度效应，转子位移和偏差优先协调以一致或至少一起操作。

摘要： A method of drilling a wellbore includes deploying a drill string into the wellbore through a casing string disposed in the wellbore. The casing string has a pressure responsive element and a hydraulic line in communication with the element and extending along the casing string. The method further includes: drilling the wellbore into a formation by injecting drilling fluid through the drill string and rotating a drill bit of the drill sting; and while drilling the formation, monitoring a pressure of the hydraulic line to ensure control of the formation.
