摘要： A completion apparatus for completing a wellbore comprises a) a tool to alternatively open and close a throughbore of the completion; b) a tool to alternatively open and close an annulus defined between the outer surface of the completion and the inner surface of the wellbore; c) a tool to alternatively provide and prevent a fluid communication route between the throughbore of the completion and the said annulus; and d) at least one signal receiver and processing tool capable of decoding signals received relating to the operation of tools a) to c). The apparatus is run into the well bore, tool a) is operated to close the throughbore; the pressure within the fluid in the tubing is increased to pressure test the completion; tool b) is operated to close the annulus; tool c) is operated to provide a fluid communication route between the throughbore and the annulus; tool c) is then operated to prevent the fluid communication route between the throughbore and the annulus such that fluid communication is prevented; and tool a) is operated to open the throughbore.

摘要： A fluid flow control system for downhole use in an oil or gas well has a choke with a conduit having an inlet and an outlet, and a flow restrictor comprising first and second choke members 10,20, one of which rotates relative to the other to choke or promote flow. The first and second choke members 10,20 are axially spaced from one another, and have mating faces that are optionally planar, and are axially stacked in the choke. The choke is operated by a shifting tool 50, which grips the inner surface of the rotating choke member 10, and rotates it relative to the other 20, in order to vary the flow. The shifting tool 50 is adapted to be deployed on a line or string of tools passing through the bore of the choke.
摘要翻译：用于油井或气井的井下使用的流体流量控制系统具有带有具有入口和出口的导管的扼流器以及包括第一和第二扼流构件10,20的限流器，其中一个扼流构件中的一个相对于另一个旋转至阻塞或促进流动。第一和第二扼流构件10,20彼此轴向间隔开，并且具有任选平面的配合面，并且沿轴向堆叠在扼流器中。扼流器通过换挡工具50操作，换挡工具50夹紧旋转的扼流构件10的内表面，并相对于另一个20旋转，以改变流动。切换工具50适于布置在穿过扼流器的孔的工具的线或串上。

摘要： A method for completing a wellbore (1) comprises operating a) a tool (15) to alternatively open and close a throughbore (40) of the completion (4); b) a tool (13) to alternatively open and close an annulus (5) defined between the outer surface of the completion and the inner surface of the wellbore; c) a tool (11) to alternatively provide and prevent a fluid circulation route from the throughbore of the completion to the said annulus; and d) at least one signal receiver and processing tool (9) capable of decoding signals received relating to the operation of tools a) to c). The method entails running the apparatus is run into the well bore, and tool a) is operated to close the throughbore; the pressure within the fluid in the tubing is increased to pressure test the completion; tool b) is operated to close the annulus; tool c) is operated to provide a fluid circulation route from the throughbore to the annulus and circulate fluid through the production tubing and out into the annulus and back to surface; tool c) is then operated to prevent the fluid circulation route from the throughbore to the annulus such that fluid is prevented from circulating; and tool a) is operated to open the throughbore.
