摘要： An injection manifold for use in injecting fluid into a well and method of use. Several embodiments of the apparatus are shown. In each embodiment, a bypass valve is used to control the discharge pressure of a pump, and a throttling valve is used to control the fluid injection flow rate to the well in response to a flow rate measured by a flow meter. In a first embodiment, the throttling is carried out manually. In a second embodiment, the throttling is carried out automatically by a controller which compares a flow rate signal from the meter with a predetermined flow rate set point and sends a corresponding output signal to an actuator of the throttling valve. A third embodiment is a combination manifold which may also be used for flowback tests from the well. In this third embodiment, the electronic controller may also be used to control the flow rate during the flowback test in response to a flow rate signal from the flow meter. A method of injecting fluid into a well using the apparatus is also disclosed.
摘要翻译：用于将流体注入井中的注入歧管和使用方法。显示该装置的几个实施例。在每个实施例中，旁路阀用于控制泵的排出压力，并且使用节流阀来响应于由流量计测量的流量来控制到井的流体喷射流量。在第一实施例中，手动进行节流。在第二实施例中，通过将来自仪表的流量信号与预定流量设定点进行比较的控制器自动执行节流，并将相应的输出信号发送到节流阀的致动器。第三实施例是组合歧管，其也可以用于来自井的回流测试。在该第三实施例中，电子控制器还可以用于响应于来自流量计的流量信号来控制回流测试期间的流量。还公开了使用该装置将流体注入井的方法。

摘要： A core holder for testing core permeability includes a modular sleeve comprising a series of sleeve segments aligned longitudinally. Port rings positioned between the sleeve segments have radial holes to allow conditions within the core-receiving cavity formed by the sleeve segments and the port rings to be monitored from outside the core holder. The port rings and the sleeve segments are disposed within a housing, and spacer rings are received about the sleeve segments to support the sleeve segments and port rings within the housing. Conditions within the modular sleeve may be monitored through instruments connected to holes in the housing communicating with the holes in the port rings.
摘要翻译：用于测试芯渗透性的芯保持器包括包括纵向排列的一系列套筒段的模块化套筒。定位在套筒段之间的端口环具有径向孔，以允许由套筒段和端口环形成的芯容纳腔内的状态从芯保持器的外部监测。端口环和套筒段设置在壳体内，并且间隔环围绕套筒段容纳以支撑壳体内的套筒段和端口环。可以通过连接到壳体中与孔中的孔连通的孔的仪器来监视模块化套筒内的状态。
