摘要： A well conduit cutting and milling apparatus conveyable into and out of a well on coilable tubing using a tubing injection unit. The apparatus includes tubing or casing cutting arms which are radially extendable and retractable with respect to a cylindrical support body by pressure fluid operated pistons. The apparatus is made up of multiple end-to-end connected units including one which supports interchangeable cutting and milling arms and units which have radially extensible and retractable stabilizing arms which engage the inner wall of the tubing or casing to centralize and stabilize the apparatus during operation. The cutter and milling arms are modified for milling away a section of tubing by moving the apparatus in an upward or out of the well direction. The cutting elements are preferably cylindrical hard metal members which are supported on the arms for cutting away an end face of the tubing in a tangential direction of movement.

摘要： A fluid injection apparatus includes a portable base frame having a pumping mechanism and fluid container mounted thereon. A conduit connects the pumping mechanism to a spacer flange which can be interconnected between a blowout preventer and a choke manifold so that fluid can be readily injected into these two types of equipment. The apparatus and its interconnection between the blowout preventer and choke manifold provide a technique by which accumulated solid deposits within the blowout preventer can be blown back toward the well to prevent their passage into the choke manifold, thereby preventing blockage of the choke manifold. The apparatus and method of the present invention also permit fluids to be injected into the blowout preventer and choke manifold for such purposes as conducting pressure tests and for preventing freezing of the components of the blowout preventer and choke manifold.

摘要： A hydraulic jar device for use in through-tubing drilling and fishing operations which consists of an elongate tube having an upper hammer sub, a kelly cylinder and a hydraulic cylinder with central restrictor secured therebelow. A lower sub connects to the bottom end of the hydraulic cylinder. The sliding interior components are an upper mandrel secured to an anvil sub which, in turn, is fastened to an axial plunger, all of which are slidable down within the elongate tube. A metering ring retained on the plunger interacts with the central restrictor of the hydraulic cylinder to control force effected up and down jars that occur when the mandrel strikes the hammer sub on the down stroke, and when the anvil sub strikes the hammer sub bottom on the up stroke.

摘要： A system for externally testing a pipe joint connection utilizes a well known oil field apparatus with minor modifications to perform an important test of the hydraulic integrity of the pipe joint. A pair of hydraulically operated blowout preventor rams are connected by means of a pipe of sufficient length to accommodate the enclosure of a pipe joint connection. The connecting pipe forming the enclosure is aligned with the pipe opening in the rams. Thus the assembly is comprised of upper and lower rams with a pipe therebetween forming a test chamber. The lower rams are inverted so that the rams are closed, the connecting pipe forms a sealed chamber. A port is provided in the connecting pipe to permit fluid under pressure to be passed into the chamber when the rams are closed about pipe being tested. The test assembly is connected by a flange below the lower ram to the wellhead. As a string of pipe is passed into the well, the pipe joint connections are positioned in the chamber, the rams are closed, and fluid pressure is applied externally to the pipe joint. Measurement of fluid pressure decay determines if a leak exists.
摘要翻译： 用于外部测试管接头连接的系统利用公知的油田设备进行小的修改以对管接头的液压完整性进行重要测试。 一对液压操作的防喷器柱塞通过足够长度的管道连接以容纳管接头连接的外壳。 形成外壳的连接管与公柱中的管道开口对齐。 因此，组件由上和下公柱组成，其中管之间形成测试室。 下游的公柱倒置，使得公柱关闭，连接管形成一个密封的室。 在连接管中设有一个端口，以便当公制件关闭被测试的管道时，允许压力下的流体进入腔室。 测试组件通过下冲杆下方的凸缘连接到井口。 当一串管道进入井中时，管接头连接件位于腔室中，柱塞被关闭，并且流体压力在管接头外部施加。 流体压力衰减的测量确定是否存在泄漏。
