Abstract: A method and apparatus for circulating fluid in a wellbore includes a bottom sub 130 having a bottom sub port and a mandrel 35, wherein the mandrel 35 substantially forms an inner bore of the circulating tool and includes a mandrel port. The circulating tool may also include an activation piston 46 that is movable in a first direction and a port piston 64 movable in a second direction when the activation piston 46 moves in the first direction. The circulating tool may further include an inner sleeve 90 coupled to the port piston 64 and movable with the port piston, the inner sleeve 90 having an inner sleeve port in selective communication with the mandrel port. When the inner sleeve port is in communication with the mandrel port at least partially, circulating fluid is allowed to flow through the bottom sub port to the wellbore.

Abstract: A method and apparatus (100) for removing debris from a wellbore using a cleaning tool. The tool may comprise an inner mandrel (17) and a cup member (20) coupled to the inner mandrel. The cup member is moveable between a collapsed position where fluid may flow across the exterior of the cup member, and an extended position where fluid is diverted into a flow path disposed between the inner mandrel and the cup member. The fluid is diverted through a filter member (30) that is coupled to the inner mandrel below the cup member.

Abstract: A method of drilling a wellbore includes drilling the wellbore by injecting drilling fluid through a drill string extending into the wellbore from surface and rotating a drill bit of the drill string. The drill string further includes a circulation sub having a port closed during drilling. The drilling fluid exits the drill bit and carries cuttings from the drill bit. The drilling fluid and cuttings (returns) flow to the surface via an annulus formed between an outer surface of the tubular string and an inner surface of the wellbore. The method further includes after drilling at least a portion of the wellbore: halting drilling; sending a wireless instruction signal from the surface to a downhole portion of the drill string by articulating the drill string, acoustic signal, or mud pulse, thereby opening the port; and injecting drilling fluid through the drill string and into the annulus via the open port.
Abstract translation: 钻井井的方法包括通过从钻井表面延伸入井眼的钻柱喷射钻井液并旋转钻柱的钻头来钻井井。 钻柱还包括在钻孔期间具有关闭的端口的循环子系统。 钻井液离开钻头，并从钻头中携带钻屑。 钻井液和钻屑（返回）通过形成在管柱的外表面和井眼的内表面之间的环形空间流到表面。 该方法还包括在钻井井的至少一部分之后：停止钻孔; 通过铰接钻柱，声信号或泥浆脉冲，从钻井平台的表面向井下部分发送无线指令信号，从而打开端口; 并且通过钻柱注入钻井液并经由开放端口进入环形空间。

Abstract: A jar up, bump down hydraulic drilling jar is disclosed. A hydraulic tripping valve (46) arrangement permits the storage of large amounts of static force before releasing a hammer (56) to strike an anvil surface (58) with substantial force. The hammer (56) is positioned on the mandrel (8) and interacts with the anvil surface (58) in the housing (10) to deliver upward jarring forces, to the drill string. During the downward jarring movement, the tripping valve (46) is opened to prevent pressure buildup and accidental jarring; thus, a single acting drilling jar is formed.

Abstract: The present invention generally provides a downhole tool with an improved means of transmitting data to and from the tool through the use of wired pip e capable of transmitting a signal and/or power between the surface of the wel l and any components in a drill string. In one aspect, a downhole tool include s a body, and a mandrel (110) disposed in the body and movable in relation to the body. A conducive wire (135) runs the length of the body and permits signals and/or power to be transmitted though the body as the tool changes i ts length.
