摘要： A downhole well tool is provided which includes a shifting sleeve for opening a flow communication port. The well tool includes first and second primary seal elements positioned upstream and downstream, respectively, of the port as well as upstream and downstream of the threaded connections between the well tool and sections of tubing forming the well flow conduit. A fluid diffuser element may be included to abate flow damage across the primary seal elements during the shifting of the sleeve. A method of selectively transmitting fluid incorporating said well tool also is disclosed.

摘要： Apparatus and method are provided for washing apparatuses in use of remedial tubing. A cylindrical housing has a fluid expansion chamber with fluid passageways communicating between the housing and the chamber. A turbulating sleeve freely rotates relative to the housing. Compression ports permit fluid to be transmitted through the housing, the passageways and into the chamber for injection through the ports to activate rotary motion of the sleeve for turbulizing washing action. A second housing is provided on the apparatus having normally closed wash ports which are angularly directed toward the remedial tubing and rearwardly relative to the apparatus. The wash ports are normally closed and may be opened, selectively, and when open, fluid flow through the apparatus is directed only through the rearwardly directed wash ports to drive particulate matter impacted exterior of the tubing and rearwardly of the apparatus from the apparatus.

摘要： Two frame sections are hingedly attached at their top and each frame section contains a pair of wheels at the bottom. One of the frame sections consists of a pair of laterally spaced parallel side rails having horizontal steps disposed therebetween. The other frame section contains a pair of parallel spaced channel bars on which ride a vertically movable platform. The platform can be hoisted along the channel bars by use of a hand crank and winch assembly. The two frame sections can be folded together for use as a conventional hand truck or the frame sections can be folded apart and the wheels locked for use as a stepladder.

摘要： A plurality of mounting frames are provided and have front and rear faces. Each of the frames is defined by at least three elongated interconnected peripheral sides and at least one side of each frame includes a recess formed therein opening outwardly of the rear face of the frame. A connecting member is provided and includes a panel-like body member having front and rear faces. The body member includes at least two spaced projections projecting outwardly from the front face thereof and the frames are disposed in side by side substantially coplanar relation with the sides thereof provided with recesses disposed in juxtaposition. The body member is positioned with its front face closely opposing the rear faces of the frames and with the projections removably frictionally telescoped into adjacent recesses of the frames and the connecting member thereby retaining the frames against separation. The frames may be of the same or different shape and may be of different sizes. Further, each side of each frame may include a plurality of longitudinally spaced recesses opening outwardly of the rear face thereof whereby adjacent frames may be secured in adjusted positions relative to each other.
摘要翻译：设置多个安装框架并具有前后表面。每个框架由至少三个细长的相互连接的外围边限定，并且每个框架的至少一个侧面包括形成在框架的后表面的外侧的凹部。提供连接构件，并且包括具有正面和背面的面板状本体构件。主体构件包括从其前表面向外突出的至少两个间隔开的突出部，并且框架与其设置有并置设置的凹部的侧面基本上共面地并排设置。主体部件定位成其前表面紧密地与框架的后表面相对，并且突出部可移除地摩擦地伸缩到框架的相邻凹部中，并且连接构件从而保持框架不会分离。框架可以具有相同或不同的形状并且可以具有不同的尺寸。此外，每个框架的每个侧面可以包括从其后表面向外开口的多个纵向间隔开的凹槽，从而相邻的框架可以相对于彼此固定在调节位置。
