    摘要： A method of cleaning debris from a string of production tubing in a well enables removal without pulling the string of rods that extend through the tubing. A rotary pump is suspended to a lower end of the tubing for pumping well fluid through the tubing to a wellhead at the surface. A motor assembly at the surface rotates the rods to drive the pump. A closure member is placed on a lower end of an elastomeric hose that will open when a selected level of internal fluid pressure is applied. The operator applies internal pressure to the hose at a pressure less than the selected level to increase rigidity of the hose. The operator inserts the hose through a port in a sidewall of the wellhead, the hose deflecting downward and into the tubing. At a desired point, the operator increases the internal pressure in the hose to open the closure member, then discharges a cleansing fluid into the tubing, which flows back up the tubing along with debris.

    摘要翻译： 在井中清洁一串生产管道中的碎屑的方法能够移除，而不会拉动延伸穿过管道的杆状物串。 旋转泵悬挂在管道的下端，以将井液通过管道泵送到表面的井口。 表面上的电机组件旋转杆来驱动泵。 闭合构件放置在弹性体软管的下端，当施加选定的内部流体压力水平时，其将打开。 操作者在小于所选水平的压力下对软管施加内部压力，以增加软管的刚度。 操作人员将软管穿过井口侧壁的一个端口，软管向下偏转并进入管道。 在所需的位置，操作员增加软管中的内部压力以打开关闭构件，然后将清洁流体排放到管道中，该管道与碎屑一起流回管道。

    摘要： A proppant for enhancing the recovery of petroleum from rock formations comprises pellets of sulphur and a binding and strengthening additive, preferably comprising cement. A process for manufacturing the proppant comprises first melting sulphur to form a liquid and forming a mixture of the liquid sulphur with cement powder. The mixture is then cooled and pelletized to form pellets of a sulphur and cement composite. The pellets are then dried and sorted by size.

    摘要： An acidizing composition and a method of acidizing a hydrocarbon bearing subterranean formation in the presence of ferric ions are provided. The acidizing composition includes a mineral acid solution, an electron donor agent, a primary electron transfer agent and a secondary electron transfer agent. The primary electron transfer agent is a source of vanadium ions. The secondary electron transfer agent is a source of iodide ion or iodine. The electron donor agent and primary and secondary electron transfer agents function together to reduce ferric ion present in the mineral acid solution to ferrous ion which in turn prevents ferric hydroxide and/or free sulfur from precipitating out of the solution and reduces the formation of sludge in crude oil in the formation.

    摘要： It has been discovered that fracturing fluid compositions can be designed for successful deep water completion fracturing fluid operations. These fluids must be pumped relatively long distances from offshore platforms to the reservoir, and they are often subjected to a wide temperature range. Under these conditions, it is necessary to inhibit the formation of gas hydrates in the fracturing fluid compositions, as well as to delay the crosslinking of the gels that are formed to increase the viscosity of the fluids prior to fracturing the formation. Preferably, two different gas hydrate inhibitors are used to ensure placement of a gas hydrate inhibitor in most parts of the operation. In addition, as with all offshore or deep water hydrocarbon recovery operations, it is important that the components of the fracturing fluid compositions be environmentally benign and/or biodegradable.

    摘要： A hand-operated machine tool is disclosed that rotationally drills or percussively chips or both. An embodiment of the hand-operated machine tool includes a toolholder that is used to hold tools having a grooved shank. The toolholder has a toolholder body and at least one radially moving locking member, for example a locking sphere, that is insertable into a groove in the tool and the locking member is radially locked in position by a retaining element that may be displaced by an actuating element to a position that radially releases the locking member. In an embodiment of the invention, the toolholder has at least one sealing device that seals at least one chamber outwardly surrounding the locking member. The sealing device includes at least one sleeve-shaped component that is separate from the actuating element and at least partially defines the volume referred to as the chamber.
