摘要： An apparatus (100) for actuating a hydraulically controllable device (102) disposed in a wellbore is disclosed. The apparatus (100) comprises a downhole hydraulic fluid source (134), a hydraulic fluid passageway (136) providing a communication path between the downhole hydraulic fluid source (134) and the hydraulically controllable device (102), a valve (144) disposed within the hydraulic fluid passageway (136) and a downhole electronics package (138). The downhole electronics package (138) receives a signal from the surface to operate the valve (144) from the closed position to the open position such that hydraulic pressure from the downhole hydraulic fluid source (134) actuates the hydraulically controllable device (102).

摘要： A fracturing/gravel packing tool with variable direction and exposure exit ports. A system for delivering an erosive flow into a subterranean well includes a port displacing in the well while the erosive flow passes through the port. Various displacement devices may be used in the system to displace the port.

摘要： A backup shoe for a well packer provides high pressure sealing capability without requiring a large setting force or setting stroke of the packer. In a preferred embodiment, a backup shoe has an inner portion with a relatively thin cross-section and an outer portion with a relatively thick cross-section. Additionally, the inner portion has a pivot point between its ends. In a preferred embodiment of a packer utilizing the backup shoe, an element retainer axially contacts the inner portion adjacent its pivot point, and a seal element axially contacts an inner sloping surface formed on the outer portion.
摘要翻译：用于井封包机的备用鞋提供高压密封能力，而不需要大的设定力或打包机的设定冲程。在优选实施例中，支承靴具有相对薄的横截面的内部部分和具有相对较厚横截面的外部部分。此外，内部部分在其端部之间具有枢转点。在利用支承靴的封隔器的优选实施例中，元件保持器轴向地接触靠近其枢转点的内部部分，并且密封元件轴向接触形成在外部部分上的内部倾斜表面。

摘要： A packer for use in subterranean wellbores provides efficient utilization of its cross-sectional area with mechanisms therein for anchoring, sealing, and torquing through the packer. In a preferred embodiment, a retrievable packer has a tubular mandrel, rubbers disposed on the mandrel, upper and lower compression members axially straddling the rubbers, a barrel-type casing slip, upper and lower wedges axially straddling the casing slip, a release mechanism, and a series of threaded load-distributing components which help to prevent collapse of the mandrel.
