摘要： A downhole tool for removing debris from a wellbore comprises a mandrel and a shroud disposed around a portion of the mandrel. The mandrel includes at least one mandrel port in fluid communication with a mandrel bore. The shroud includes a cavity and a shroud port. Debris laden fluid is pulled into the shroud cavity by flowing fluid through the mandrel bore, out the mandrel port, into the shroud cavity, and through the shroud port. The debris-laden fluid is pulled into the shroud cavity due to a pressure differential created by the flow of the fluid through the mandrel port and out of the shroud port. As the debris laden fluid flows into the shroud cavity, the debris is captured within the tool.
摘要翻译：用于从井眼去除碎屑的井下工具包括围绕心轴的一部分设置的心轴和护罩。心轴包括与心轴孔流体连通的至少一个心轴端口。护罩包括腔和护罩口。通过使流体流过心轴孔，从心轴端口流入护罩腔，并通过护罩端口将碎屑载入流体拉入护罩腔。由于流体通过心轴端口并流过护罩端口而产生的压力差，将载满碎屑的流体拉入到护罩腔中。当载满碎屑的流体流入护罩腔中时，碎屑被捕获在工具内。

摘要： A valve and method of use wherein the valve includes a housing having an axial flowbore defined along its length. A lateral fluid flow port is disposed through the housing. A piston sleeve is disposed within the flowbore and is selectively moveable to block flow through the lateral flow port. The valve can be moved between operating positions wherein flow through the lateral flow port is blocked or allowed and axial flow through the flowbore is blocked or permitted.

摘要： A one trip method for cleaning an existing string while performing testing on the string allows in the same trip the drilling of additional wellbore. The cleanup equipment is retracted after the testing is completed so that it will not impede the advancement of the drill bit at the lower end of the string. The cleanup tools are typically extend for run in through the string and they can be collapsed by a technique such as dropping a ball to shift a sleeve to disable the piston assembly that holds the cleanup tools extended and allows them to be retracted using a return spring or other source of potential energy.
摘要翻译：在对字符串进行测试时清洁现有字符串的一次行程方法允许在同一行程中钻取附加的井眼。在完成测试之后，清理设备被收回，从而不会妨碍钻头下端的钻头的前进。清洁工具通常延伸穿过绳子，并且它们可以通过诸如落下球以移动套筒以使不使保持清洁工具延伸的活塞组件的技术被折叠，并且允许其使用复位弹簧缩回或其他潜在能量来源。

摘要： A fracturing operation is done in open hole without annular space isolation. The annular space is spanned by telescoping members that are located behind isolation valves. A given bank of telescoping members can be uncovered and the telescoping members extended to span the annular space and engage the formation in a sealing manner. Pressurized fracturing fluid can be pumped through the telescoped passages and the portion of the desired formation fractured. In a proper formation, cementing is not needed to maintain wellbore integrity. The telescoping members can optionally have screens. Normally, the nature of the formation is such that gravel packing is also not required. A production string can be inserted into the string with the telescoping devices and the formation portions of interest can be produced through the selectively exposed telescoping members.

摘要： A trigger device for setting a downhole tool (100) includes a retaining member (26) that restricts the downhole tool from setting until it is properly positioned within the well and a force acts upon an actuating member (12). The retaining member includes an extrudable material (27) that extrudes through an orifice when the force acts upon the actuating member. The extrudasble material is preferably one that moves at a known rate so that the amount of time necessary for the downhole tool to set is pre-determined.

摘要： An isolation assembly for downhole injection use is described that features at least one isolation device (2) mounted on a tubular (4) so that when injection fluid changes the tubular temperature which can cause a length change in the tubular, an anchor (3) for the tubular is provided to resist such a dimension change. The result is that the isolation device such as a packer can be left undamaged and retaining its sealing integrity. The anchor can be an inflatable or telescoping pistons (9) disposed to grab in open hole. When using telescoping pistons, their placement on the liner and their pattern can meet the desired locations where grip is enhanced. Use of cement inflatable anchors is contemplated as an alternative.
