摘要： A downhole steering tool is disclosed. The steering tool includes a rotatable shaft, a substantially non-rotating tool body deployed about the shaft, and a plurality of force application members deployed on the steering tool body. The steering tool further includes a bendable section deployed in the steering tool body. The bendable section is disposed to bend preferentially relative to the steering tool body under an applied bending load. The use of a steering tool body having a bendable section tends to advantageously reduce bending stresses in the steering tool body during use. Moreover, tools embodying this invention may be suitable for higher dogleg severity applications.
摘要翻译：公开了井下转向工具。所述转向工具包括可旋转的轴，围绕所述轴布置的基本不旋转的工具主体以及部署在所述转向工具主体上的多个施力部件。所述转向工具还包括设置在所述转向工具主体中的可弯曲部分。可弯曲部分设置成在施加的弯曲载荷下相对于转向工具主体优先弯曲。使用具有可弯曲部分的转向工具主体倾向于有利地减少在使用期间转向工具主体中的弯曲应力。此外，体现本发明的工具可适用于较高的狗腿严重性应用。

摘要： A formation fluid sampling tool is provided. The formation fluid sampling tool includes at least one sample tank mounted in a tool collar. The tool collar includes a through bore and is disposed to be operatively coupled with a drill string such that each sample tank may receive a correspondingly preselected formation fluid sample without removing the drill string from a well bore. At least one of the sample tanks further includes an internal fluid separator movably disposed therein. The separator separates a sample chamber from a pressure balancing chamber in the sample tank. The pressure balancing chamber is disposed to be in fluid communication with drilling fluid exterior thereto. The sampling tool further includes a sample inlet port connected to the sample chamber by an inlet passageway. A method is also provided for acquiring a formation fluid sample from a formation of interest.
摘要翻译：提供地层流体取样工具。地层流体采样工具包括安装在工具环中的至少一个样品罐。工具套环包括通孔，并且设置成与钻柱可操作地联接，使得每个样品罐可以接收相应地预选的地层流体样品而不从井眼移除钻柱。至少一个样品罐还包括可移动地设置在其中的内部流体分离器。分离器将样品室与样品箱中的压力平衡室分开。压力平衡室设置成与其外部的钻井液体流体连通。采样工具还包括通过入口通道连接到样品室的样品入口。还提供了用于从感兴趣的形成中获取地层流体样品的方法。

摘要： A steering tool for use in a well bore is disclosed. The tool includes at least one extendable and retractable blade deployed thereon. The blade is elastically spring biased radially inwards towards the tool such that upon removal of an actuating force, the blade retracts. In exemplary embodiments, the blade includes at least one spring-like, elastically deformable member disposed to elastically spring bias the blade. The spring-like member may include first and second elongated leg portions located on opposing sides of a sprung hairpin portion. Tools embodying this invention may be advantageous for small diameter applications.
摘要翻译：公开了一种用于井眼的转向工具。该工具包括在其上部署的至少一个可伸缩刀片。刀片被弹性弹簧偏压向工具偏置，使得当移除致动力时，刀片缩回。在示例性实施例中，刀片包括设置成弹性地偏置刀片的至少一个类似弹性的弹性变形构件。弹簧状构件可以包括位于弹簧发夹部分的相对侧上的第一和第二细长腿部。实施本发明的工具对于小直径应用可能是有利的。
