    • An apparatus and method for substantially sealing an opening defined by a hydrocarbon well downhole component, wherein an interior portion of the downhole component is in fluid communication with a formation surrounding the hydrocarbon well. The apparatus includes a deformable plug adaptable to being injected into the wellbore upstream of the opening and carried through the wellbore in a fluid. The fluid carrying the deformable plug can flow through the opening and the deformable plug is sized and configured such that at least a portion of the deformable plug can deform to the contour of the opening and seat in the opening. The deformable plug is capable of swelling, hardening, or compressing such that the deformable plug forms a substantially sealed relationship with the hydrocarbon well downhole component such that the interior portion of the downhole component ceases to be in fluid communication with the formation surrounding the well.
    • 一种用于基本上密封由烃井井下部件限定的开口的装置和方法,其中所述井下部件的内部部分与围绕所述烃井的地层流体连通。 该装置包括可变形插塞,适于在开口的上游注入井眼并以流体的形式穿过井眼。 承载可变形插塞的流体可以流过开口,并且可变形插塞的尺寸和构造使得可变形插塞的至少一部分可以变形成开口和座位在开口中的轮廓。 可变形插塞能够膨胀,硬化或压缩,使得可变形插塞与烃井井下部件形成基本密封的关系,使得井下部件的内部部分不再与围绕井的地层流体连通。

    • A permanent magnet brushless (PMBL) servo motor test apparatus and method allow testing of a motor in place. A set of static and dynamic tests is performed to determine proper motor operation of armature windings and rotor feedback devices. The test system of the present invention displaces the motor drive system. The test system comprises an armature driver, a feedback device input, and a system controller. The armature windings of the motor-under-test are driven in a polarity sequence according to a test sequence, whereby the rotor is driven in a series of rotations. Angle feedback is tested at a plurality of said rotations. Rotor velocity outputs are tested during said rotations. Armature current and voltage are determined at a plurality of said rotations and winding balance is tested. Said power switch is also operative to apply a voltage between the armature windings and the motor case to test for fault current flow.In another embodiment of the invention, motor identification is decoded by the system into motor configuration and motor operation parameters, necessary to test the motor. Motor identification may be entered by an operator or captured from machine readable tags such as a barcode tag or an RFID tag.
