摘要： A stabilizer assembly is at least 12′ long and preferably at least 14′ long and is used to drill a straight bore hole in the earth. A central passage through the assembly closely follows a centerline as may be determined by measuring the wall thickness of the tube at a variety of locations in a single plane. At least three stabilizing sections are integral with the tube and include alternating ribs and flutes. Hardbanding on the ribs is ground down to tolerances with a grinding machine or face plate lathe having centers sufficient to receive the 12′ long stabilizer assembly.
摘要翻译：稳定器组件至少12'长，优选至少14'长，用于在地球上钻一个直孔。通过组件的中心通道紧密地遵循中心线，这可以通过在单个平面中的各种位置处测量管的壁厚来确定。至少三个稳定部分与管是一体的，并且包括交替的肋和槽纹。使用研磨机或面板车床将肋骨上的耐磨带磨碎成具有足以容纳12'长的稳定器组件的中心的公差。

摘要： A well tool includes a whipstock in conjunction with an inflatable packer for use in the open hole. A pivotal joint between the whipstock and packer allows the whipstock to pivot relative to the packer and springs bias the whipstock into an angled relation relative to the packer. A setting tool connects the whipstock and packer in a rigid straight line position while the tool is being run into the hole. Drilling fluid can be circulated through the tool. When the packer is set and the setting tool is removed, the whipstock pivots relative to the packer against the side of the open hole. This allows the hole to be sidetracked from the low side of the hole.
