摘要： The downhole tool disclosed herein comprises a body, a flexible member attached to the body, and a transducer housed in the body. The flexible member compresses against one side of the wellbore and urges the body against the other side. The transducer emits a signal to the flexible member reflectable from the flexible member back to the transducer. The signal travel time from the transducer to the flexible member and back is analyzed for estimating the distance between the body and the flexible member. The standoff distance can be estimated from the distance between the body and the flexible member. From the standoff distance, the wellbore diameter is estimated. The tool may also obtain wellbore dimensions by obtaining near side wellbore standoff and using a magnetic ruler to determine bowspring flexing. The magnetic ruler results may be used in conjunction with or without the far side standoff data.
摘要翻译： 本文公开的井下工具包括主体，附接到主体的柔性构件和容纳在主体中的换能器。 柔性构件压靠在井眼的一侧，并将身体推向另一侧。 换能器向柔性构件发射信号，该柔性构件可从柔性构件反射回换能器。 分析从换能器到柔性构件和背面的信号行进时间，以估计主体和柔性构件之间的距离。 距离可以从身体和柔性构件之间的距离估计出来。 从对立距离估算井筒直径。 该工具还可以通过获得近侧井眼间隙并使用磁尺来确定弓形弹性弯曲来获得井眼尺寸。 磁标尺结果可以与或不与远侧对位数据一起使用。

摘要： A stop collar assembly used for axially securing and/or to resist axial sliding of a downhole tool device. The assembly provided on a housing of the downhole tool and includes a generally annular ring having an inner circumference beveled outward proximate to the ring edge. A clamp ring having a raised portion on its outer surface is disposed adjacent and substantially coaxial with the annular ring. Pushing the annular ring against the clamp ring compresses the clamp ring onto the housing to resist axial sliding of the annular ring.
