摘要： A sample of material is rotated within a pair of parallel, spaced-apart laser beams. Variations in the diameter of the sample are determined with azimuth from the amounts of the laser beams intercepted by the sample as it rotates about an axis perpendicular to the plane of the laser beams. The sample is translated along this axis within the path of the laser beams so that the diameter of the sample is determined for a plurality of spaced-apart planes through the sample perpendicular to the axis of rotation. The deformation of the material with stress is determined by measuring the variations in diameter of the sample as the stress on the sample is changed.

摘要： A method and apparatus to determine in-situ "creep" displacement in a cored or drilled borehole. A borehole creep displacement (BCD) tool is suspended into the borehole via a wireline logging cable. Gaging piston fluid forces gaging pistons in a mechanical/electrical assembly of said tool to extend and contact the borehole wall which causes gaging pressure to build. Upon reaching a predetermined pressure, excess fluid flows into a micro-motion fluid distribution body and into an actuator assembly causing an accumulator linear variable displacement transformer (ALVDT) to move thereby causing electrical signals to be transmitted to surface equipment. Once the LVDT has been displaced fully, a closed fluid system within the gaging pistons and a micro-motion assembly is created. Thereafter, any movement of the gaging pistons by the borehole wall will cause fluid motion of a micro-motion cylinder which is attached to a micro-motion LVDT. Movement of the micro-motion LVDT can be read as displacement in thousandths of an inch or as a direct mechanical gain for estimating electrical values.
摘要翻译：确定岩芯或钻孔中原位“蠕变”位移的方法和装置。钻孔蠕变位移（BCD）工具通过电缆测井电缆悬挂在钻孔中。测量活塞流体力在所述工具的机械/电气组件中测量活塞以延伸和接触钻孔壁，这导致测量压力建立。在达到预定压力时，多余的流体流入微运动流体分配体并进入致动器组件，导致蓄能器线性可变位移变压器（ALVDT）移动，从而使电信号传递到地面设备。一旦LVDT已经完全移动，就会产生一个封闭的流量系统，在测量活塞和微运动组件内。此后，井壁上的测量活塞的任何运动将导致连接到微动LVDT的微运动气缸的流体运动。微动LVDT的运动可以读取为千分之一英寸的位移或用作估计电气值的直接机械增益。
