摘要： A well penetrator consists of a number of hydraulic fluid control components and a carriage carrying a hydraulic motor and a mill bit supported in a housing which is moveable down a well casing. The control components cause the carriage carrying the mill bit to be indexed up a predetermined distance relative to the well casing and then extended gradually into contact with the well casing while being rotated by the hydraulic motor. After the mill bit completes a hole through the well casing, the hydraulic components index the mill bit back down to its starting position and align a nozzle on the outer end of a high pressure lance with the opening in the casing to direct fluid from the nozzle as the lance is moved outwardly through the hole in the casing drilled by the mill bit.

摘要： A system and methods for improving the vertical resolution of NMR logs based on data acquisition methods and signal processing techniques that need not apply Phase Alternated Pair Stacking (PAPS). The method is based on reducing the level of coherent non-formation signals, by estimating these signals and removing the estimates from the underlying NMR pulse echo trains. Once the estimated non-formation signal components have been removed, standard NMR processing methods are applied to derive petrophysical properties of the formation being investigated. In a preferred embodiment the NOPAPS method of this invention is practiced along with a data acquisition sequence, which can be used to further increase the logging speed of the tool or vertical resolution of the measurements.
摘要翻译：基于数据采集方法和信号处理技术，不需要采用相位交替堆叠（PAPS），提高核磁共振测井垂直分辨率的系统和方法。该方法基于通过估计这些信号并从基础NMR脉冲回波列除去估计值来降低相干非形成信号的水平。一旦已经去除了估计的非形成信号分量，则应用标准NMR处理方法来导出正在研究的地层的岩石物理性质。在优选实施例中，本发明的NOPAPS方法与数据获取序列一起被实施，数据采集序列可用于进一步增加工具的记录速度或测量的垂直分辨率。
