摘要： Sonic data, ultrasonic data, density data, cased-hole neutron data, and open-hole neutron data of the wellbore are obtained. The sonic and ultrasonic data provides the amplitude, frequency, and phase of the altered sonic and ultrasonic waves. The far counts, near counts, and energy spectrum are obtained from density data, cased-hole (CH) neutron data, and open-hole (OH) neutron data. The amplitude, frequency, and phase provide the interface densities of the first, second, and third interfaces. The hydrogen index (HI) of the formation and the cased wellbore are obtained from the CH and OH neutron data. The widths of the second and third interfaces are obtained from the HI's and the densities of the second and third interfaces.

摘要： Acoustic measurements are obtained and combined with some identification of regions that are expected or believed to be cemented. Based at least in part on this information, a processing unit derives an annular material classifier that can identify those measurements characteristic of the cemented regions (including regions cemented with a resin cement formulation), and that further applies the classifier to the measurements to generate a cement log that can be displayed to a user. Cross-plots of waveform amplitude, acoustic impedance, and the derivative of acoustic impedance, have revealed that resin cement, for example, has characteristic acoustic properties that form a small cluster within the range of expected measurements. For improved identification reliability, such clusters can be identified adaptively.
摘要翻译：获得声学测量，并结合预期或相信粘结的区域的一些识别。至少部分地基于该信息，处理单元导出环形材料分类器，其可以识别胶结区域（包括用树脂水泥配方粘合的区域）的特征的那些测量，并且进一步将分类器应用于测量以产生水泥日志可以显示给用户。波形幅度，声阻抗和声阻抗的导数的交叉图表明，例如，树脂水泥具有在预期测量范围内形成小簇的特征声学特性。为了提高识别可靠性，可以自适应地识别这样的簇。

摘要： An acoustic imaging tool, logging system and method are disclosed for producing high-resolution three-dimensional images. The imaging tool may include three separate arrangements of acoustic transducers: a circumferential set for wall inspection, internal transducers for fluid characterization within a chamber open to wellbore fluid, and forward-looking transducers located at the bottom end of the tool. Forward-looking transducers emit ultrasonic waves and receive reflections back when solid features are located under the tool. In some embodiments, Doppler effect calculations may be performed to produce forward-looking acoustic images. In other embodiments, an ambient acoustic energy illuminates the wellbore, and an acoustic lens set focuses reflected ultrasonic waves onto an acoustic imaging array of an ultrasonic camera.

摘要： Sonic data, ultrasonic data, and density data of the annulus are obtained using a sonic tool, an ultrasonic tool, and a density tool, respectively, included in a tool string. A first deconvolution operation is performed to obtain an amplitude, a frequency, and a phase of the modified sonic wave. A first inverse modeling operation results in a first density value of the annular media. A second deconvolution operation is performed to obtain an amplitude, a frequency, and a phase of the modified ultrasonic wave. A second inverse modeling operation results in a second density value of the annular media. A third deconvolution operation is performed to obtain far counts, near counts, and an energy spectrum of gamma rays. A third inverse modeling operation results in a third density value of the annular media.
