Sentence examples for reflection log from inspiring English sources
Seismic facies in this research was carried out adopting the Prather et al. 1998 type convention (Figs. 2, 3) and uniquely classifying them from our seismic reflection, log motifs and sand percentage interpretation.
The master node is the main control circuit of the tool for azimuthal acoustic reflection logging.
The combined arc arrays of the proposed 3D acoustic transmitter stations are also consistent, which indicates that the system can be used in azimuthal acoustic reflection logging.
Each of the four third-level subarrays in the same circumferential direction display consistent horizontal and vertical directivities, thus satisfying the requirements of azimuthal acoustic reflection logging.
In this study, we use seismic reflection, logging and core data to investigate the depositional systems and their controlling factors in the lower Triassic in the northwestern margin of Junggar basin.
The data included mentors' written reflections, log books, and a brief demographic survey.
This pulse radiation mode can typically be used in azimuthal acoustic reflection logging tools.
Therefore, azimuthal acoustic reflection logging can be realized with the proposed transmitter stations.
Acoustic reflection logging generally facilitates more in-depth investigation than conventional acoustic logging, and it also yields images with higher resolution than those obtained through seismic exploration.
The acoustic waves reflected by the near-borehole interfaces with non-continuous acoustic impedance are obtained through acoustic reflection logging (Hornby 1989; Ellis et al. 1996; Esmersoy et al. 1997, 1998; Chang et al. 1998; Yamamoto et al. 1998; 1999).
When acoustic energy is radiated to the formations around a borehole during azimuthal acoustic reflection logging, the vertical deflection angle of the main acoustic beam radiated by the transmitter is generally smaller than the first critical angle of the incident acoustic wave on the borehole wall from the borehole fluid.
