Acoustic logging is an advanced geophysical well-logging technique that uses sound wave propagation characteristics to evaluate subsurface formations, porosity, and structural integrity. By transmitting acoustic pulses into the formation and measuring the travel time, amplitude, and attenuation of the sound waves, this technology provides engineers with precise data to assess reservoir quality during drilling, completion, and production operations.
Modern acoustic logging tools integrate multi-pole acoustic sources, array receivers, and high-performance signal processing algorithms. This enables the detection and analysis of compressional, shear, and Stoneley waves, allowing accurate fracture identification, lithology analysis, stress evaluation, and borehole stability monitoring.
Compared with conventional logging techniques, acoustic logging offers several significant advantages:
High precision and resolution – Detects subtle formation variations and identifies reservoir characteristics with accuracy.
Real-time data acquisition – Supports on-site data analysis and AI-assisted signal interpretation for faster decision-making.
Multi-parameter evaluation – Provides comprehensive formation assessment using wave velocity, attenuation, and frequency spectrum analysis.
Wide applicability – Extensively used in oil and gas exploration, geothermal development, CO₂ sequestration, and underground energy storage.
With the advancement of AI-driven signal processing and acoustic imaging, acoustic logging is evolving toward intelligent and automated solutions. The integration of machine learning and acoustic inversion algorithms enables next-generation systems to deliver more accurate geological modeling and reservoir prediction, driving greater efficiency and insight in the energy industry.
RK1000B Duplex Cased Hole Logging Surface System consists of a data acquisition panel and a laptop. The system completes all casing well logging operations such as production logging, engineering logging and formation parameter logging by receiving the downhole duplex (or simplex or pulse) tool signals through the data acquisition case and cooperating with wellhead depth, tension and other tools.
It is a new type of array lateral logging tool with multiple investigation depths. One logging can provide one mud resistivity curve and five formation resistivity curves with different investigation depth.
It can use 2-D model and inversion technique to calculate the influence of wellbore, adjacent formation and invasion simultaneously, and then produce more accurate and perfect formation resistivity Rt.
The standard tool for imaging logging system with a unipolar source, 2 orthogonally distributed dipole sources in the circumferential direction and an 8×4 receiving array, which can realize the function of full waveform logging and direct acquisition of formation shear wave velocity.
After processing the acquired 96 acoustic waveforms by post- logging processing software, more accurate time differences of formation P-wave, shear wave and Stoneley wave can be obtained and formation anisotropy can be also obtained.
This instrument is a replacement for the HFWS full-waveform sonic logger of Hostile logging system (or LOGIQ-B logging system), which can digitally collect the signals of the full-waveform sonic waveforms in the sonic waveforms such as longitudinal waveforms, transverse waveforms, Rayleigh waveforms, and Stonley waveforms, and it can measure the longitudinal waveforms and the transverse waveforms and the Stonley waveforms of the stratigraphic longitudinal time difference.
It is capable of measuring the time difference of longitudinal wave, transverse wave and Stonley wave, and can carry out acoustic amplitude logging in cased wells to provide information on cement cement quality.
Two working modes: full wave train mode and cement cemented logging mode.
This instrument is the replacement of HDEL three-lateral logging instrument of Hostile logging system (or LOGIQ-B logging system), and it is one of the main methods of resistivity logging;
it can simultaneously provide two different depths of lateral resistivity measurements of intrusive zone (shallow lateral, abbreviated as LLS) and original formation (deep lateral, abbreviated as LLD), which, together with other logging data, can be used to delineate the permeable layer, judge the oil-water layer, determine and evaluate the oil-bearing properties of the formation intuitively and accurately.
The tool includes telemetry/CCL/GR combination tool, temperature and pressure combination tool, water holdup tool, continuous flowmeter, on-line flowmeter, full borehole flowmeter, tuning fork density tool etc.
The tool is specially designed for logging needs of ultra-high temperature and ultra-high-pressure wells. It adopts 200°C high temperature sensors, components and sealing rings, and is suitable for depth correction and production profile logging of ultra-deep wells and high geothermal gradient wells.
The fibre-optic logging system with independent intellectual property rights, relying on the civilian transplantation of military technology.

DAS-Distributed Fiber Optic Acoustic and Vibration Analyzer is a real-time, online, and continuous monitoring system based on coherent Rayleigh scattering and optical time-domain scattering principles.
It can realize precise detection, identification, and accurate localization of vibration events with multiple vibration time stamps.
DTS-Distributed Fiber Optic Temperature Sensing Analyzer is a real-time, online, and continuous monitoring system based on Raman scattering and optical time-domain scattering principles. It can realize precise detection, identification, and accurate localization of temperature.
The downhole crawler, also known as a horizontal well tractor or crawler, is a tool used to convey downhole equipment in horizontal and highly deviated wells.
During operations in such wells, when gravity alone is insufficient to move the downhole tools to the target section, the hydraulic crawler utilizes its own power system to transport the equipment to the desired well interval.
