In oil well logging operations, the accuracy of depth and time data is directly critical to the success of geological interpretation. Whether in wireline logging or perforating operations, even the slightest depth error or time desynchronization can lead to misjudgment of hydrocarbon zones, resulting in substantial economic losses. As a professional manufacturer of oil logging tools, we proudly introduce our all-new Depth Time Recorder (DTR). Featuring advanced time-depth synchronization technology, the DTR records cable depth, tension, velocity, and timestamps to precisely map operational trajectories, helping you reconstruct the "invisible subsurface world." This solution is designed to provide high-reliability, high-precision data acquisition and time-base synchronization for logging operations.
Our Depth Time Recorder
Core Functions & Technical Advantages
◆ Multi-dimensional Real-time Data Acquisition
Comprehensive Monitoring – Records not only depth but also displays tension, line speed, and time in real-time, providing full traceability for every pulling and injection operation at the wellhead, eliminating blind operations.
Multi-channel Analog Inputs – Supports external sensors for measuring tension, pressure, temperature, flow rate, and other parameters. Unifies all sensor data under a single timestamp to build a complete production data chain.
◆ High-precision Time Synchronization
Internal Real-time Clock – Built-in high-precision clock ensures timestamp errors remain within milliseconds, resolving the "time drift" issues of conventional logging and providing a scientific basis for subsequent data correlation.
Precision Measurement – Utilizes digital encoder technology to calculate depth through rotation speed and line velocity, avoiding cumulative errors caused by mechanical wear. Measurement accuracy far exceeds traditional mechanical measuring tapes.
Applications & Industry Value
The Depth Time Recorder is widely applied across all stages of logging operations, serving as an essential tool for ensuring operational quality:
◆ Drilling Operation Monitoring–Real-time recording of drilling depth and rate of penetration (ROP) assists in analyzing drilling parameters and prevents wellbore collapse and drill bit sticking.
◆ Production Management–During water injection or oil pumping operations, records the stroke and extraction depth of pumpjacks to calculate oil production or water injection volumes, serving as a basis for metering and accounting.
◆ Emergency Response–Records wellhead tension variations to monitor anomalies and provide early warnings of blowout events, safeguarding operational safety.
◆ Open-hole Logging–Provides precise depth control for natural gamma, resistivity, and other well logs.
◆ Perforating Operations – Accurately records detonator firing time and depth for perforation positioning accuracy analysis and incident investigation.
◆ Production Logging–In multiphase flow logging, calculates fluid velocity and production profiles through precise time-depth relationships.
Application Scenarios & Trust Building
In an ultra-deep well logging project at 7,800m, our Depth Time Recorder integrated with a downhole multi-parameter logging tool, successfully achieved continuous data acquisition across three drilling runs. By performing high-precision matching between surface-recorded time-depth data and downhole-recorded GR-resistivity-time data (with a matching point time error of less than 0.1 seconds), the final composite logging curves achieved a depth error of only 0.08 meters, providing critical data support for the client to accurately identify thin hydrocarbon zones (thickness of 0.5 meters).
During offshore platform perforating operations, real-time monitoring of cable tension and running depth enabled clear identification of the "slack-off-pick-up" null signature on the tension curve when the perforating guns reached the target zone. This assisted operators in controlling perforating depth error within ±0.05m, preventing misfire incidents.
Conclusion of Depth Time Recorde
The Depth Time Recorder serves as the "Spacetime Anchor" in logging engineering. It does not directly indicate formation oil-bearing properties, yet its precision determines whether all the costly data acquired by downhole instruments holds value. From photoelectric encoder pulse counting to standardized data file output, we adhere to the standards of data traceability, verifiable accuracy, and protocol compatibility, providing global clients with a trusted depth positioning reference.
