Product Introduction
Magnetic guidance system consists of four parts:
①Laptop: installed with guidance software
②Interface unit: to communicate with probe and fulfill operation in combination with laptop.
③Magnetic sources: surface coil or beacon, powered by AC supplies, generating magnetic field for tracking.
④BHA: consists of top/bottom centralizers, wet connect, probe, spacer bar and stinger.
Steering Tool(probe)
The Steering Tool provides accurate survey information via state-of-the-art magnetometer and G-sensor, meanwhile, acts as a receiver for multiple magnetic sources, including AC guide wire and beacon tracking system. It is field proven with high durability, stability and reliability.
Beacon Tracking System(BTS)
The system is consisted of a beacon and a power source, used to verify the position of underground steering tool. The vertical suspension design makes it easy for setup and brings high accuracy. The internal battery is light and reliable, which makes the beacon access to restricted area. It ranges from mini size, standard to large beacon. The maximum survey range is up to 180m. BTS’s optional remote kit enables rapid drone surveys.
| Standard Beacon | |
| Size | Φ10x132cm |
| Weight | 22.5Kg |
| Power | 38Watt |
| Range | 100m |
| Accuracy(<40m) | +/- 0.5% |
| Accuracy（40-100m） | +/- 1.5% |
Beacon Signal Power Supply
This unit powers the magnetic target to generate alternating magnetic signals. Designed for harsh field conditions, it features a ruggedized engineering enclosure with triple-proof protection and potted circuit boards for durability and low failure rates. The built-in 12V lithium battery supports 30+ positioning cycles per charge. An optional 24V external battery can be connected for extended range and accuracy. Upgradeable with a remote control kit for wireless operation. Backed by a 3-year warranty.
BTS wireless remote control(WRC)
The BTS offers an optional wireless remote control kit for beacon operation. This add-on enables remote control, while manual control remains possible without it. The kit streamlines the beacon measurement process and is mandatory for drone-assisted beacon positioning. The wireless remote control kit consists of a beacon power supply with a wireless module and a remote controller, forming a wireless network. The controller’s start/stop buttons allow remote operation of the beacon, with real-time status data (voltage, current, operation status, duration, etc.) displayed on its screen. It also supports software-based control via computer connection.
Guide Wire Tracking
The guide wire tracking system is available in AC and DC modes, and the surface loop is varied in large coil (P2) with full coverage of centerline, small coil (APS), and circular mini-coil. Multiple turns can be applied in coil layout to increase the magnetic field strength. With high-resolution probe and AC power supplies, the maximum surveying depth of the large coil is up to 300m.
AC power supplies is especially used for guide wire tracking, with a maximum output current of 12.5 Amps, featured in easy operation. The power supply adaptively adjust the voltage according to the load after setting the output current value.
PWD
PWD (Pressure While Drilling) consists of a pressure module and a fixed sub. It contains two pressure sensors measuring internal pipe pressure and annular pressure, respectively. The sensors indirectly contact drilling fluid to obtain readings, which are transmitted to the surface in real time. Surface steering software displays live data, enables high/low-pressure alarms for kick risk warning, and calculates mud density and weight-on-bit based on annular pressure.
| Pressure Module | |
| Size | Ф44.5 x 1300mm |
| Weight | 10.5Kg |
| Annular Pressure Range | 0-6Mpa |
| Pipe Pressure Range | 0-25Mpa |
| Accuracy | +/- 0.1%（Max Range） |
| Non-magnetic Fixed Sub | |
| Size | Made-to-specification |
| Thread Type | Made-to-specification |
Gyro Module
Intersect Tracking System
Adding an AC electromagnetic transmitter module on one side makes the intersection and tracking to the probe on the other side available. Target tool can be accurately positioned and intersected within a range of 40m. The transmitter module is compatible with ParaTrack steering tool and APS probe. Rotating Magnet Ranging System is available from Smartdrill, and RM sub with various magnetic moment can be customized.
Advantages:
⚫ Compared to RMRS, it is independent of limitations from drill bit RPM and position. Better performance when drilling in soft formation without mud motor.
⚫ Intersection can be done at horizontal and curve sections.
⚫ Transmitter module can be installed at BHA at either side. Wells can be shifted whenever required.
⚫ Only one HDD rig can be used to do intersect under emergent condition.
