OrWell 120 – Digital Well Orientation String / Mess-Stab für Bohrung

Messgerät für Bohrlöcher bzw Bohrlochorientierung Digital Borehole Orientation logging string is designed to give accurate information about orientation of the well: Azimuth (Heading), Inclination (Pitch) and Relative Bearing (Roll). It can be utilized in Open Hole and (metal or plastic) Cased Hole environment using monoconductor cable. The OrWell 120 is continuous north seeking type of tool and measuring could be performed in vertical or horizontal well with appropriate equipment (centralizers, tractors, coil-tubing, semi-rigid cable). The full system includes the downhole tool string and our Acquisition System WellScan LS730 with software for data management, analysis and presentation of collected data. The string itself is fully compatible with SDS Warrior Acquisition System. Technical Data: String Diameter: 1-11/16 in (43 mm) String Length: 10.2 ft (3,1 m) Max. Pressure: 15,000 psi (103,4 MPa; 1034 bar) Max. Temperature: 250°F (120°C) Detector for Azimuth in Open Hole: 3-axis magnetometer Detector for Azimuth in Cased Hole: 3-axis gyroscope Detector for Inclination and Relative Bearing: 3-axis accelerometer Azimuth Angular Range / Resolution / Accuracy: 0° - 360° / 0.1° / ± 0.1° Inclination Angular Range / Resolution / Accuracy: 0° - 90° / 0.1° / ± 0.1° Relative Bearing Angular Range / Resolution: 0° - 360° / 0.1° Gyroscope Accuracy: ± 1.0° Repeatability: ± 0.5°
