Introductions
MMRO Gyro Inclinometer uses the new technology solid-state gyroscope and MEMS accelerometer, and it is a single and multi-point inclinometer with north seeking. Real-time measurement of GT and EHR, Offers real-time data transmission via mud pulse telemetry or wired telemetry. Enables surface personnel to monitor and analyze downhole data instantaneously, facilitating timely adjustments and optimizing drilling operations.
L140 MMRO Solid State lnclinometer targets oil & gas wells (deep wells, high pressure/temperature)
L140M & L140R MMRO Solid State lnclinometer targets mining and geological boreholes, it was designed for magneticinterference environments such as mine shafts (near steel casing, rails or magnetic strata) where magnetic survey tools lose accuracy, making it ideal for underground mining borehole orientation work.
L100 CGRO Continuous Gyro Inclinometer is a new type of continuous gyro inclinometer for drilling engineering, directional drilling and borehole trajectory measurement, used in the oil and gas industry, mainly to measure the inclination and azimuth of downhole drilling tools, there by helping to determine the accurate direction and position of drilling.
Applications
- Drilling engineering, directional drilling and borehole trajectory measurement
- Wellbore trajectory measurement, used to record well history inclinometry data and borehole trajectory remeasurement in casing;Offshore drilling platform cluster well orientation, used for trajectory measurement and directional measurement in magnetic interference environments such as adjacent wells
- Diagonal orienteering, used for old well side tracking
- Directional perforation for oil production engineering
- Cluster (multi-well pad) orientation surveys in mining fields
- Mine-shaft casing-window orientation (side tracking from existingcasing)
- Directional surveys in mine development and exploration boreholes
- Surface-readout surveys for immediate data review at the mine site
- Operations in magnetic-interference mine environments where magnetic tools fail
