The high -temperature orientation sensor is a popular product in energy drilling industries. For a long time, high -precision measurement at 175 ° C environment in the drilling well is a technical problem that cannot be ignored. In recent years, the 175 ° C high -temperature orientation sensor represented by the DS750 series has been in the energy drill. During the work, it showed its skills.
What is Well drilling?
Well logging, also known as borehole logging is the practice of making a detailed record (a well log) of the geologic formations penetrated by a borehole. The log may be based either on visual inspection of samples brought to the surface (geological logs) or on physical measurements made by instruments lowered into the hole (geophysical logs). Some types of geophysical well logs can be done during any phase of a well's history: drilling, completing, producing, or abandoning. Well logging is performed in boreholes drilled for the oil and gas, groundwater, mineral and geothermal exploration, as well as part of environmental and geotechnical studies.
The high -temperature orientation sensor with the drilling well should have high temperature resistance, high vibration resistance, high accuracy, and high reliability abilities. The DS750 high-temperature orientation sensor contains 3 axis magnetometer and 3 axis accelerometer, which can maintain a long stable work in the 175℃ drilling environment. The angle of the inclination and gravity tools is measured by the 3 -axis accelerometer. After measure the inclination and toolface angles, three -axis magnetic flux-gate measures the azimuth angle of the sensor. The measurement accuracy of the toolface and the inclination angle is ± 0.1 °, and the accuracy of the azimuth angle measurement is ± 0.3 °. In addition, the high -temperature orientation sensor at 175 ° C environment can also measure the total acceleration, total magnetic field strength, magnetic tool surface angle, geomagnetic inclination angle, and temperature. Today, the DS750 high -temperature orientation sensor has been widely used in the drilling wells of oil and gas field exploration and exports to more than 30 countries in the world.
