YSS-45G is designed to meet the high temperature oil well measurement in a special zone. Based on YSS-25 mode inclinometer, it is added with a heat shield tube resistant to a high temperature, and can work for 7 hours in 150? and 2 hours in 260? environments. This instrument applies all the features
YSS-25 is the thinnest in outer diameter of probe for YSS series electronic single and multi-shot survey system. Besides that it has all the features of YSS-32 type, it is particularly suitable to measurement of the locus of small diameter wells.
The positive pulse system with minimum moving parts extends downhole life, simplifies maintenance and offers low resistance to flow ranges from 10 to 55l/s.
