Quantity: 1set Payment Method: T/T, L/C, Credit Card, Western Union, Cash Overview The Gamma is used to measure the natural radioactive strength in formation in engineering logging, which detects gamma photon, and changes to low-power photon by use of NaI. The photomultiplier tube detects the low-power photons and converts them into electrical signal, the logging curves can be used to detect and evaluate the radioactive deposit by circuit measurement, to verify the sandstone formation and estimate the shale content, to reflect the permeability of dirty formation. The gamma well temperature instrument can be connected to other logging tools for combination logging, which is used for formation comparison and depth calibration of all logging curves. When it is applied in cased hole, its output logging curves can be used to compare with open hole data, which could secure the accuracy of perforation depth. The gamma well temperature measurement adopts high-accuracy platinum temperature sensors, and obtain well temperature by measurement of circuit conversion and enlargement. Specification Total length 1480mm Free length 1479mm Zero length 1069mm OD 70mm Temperature range -30℃～175℃ Max use pressure 100MPa Voltage 90V DC Current 20±5mA Gamma measuring range 20000cps Well temperature measuring range -25℃～175℃ Well temperature measuring accuracy ±1℃ Well temperature measuring resolution 0.003℃ |
