[0002] The oil directional instrument is an important equipment in the field of oil exploration. Its main function is to determine the direction, distribution and reserves of underground oil. The gamma probe is a measuring device based on the principle of radioactivity. It has the characteristics of high precision and high sensitivity, and can detect the distribution of underground oil more accurately. The gamma data storage method of the existing directional instrument is that the gamma probe sends the signal to the directional probe, and the directional probe stores it. The gamma data cannot be stored separately inside the gamma probe. However, in actual work, faults always occur, resulting in the loss of gamma data in the directional probe, and the directional instrument fault cannot be judged. Therefore, there is a need for a system that can be installed inside the gamma probe and store gamma data separately underground to help the directional instrument perform fault and gamma data analysis, prevent the loss of gamma index, and improve data acquisition accuracy.

The control device is used to start counting gamma photons when receiving the test instruction sent by the host computer, and at the same time receive the temperature information collected by the temperature sensor, and send the counting information to the host computer for visual display. However, due to the lack of storage function, failures always occur in actual work, resulting in the loss of gamma data.
