In the measurement process of oil and gas wells, taking into account the requirements of well depth measurement accuracy, a high accuracy oil and gas well depth measurement system based on photoelectric encoder is proposed and its principle is introduced. Describe the characteristics of jitter interference signal of optical encoder, and give the circuit with high accuracy anti-jitter and its working principle. Analyze the reason of the error and give the error compensation method. Using LabVIEW software to write an intuitive and efficient PC display interface. Depth is an extremely important measurement parameter in well logging operations. Its accuracy and reliability have an important impact on the measurement results and the subsequent operation of oil and gas wells. In modern underground survey (such as testing, find water, etc.), can time and accurately get the underground data
