FIELD: oil production industry. SUBSTANCE: according to method, run into well by rope or scraper wire down to depth below level of degassing is turbine-type flow rate sensor with converter of rotation speed into code-pulse signals which are recorded according to program preset by timer. Electronic memory and timer are located in subsurface flow rate sensor. Results of recorded code-pulse signals are decoded and processed with the help of computer after lifting of flow rate sensor from well by means of catching device. EFFECT: high efficiency.
