By measuring the mud flow rate based on a cable-less leak measuring instrument during drilling, the mud temperature is determined by two parameters, the location of the leak zone. The measurement scheme of measuring the position of the leakage layer with the instrument is put forward: the mud flow velocity and the temperature are measured digitally according to the pre-selected sampling period and sampling times, and the measured data are stored in the underground instrument’s internal memory according to a certain format , Read the data from the computer, and the measured data is transferred to the disk to form a data file; according to the prepared processing system software for data visualization (graph or tabular form) to determine the location of the drain layer. The temperature, flow rate sensor, signal processing circuit and data acquisition and storage circuit of downhole instrument are designed.
