<p>The invention pertains to the field of geophysical research using oil and gas wells, and can particularly be used for determining the profile of a well inflow and the parameters of a well-surrounding area (parameters of the perforation area, pollution parameters of the bottom area) et al. The method comprises modifying the flow rate of the well, measuring over time the temperature of the fluid flowing into the well for each layer, determining the amount of temperaturechange ?T p during the initial step and the magnitude of the steady-state value A of the temperature logarithmic derivative relative to time for each layer. The value of the specific flow rate q of each layer is determined using the formula (I), and the part of the perforation channel length through which the fluid inflow for each layer is carried out is calculated using the formula (II). The method further comprise determining the flow rate Q of each layer of the well according to the formula Q = q · h, where h is the thickness of the layer, while the profile of the well inflow is determined as being the combined flow rates Q of all layers.</p> |
