Methods are described for determining respective representative values for the permeability and clogging of an oil well or the like in order to evaluate the production quality thereof. The method is essentially characterized in that it comprises: lowering an assembly comprising a flow meter, a pressure sensor and a controllable stopper into the well down to the oil-bearing strata, said assembly being lowered in such a way that the pressure sensor and the flow meter are located below said controllable stopper; periodically controlling the stopper to vary the cross-section of the well at the oil-bearing strata; measuring oil flow rate variations by means of the flow meter; measuring oil pressure variations by means of the pressure sensor; and deducing, from a comparison of said pressure and flow rate variations, representative values for the permeability and clogging of the well. |
