FIELD: methods for estimating properties of underground formations. ^ SUBSTANCE: in accordance to method, electrical properties of formation are measured in drill well. Formation parameters model is developed. Position of distributed beds is determined. Measurements of electrical properties are modeled using certain positions of beds, assuming that one or more of aforementioned electrical properties are equal across whole extent of some of aforementioned distributed beds. Modeled measurements are compared to measured electric properties. Comparison results are used for optimization of position of beds and evaluating physical/oil-chemical properties of formation on basis of measured electric properties. Various measurements of electric properties of formation may be performed and evaluation of properties of formation on basis of results of these various measurements for realization of combined inversion. Complex model may be used, which includes electric properties in conjunction with other oil-physical information for evaluating properties of formation on basis of results of electrical measurements. ^ EFFECT: more precise determining of value of resistance Rt for evaluating formation characteristics. ^ 6 cl, 6 dwg |
