Abstract | A new fast method of solving the inverse problem of multiprobe electrometry of wells is proposed. It allows one to account for the quantitative contribution of measuring each probe to the final result. The algorithm for solving the inverse problem has been developed and implemented in a software. It is shown that the proposed approach can also significantly improve the vertical resolution of the method as a whole. An example of the comparison of various results of solving the inverse problem of lateral logging sounding and lateral logging, when changing the contribution of the measurement of each probe to the final result, is given. It is concluded that the use of a quick method for solving the minimization of the residual functional, if combined with the ability to consider the contribution of each probe of the multiprobe electrometric complex to the final result of solving the inverse problem, makes it possible to increase the accuracy of a quantitative interpretation. It is also shown how the developed algorithm and the corresponding created software make it possible to increase the accuracy of determining the geoelectric parameters of oil and gas reservoirs. The results of the work were introduced into the production at a number of commercial geophysical organizations. |
