Abstract
Summary A new fast inverse problem solving method of multi-probe electrometry of wells is proposed, which allows taking into account the quantitative contribution of measuring each probe to the final result. The algorithm for solving the inverse problem has been developed and implemented in software. It is shown that the proposed approach can also significantly improve the vertical resolution of the method as a whole. An example is given of comparing 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. It is concluded that the use of a quick method for solving the minimization of the residual functional combined with the ability to take into account the contribution of each probe of the multi-probe electrometric complex to the final result of solving the inverse problem makes it possible to increase the accuracy of quantitative interpretation. It is also shown how the developed algorithm and the corresponding software created make it possible to increase the accuracy of determining the geoelectric parameters of reservoirs. The results of the work were introduced into the production of a number of commercial geophysical organizations.
