METHOD OF AUTOMATED GEOLOGICAL SURVEY OF WELLS AND SYSTEM FOR ITS IMPLEMENTATION Russian patent published in 2020 - IPC E21B47/22 

FIELD: drilling of directed wells.

SUBSTANCE: in particular, disclosed is a method of computer-aided simulation of an automated process of geological survey of wells, comprising steps of: obtaining primary parameters of the developed well, containing at least logging data and inclination data; selecting, at least, one support well based on automated analysis of cross-right correlation; obtaining parameters of at least one selected support well, containing at least logging data and inclination data; performing construction of primary geostationary model based on data of at least one reference well; said geonavigation model is tuned using structural surfaces, wherein the primary model comprises a set of logging curves and inclination measurements; determining the synthetic curve based on the logging curve from the primary geonavigation model; obtaining real drilling data of actual well; determining well shaft position based on comparison of synthetic curve with logging curve based on data obtained from well drilling data; Drilling recommendations for drill intervals are made on zenith angle variation. System for realising this method is also provided.

EFFECT: technical result is higher accuracy of determining well bore position during drilling.
