METHOD AND COMPUTER SYSTEM FOR CONTROL OF DRILLING OF THE WELLS Russian patent published in 2020 - IPC E21B44/00 G06F30/20 

FIELD: soil or rock drilling.

SUBSTANCE: invention relates to drilling wells in productive formations. In accordance with disclosed method, initial data characterizing drilling process and containing real-time data, measured during well drilling, are selected, contextual drilling data related to drilling macro-parameters, and geological data characterizing productive formation, in which drilling is performed. Collected data is computer processed and structured data arrays containing complete characteristic of drilling process at each moment of time are formed. Using structured data arrays as input data, actual conditions of drilling are determined in real time and probability of occurrence of complications during drilling is predicted. Using input data determined in real time actual conditions of drilling and probability of occurrence of complications during drilling, recommendations are made on correction of trajectory of well shaft for obtaining maximum productivity of well and / or recommendations on change of drilling modes, composition of drilling mud. Computer system for controlling well drilling in accordance with the present invention comprises a drilling data collection unit, a computer unit for collecting collected data, a real-time analytics unit and a real-time recommendation generation unit.

EFFECT: technical result consists in creation of effective and high-speed control system of wells drilling, providing accident-free well cabling under varying conditions and maximum extraction of hydrocarbons.
