METHOD FOR WELL DRILLING CONTROL WITH AUTOMATED SYSTEM FOR REAL-TIME CONTROL OF WELLS DRILLING Russian patent published in 2019 - IPC E21B44/00 

FIELD: oil and gas industry.

SUBSTANCE: group of inventions relates to control of development of oil and gas deposits, including with a complex geological structure, methods of controlling well drilling during development of deposits. Method consists in the fact that initially, relying on a priori data, at least one well is drilled in the characteristic site of the development object, wherein the drilling trajectory and drilling parameters are selected directly during drilling of the well at given constraints, and drilling is performed until productive reservoir is achieved while providing criterion of maximum oil recovery in area of collector adjacent to well, wherein during drilling of the well, complete reliable identification of the parameters of the development object and the surrounding mining and geological rocks, based on the results of which at least one suboptimal model of the object is formed, taking into account of which drilling of other wells is performed also with achievement of criterion of maximum oil recovery and monitoring of the mining and geological environment adjacent to the well, based on the results of which the suboptimal model of the object development is promptly corrected, and this iterative process is continued until achievement of optimum model of development of object and deposit as a whole by criterion of maximum oil recovery with minimum expenditures of resources and time.

EFFECT: higher efficiency of development and operation of deposits due to reduced time for design works and improvement of their quality.
