| Abstract. The article examines the processes of forecasting abnormal reservoir pressure in oil and gas wells and identifying abnormal zones. Some accidents and complications arising as a result of abnormal reservoir pressure are considered. A method for predicting abnormally high reservoir pressure is proposed. The method is based on the use of the relationship between the technical parameters of the drilling process. A prototype of a forecasting system operating on the basis of the method has been developed. For this purpose, a schematic technical solution of the system, an operating algorithm and a control program in the C++ language and other engineering solutions have been developed. In order to ensure the intelligence of the forecasting process, software blocks have been developed that compare current drilling parameters with the design documentation for well construction and take into account the drilling results of previously drilled wells located nearby. The functionality of the prototype was verified through computer modeling experiments in laboratory conditions. The experiments used a data block of real mechanical drilling parameters obtained from a borehole during the implementation of the SOCAR grant project. A brief description of the system's operation is provided. |
