The invention discloses an oil-water well casing damage early warning method and device and a storage medium, and the method comprises the steps: determining an oil-water well casing damage early warning index; determining the comprehensive risk degree of casing damage according to the casing damage early warning index of the oil-water well; and determining the risk grade of the oil-water well according to the comprehensive risk degree of the casing damage, and carrying out early warning on the casing damage of the oil-water well based on the risk grade. The method aims to solve the problems that an existing method is poor in operability and cannot meet actual production requirements, and the problems that an oil field lacks an accurate, quantitative and rapid single-well casing damage risk evaluation method, targeted risk regulation and control are not facilitated, and the number of casing damage wells cannot be reduced are solved.
Description
technical field [0001] The invention relates to the field of oilfield casing damage prevention and control, in particular to an oil-water well casing damage early warning method, device and storage medium. Background technique [0002] With the increase of the development period, most of the sand (conglomerate) oilfields developed by water injection in my country have entered the development period of ultra-high water cut, the well pattern density is increasing, the pressure difference between layers and layers is increasing, and the underground situation is getting worse. The more complicated it is, coupled with the deterioration of the downhole process conditions and the aging of the casing itself, the number of wells with casing damage in the oilfield is increasing year by year, and the situation of casing damage is becoming more and more serious, which seriously affects the normal production and development benefits of the oilfield. In order to control the situation of ca...
