ASSESSMENT OF EFFICIENT TIME OF DRILL BIT OPERATION, BASED ON A TECHNICAL AND ECONOMIC MODEL<\/strong><\/span>

Key words:<\/strong> penetration rate; auxiliary work time; cost per meter; bit service time; predictive estimate; control criterion; automated control system; drilling operations.
The paper looks into the issue of model representation of auxiliary works time as a function of on-bottom time. For a linear model of on-bottom time and parabolic model of auxiliary works time, a formula has been developed to find the optimal time on bottom, based on the generally accepted efficiency criteria (minimum cost per meter, maximum\u00a0 run speed). As part of the automated control system \u201cDrilling Operations\u201d, an algorithm has been created for controlling and predicting time on bottom based on the technical and economic model and the new notion of\u00a0 \u201crun-technical-economic\u201d drilling rate. An original format of representation of on-bottom time control and prediction has been provided based on a \u201cplan \u2013 actual \u2013 model \u2013 prediction\u201d scheme.<\/p>\n
