RESEARCH ON THE INFLUENCE OF MARBLE POWDER ADDITIONS ON THE CHANGE IN BURNING METHODS BASED ON BENTONITE CLAY, KMS, AND OPR

Abstract

This article examines and analyzes the dependencies of changes in drilling fluid parameters when marble powder is gradually added to the initial drilling fluid composition. Based on experimental data, the dependence types of solution parameters were determined. Using the correlation coefficient and the least squares method, formulas were derived to predict the density and flow time of the conditional viscosity from the SPV-5 device. The results obtained allow for the prediction of several parameters of drilling fluid values in real drilling conditions under field conditions with a known mass of marble powder in the composition. Using the method presented in the article, it is possible to predict the arbitrary parameters of the drilling fluid at a known mass of the required reagents to be added. Furthermore, the obtained experimental results prove that the higher the mass of the marble powder added to the initial solution, the lower the filtration, the thinner the crust, which ensures no trapping, and with higher viscosity values, the removal of sludge increases significantly. A formula has been determined that predicts with the lowest error the density and leakage time from the SPV-5 device of drilling mud based on bentonite clay, KMS, and OPR with the addition of marble powder.
