PRODUCTION OF DRILLING FLUIDS BASED ON COTTON SOAPSTOCKS

Abstract

Introduction. For effective oil production, this is necessary to ensure high-quality drilling, opening of reservoirs. Many tasks that-arise during drilling are solved with the-help of-process fluids. The purpose of the work is to create new drilling fluids based on secondary resources, surfactants. The composition of-a new drilling mud for drilling wells is proposed. Methods. One of-the main indicators of hydrophobic emulsion solutions is filtrate output. The operational properties of the filtrate-release of hydrophobic emulsion solutions differ slightly from other indicators. When filtering hydrophobic emulsion solutions in a porous-medium, the kinetic factor associated with the-rate of formation of the filtration crust becomes of great importance. Results and discussion. The instantaneous filtrate output of-systems of hydrophobic emulsion solutions stabilized by surfactants is reduced due to the rapid formation of a bound filtration crust by means of-fast interactions, therefore, it’s strengthened by slow interaction bonds. This formation of charge-transfer complexes, electronic donor-acceptor, long-lived free stable radicals, hydrogen, covalent bonding carried out with an induction period at a close distance, determines a decrease in-the filtration yield of the solution. Conclusion. Cotton soapstocks are valuable additives in the composition of drilling fluids-to improve their operational properties. According to the limit values of the parameters, the-reagents are arranged in the following-series according to-filtrate: fatty acid salts > emultal > soapstock > tar distillation of fatty-acids. At the same time, the parameters of the hydrophobic emulsion solution are always, except for GJC and FFA, where after the limit value of their quantities, the filtrate output increases, improves with-the concentrations of-reagents.
