Determining technological properties of drilling muds

Purpose. To rationalize well washing by considering the influence of annular channel limitation, granulometric composition mud, limitation joint movement mud particles, drill string rotation, shape channel, and rheological properties a cleaning agent. Methodology. Applied laboratory studies on drilling fluids are carried out using modern methods analytical analysis experimental studies, in particular, general principles mathematical physical modelling, processing results EXCEL, MATNSAD environment, control measuring devices liquids Department Oil-and-Gas Engineering Drilling Dnipro University Technology (hydrometer, viscometer, plastometer, stalagmometer), materials (technical water, clay bentonite powder, reagents, stabilizers activators, surfactants as equipment base “Ukrnafta” PJSC to carry certain stages research. Findings. The surface-active substances activated analyzed. main technological studied. Comprehensive information chemical ability flushing is provided. measures ensuring stability process activated-surfactant considered detail. determining rational formulations selected agent circulation Newtonian formulated substantiated. A detailed description surfactants, their study formed solutions given. Originality. rock-breaking tool bottom will be stable conditions dynamic equilibrium processes removal broken products into space. Therefore, for correct understanding wellbore issues, basic regularities established specified various factors these processes. Practical value. It has been proven that order give fluid necessary that, one hand, ensure an increase efficiency rock breaking bottom, and, other create favourable cuttings onto surface maintenance walls condition, it apply different methods, particular activation magnetic, thermal electrochemical activation, its varieties.
