“…Cuttings are transported due to the action of the buoyancy of the drilling fluid flow and the resistance forces acting on the cuttings particles in the process of its settling. This is superimposed by various effects caused by the rotation of the drill string, uneven velocity distribution profile, changes in the geometric parameters of the well trajectory and the crosssectional area of the annulus, the shape and size of cuttings, changes in the rheological parameters of drilling fluids, and the eccentric location of the drill string (Zamora and Hanson, 1991;Femiak et al, 2022).…”

The main factors affecting the efficiency of the carrying capacity of drilling fluid are analysed in the paper. A description of the design of an experimental setup for modeling the well flushing process is presented, which makes it possible to evaluate the efficiency of the carrying capacity of a fluid from a variety of factors under study. To conduct experimental studies of the influence of factors on the efficiency of cleaning wells from cuttings, an experimental plan was built using the Taguchi methods for six factors at three levels of their change. According to the plan, we studied the effect of such parameters on the carrying capacity of the drilling fluid at various values of its flow rate: the variability of the drill string in the well; the cuttings particle diameter; the plastic viscosity of the drilling fluid; the pulsation frequency; the rotation of the drill string and its longitudinal movement. The nature of the formation of stagnant rock zones in the annulus of directional wells has been assessed. The influence of factors according to the constructed plan of the experiment at the distance of the beginning of settlement of the cuttings was studied. Based on the results of the studies, it was found that changing the range of these factors reduces the volume of rock deposited on the lower wall of the directional wellbore. It has been established that the use of a pulsating flow of flushing fluid makes it possible to reduce the value of its consumption and improve the efficiency of cleaning the annular space of wells from cuttings.

To implement remote binary supply of GC for a safe and appropriate distance, developed an autonomous extinguishing system with gel-forming compounds AUTGOS - M, the design of which is shown in Fig. 1 [1]. This installation contains a supporting frame (frame) 1, where two tanks 2 with increased capacity of the components of the GC solution and two cylinders with compressed air 3, which have indicators of visual control of pressure in the tanks 4 and are connected by a direct action reducer. Moreover, the components of the GC contained in the containers under the pressure of compressed air, due to the system of connecting flexible hoses 5 are in the spray nozzles 6, which have one tap for closing and opening, which is associated with separate or joint supply of components GC on the object of fire extinguishing. The proposed design differs in that it additionally implements a system of guidance of spray barrels 7 on the object of fire extinguishing with verification by angles of inclination to the horizon, angles of deflection, height and base width of symmetrical placement and fixation of spray barrels mounted on the supporting frame ( on the frame) [1].
