    Relevance of the work is determined by the task of developing low-toxic, biodegradable and inexpensive reagents for water based drilling muds chemical treatment. In this connection, the paper considers the methods for increasing the reactivity of neutral-sulphite liquors used as the basis of such reagents. The aim of the research is to study the feasibility of using phosphonic compounds in preparation of reagents based on neutral-sulphite liquors for treatment of drilling flushing fluids in order to improve their technological parameters Research methods: instrumental methods for determining drilling fluids parameters for taxiway 39-00147001-773-2004 ([ro] is the density, RV is the relative viscosity, [ita]pl is the plastic viscosity, [tau]0 is the yield point, the SSS is the static shear stress, IF is the index filtration, pH is the index of hydrogen ions content) supplemented with neutral sulfite liquors phosphonic compounds in acid nitrilomethylenephosphonic, sodium tripolyphosphate for both separate and combined entering into composition of drilling liquid Results. It was ascertained that inclusion of phosphonic compounds in composition of drilling reagents based on the neutral-sulfite liquor allows improving quality indicators of drilling fluids, contributing to sustainability of drilling system parameters to exposure of higher downhole temperature and mineral aggression providing high-thinning ability and reducing the drilling mud filtration rate. These properties of drilling reagents, modified by phosphonic compounds, allow converting low-reaction liquors used as the basis, to the part of the advanced resource-renewable domestic raw materials. Conclusion. Investigation of physicochemical properties and characteristics of liquors of neutral-sulfite digestion showed that, in spite of the reduced reactivity, they are a very promising component for reagents obtaining, especially in conditions of increased demand for renewable raw materials sources

It is important to carry out experimental studies for evaluating the impact on filtration capacitive properties of core material selected at Polar oil-gas condensate deposit. This direction is relevant due to the need to preserve collector properties of productive formations and productivity of wells during their construction and development. The main aim of the research is to form a list of recommendations for planning and conducting filtration studies on core material when assessing the influence of process liquids on the filtration and capacitive properties of rocks. Objects: core material - sandstone fine-grained, aleuristic with signs of hydrocarbons; selected at Polar oil-gas condensate deposit; solutions of initial opening of various systems - on water and hydrocarbon bases; fresh polymer clay and KCl polymer carbonate drilling fluids. Methods: study of the degree of damage of filtration-capacitive properties of the formation by various process liquids; estimation of values of recovery coefficients of initial permeability of core material taken at Polar oil-gas condensate deposit under different conditions, which are as close as possible to formation conditions by values of formation pressure and temperature. Results. The authors have developed the list of recommendations for planning and conducting filtration studies on the core during selection of process fluids for formation opening. Real examples show the key points of the methodology, in case of non-compliance of which it is possible to obtain an erroneous understanding of conformity or non-conformity of the tested process liquids to the opened objects of operation
