    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

This direction is resource saving, minimizing the volume of field trials in the search for optimal technological solutions. The main aim of the research was to develop an improved method for selecting drilling bits from statistical data on the mechanical properties of formations. Objects: identification of drilling bits of different firms and their selection in accordance with the statistical characteristics of the mechanical properties of formations. These issues are poorly understood and cause difficulties in the design of well drilling regimes. Methods: graphoanalytical study of the correspondence of the types of drill bits to the strength characteristics of formations determined by Unconfined Compression Strength and the method of Static indentation of a stamp with a flat base. Results. The International Association of Drilling Contractors (IADC) has developed a single classification in IADC codes for identification of bits of various manufacturers. For domestic drillers a dilemma arose: formations are characterized by hardness according to the stamp and in categories, and the bits are made in accordance with the strength of the formations in the IADC codes. The authors pro- pose a transition to the index of formation strength, expressed in the codes of the IADC of bits. This ensures the uniformity of characteristics for both bits and rocks. Accordingly the authors proposed nomograms for selection of bits on statistical value of toughness of formations in codes IADC, calculated with reliability of 0,95. It is shown that it is possible to select bit similarly when representing hardness of formations in categories. In the case of blade diamond carbide bits, their choice is divided into two stages: the choice of the type of a bit in accordance with the strength of the formation in codes or with hardness in categories and the calculation of the number of blades of the bit, which depends both on the toughness characteristics of the formation, and on the diameter of the bit. To simplify the choice of bits, it was suggested to characterize the drillability of formations of the allocated intervals not verbally (soft, medium and so on), but by their statistical characteristics in IADC codes or in the categories with a given probability

There are active Interval Control Valve (ICV) or passive Inflow Control Device (ICD). ICD devices are able to equalize the inflow along the horizontal well, creating additional resistance to fluid flow, depending on the amount of inflow in this horizontal section. The drawback of modern ICDs is that they do not have the ability to regulate and activate ICD after installation in the wellbore. This creates certain risks associated with the uncertainty in description of reservoir properties that are present at all stages of field development. ICV systems are operated remotely from the surface of the well, but are not able to determine the nature of the incoming fluid (oil, gas, water) into the well and make a decision in automatic mode. Objects of the research are a horizontal wells and a fluid flow control device. Methods: simulation Simulink, neural networks, matrix methods, methods of linearization of nonlinear equations. The main aim of the research is to development of a new design scheme of the inflow control device, with the possibility of continuous monitoring of the nature of the incoming liquid, and software for controlling the valve with the wellhead. Results. The authors have proposed a new design scheme of inflow control device in a horizontal well, which helps continuous assessment the nature of the incoming fluid. This design allows you automatically adjust the position of the actuator mechanism, as reported by measuring instruments. The mathematical description of the valve operation is given. The model of the valve was developed in Simulink simulation environment, using the matrix approach and neural networks, to build a qualitative dependence of the valve position on pressure drop value. The results of the neural network block operation and the final result of modeling are presented

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
