The calculation of the bottomhole treatment success probability using machine learning techniques
Machine learning is the most widely used branch of science and engineering nowadays. The availability of electronic real wide information is an important condition for implementing the machine learning. Through the long history of exploitation of oil fields, a significant database related with the wells’ development and applied techniques stimulating production was created and accumulated. The article deals with one of the machinelearning methods of analyzing the prediction of geological and engineering operations implemented in the producing oil wells. In particular, by the example of database data including the results of hydrochloricacidandmudacid jobs implemented in the oil fields of UralVolga region, as well as in terms of specific decisiontree models, the probability of successful geological and engineering operations is calculated, and recommendations on the selection of factors allowing to optimize these operations are given. The openness, average number of permeable intervals, reservoir temperature, actual well watering, fluid properties are parameters influencing the geological and engineering operations efficiency. In many cases, it is difficult to predict the influence in the future especially if other factors are available. The existing analytical models could not describe fully the factor variety in processes running in a bottomhole zone, especially in the context of nonlinear flotations, physical and chemical interaction between formation fluids and injection solutions. The described technique allows using any number of key factors and any combination of them, as well as detecting the most important of them including the parameters described, but not limited to. In this case, the application of decision tree models is an intuitive way allowing to select neatly sampling attributes at each level by the use of algorithms. The article also describes in detail the algorithm of sampling attribute calculation. Decision tree methodology can be used for solving other problems in the oil producing industry with significant practical experience.

Modelling of Longitudinal Shock of the Rigid Solid Body to the Rod Interacting With the Rigid Barrier
Shock of a solid body to a rod with a tough barrier on the basis of a wave model of longitudinal shock is considered in numerous papers of domestic and foreign researchers. Various methods of the solution of the wave equation for determination of striking power and the rod stress and strain state are used. However, creation of analytical decisions represents the awkward procedure and, as a rule, it is limited to several cycles of distribution of the created deformation wave from shock section to a tough barrier and back. The procedure is complicated by the fact that the shock system is a mechanical one with unilateral constraints and, in order to analyze the dynamic process, determination of the moment of a contact gap and transition in case of this gap to other mathematical description of the system movement is required. The article considers the wave model of longitudinal shock of a solid body to a rod. The rod is represented by a set of integrated elements of small lengths taking into account wave processes in each element, transformation of waves on borders of elements interface, and unilateral constraints in shock section. Modelling results providing a possibility of the analysis of shock process, formation and distribution of deformation waves in a shock system, creations of charts of the stress and strain state of a rod system at any time point in case of shock are provided. Longitudinal shock, shock wave model, shock to barrier, modelling, deformation waves, deformation wave transmission.

Motion Modes of Shock System for Fluctuating Force Linear Function With Changing Characteristics
Multiple technological processes are often related to using shock systems for performing of cyclic shocks on the object. Research of such systems’ dynamics, stability of motion, shock activity level requires examination of shock processes in systems with different structures. At the same time, a number of problems, confining an area of application of shock systems, arise. They are the following: finding of solutions by exact methods; taking into account complimentary nonliner factors; analysis of transient processes; detection of limit cycles of motion. These problems can be solved by means of developing the effective dynamic system simulation procedures based on the adequate mathematical models, process visualization, and representation and good processing of simulation results. The paper [1] provides an examination of the model of shock system, as well as the definition of its parameters, ensuring a required low of motion. However, a considered piecewise constant force impact may be applied to an ideal situation that is difficult to implement with a real system. Thus, it is required to know how the change of force impact would effect the mode of striker’s motion. The present paper deals with a model for shock system at force impact as linearly increasing and linearly decreasing function when force impulse, duration and period of the force impact are constant as at the piecewise constant function. A mathematical model for the shock mass motion under condition of collision with rigid barriers is given. The modeling of shock system motion at the forceimpact piecewise constant, linearly increasing and linearly decreasing function is implemented. The comparative analysis of presented simulation results is performed. The motion mode of shock system at linearly increasing and linearly decreasing functions has been changed against the mode at the forceimpact piecewise constant function (although the force impulse was constant in both cases). Following the results of implemented work, it may be deduced that the changing the force linear function characteristics, when impulse and duration of force, and part of cycles are constant at an appropriate systemparameter option, does not misrepresent the cyclic mode of shock mass motion if the process would be estimated at such criteria as velocity of shock to the right barrier, implementing of one impact per a cycle at the maximal velocity, and a cyclic behavior of impact. Shock system, motion modes of shock system, limit cycles of motion, modeling, cyclic mode of motion.

Formalization and Mathematical Modeling of the Avionics Systems Requirements for Automation of Test Design
The article deals with the automation of test design for avionics systems. The automation of test design is proposed to be made on the basis of formalization and modeling of the requirements for them. The design process accelerates when using offtheshelf modules in the product, but their use imposes more stringent requirements for the product requirement design and management, which are the basis for the product planning, management, acceptance testing, and adjusting. Based on the classical Vmodel for product definition within complex projects, the paper shows that the requirements are closely related to testing, which is directed at defects identifying and avoidance in the system, at this, the defect is regarded as a deviation from the requirements. The article gives an example for formalization and modeling of the requirements for aerobatic display frame information in an integrated system of electronic display and alarm. Based on the resulting model and the formal submission of the requirements the structure of the final test for the system is compiled. The proposed approach allows us to reduce time for testing and debugging the system, improve its quality in the sense of greater compliance. Modeling, system requirements, testing, formalization, program of operation.
