Determination of reliable values of filtration parameters of productive strata is the most important task of monitoring the processes of developing reserves. One of the most effective methods for solving the problem is hydrodynamic testing of wells using the pressure recovery method, as well as modern methods - the pressure stabilization method and the method based on production analysis (Decline Analyze). This article is devoted to the assessment of the reliability of these three methods in determining the filtration parameters of terrigenous and carbonate productive deposits of oil fields in the Perm Krai. To solve the problem, multivariate regression analysis was used. A series of multidimensional mathematical models of well flow rates was built using filtration parameters determined for each of the methods. It is proposed to consider the filtration parameters included in the models with the maximum statistical estimates of performance as the most reliable. With regard to the fields under consideration, it was found that in terrigenous reservoirs, all three methods demonstrate stable results. In carbonate reservoirs, reliable values of filtration parameters are determined by processing pressure build-up curves. Pressure stabilization and production analysis methods show less robust results and require additional research in order to develop sound recommendations for their practical application.

The cultivation of seedlings in forest tree nurseries for reforestation and afforestation is an important task of forestry. For sowing seeds of coniferous species in forest nurseries seeder with coil sowing machines are used, which do not provide the desired uniformity of seeding and damage seeds when sowing. Pin sowing machines allow you to eliminate these drawbacks, so research process is interested for forestry. As a result of the research of the process of sowing seeds of conifers by sowing machines with pin metering apparatus, formulas for determination of its angular velocity and rotational speed of the drive of furrow making roller. Formulas to determine seeding rate are proposed, taking into account constructive parameters of seeding machine and size of pins. It is noted that the increase in height and width of pins and also fill factor and number of rows of pins leads to the increase in standards; and increase in gear ratio of the actuator causes its decrease. Uneven supply of seed increases with increased size of pins, so thickness of pins is recommended to be minimum one, taking into account its sufficient strength. Conducted analytical research of the process of work of pin sowing unit enabled to obtain the necessary expressions for calculating structural and technological parameters of the forest sowing machine for sowing seeds of coniferous species in forest nurseries.

The goal of the work. Investigate the influence of the relative position of the depth of processing with a chisel, the speed of movement of the unit and the distance between the cutting side discs on the lumpiness of the processed strip. Methods of research: analytical - quantitative determination of the quality of strip tillage; laboratory-field - for research, an experimental installation was completed with an MTZ-892 tractor and a section of the unit for strip tillage; statistical with generally accepted agronomic and economic methods. Results. Experimental studies of changes in the design and technological parameters of the unit for strip processing with the determination of lumpiness have been carried out. To study the main parameters, the depth of processing of the subsoiler (chisel) is taken from 13 to 27 cm, the distance between the cutting side discs is from 10 to 30 cm, the speed of the MTA is from 4 to 11 km/h. Unchanged parameters during the study: the distance from the axis of the front disc to the chisel is 50 cm, the distance from the chisel to the axis of the cutting side discs is 50 cm, the immersion depth of the cutting side discs is 10 cm. Experimental background is winter wheat stubble. Soil cultivation for winter wheat - deep (18 cm) disking, before that plowing to a depth of 25 cm. According to the research results, graphs of the dependence of lumpiness on the relative position of the chisel, cutting side discs and changes in the speed of the MTA were built. As the speed and distance between the side cutting discs increase, the lumpiness value decreases. Conclusions. Based on the results of the studies, the dependences of lumpiness on the relative position of the chisel and cutting side disks were obtained when the speed of the MTA was changed. It was determined that with an increase in the processing depth, the distance between the cutting side discs of 20 cm and the MTA movement speed of 7.5 km / h, a uniform increase in lumpiness is observed. The distance between the side cutting discs of 10 cm is not suitable for work.

Feed production, feeding of animals and poultry is an integral part of animal husbandry and poultry farming. Proper feeding of animals and poultry, which implies the making of an optimal diet with the input of useful premixes and vitamins, can increase their productivity. In Russia the predominant type of feeding is complete feed, which includes compound feed. Regardless of the type of feed in the process of its production, it is necessary to observe the proportions of its components. Dispensers are used for dosing, which depending on the purpose, are divided into mass and volume. We have made an attempt to generalize, systematize and implement the accumulated experience in the form of a scheme that allows us to understand the principle of operation of modern systems for dosing feed components, in which augers are used as feeding mechanisms. The purpose of the research was to build a scheme for selecting parameters and develop a methodology for studying the dosage system of feed components based on it. The results of the analysis of intellectual property protection documents and scientifi c works in the fi eld of dosing have been used to make a scheme for selecting parameters of the feed components dosing system. The results of observations on the operation of the developed system under production conditions and design features have been also taken into account. As a result of the research developed the scheme of selection of the operating parameters of the dosing system, revealed its shortcomings in the form of lower dosing accuracy with the decrease in the mass of the weighed components and the long search settings when composing the new diet. The methods have been developed to address the identifi ed defi ciencies in the determination of limit values of technological parameters.
