“…Every year, dozens of activities are carried out at each oil field in order to regulate its development and maintain target oil production levels. This set of works is called geological and technical measures (hereinafter GTM), the implementation of which ensures the fulfillment of design indicators in order to regulate and continuously manage field development and maintain target oil production levels [11][12][13][14].…”

In the course of the research, an analysis of the development of geological and technical measures at various fields was carried out. The justified application of these measures has been studied, and recommendations have been made to increase the efficiency of oil recovery based on drilling wells with modified valve assembly parameters. The conducted research allows us to obtain optimal performance indicators of pumping equipment associated with such parameters as pressure, flow, taking into account the lowest cost of repair work. For this purpose, modeling of geological and technical measures based on drilling a well with modified parameters of the hydraulic assembly of the drilling pump has been developed. This design solution allows you to obtain optimal performance of the drilling pump, taking into account the lowest costs for current and major repairs. These studies aimed at finding optimal geological and technical measures (GTM) related to increasing the productivity of drilling pumps and oil recovery in general are very promising and relevant.

Exploration and development of mineral deposits largely affects the dynamics of development of the oil and gas industry in the country. An important stage in the field development is the design of technologies for constructing wells, and the drilling process itself. The appropriate modes and drilling tools create conditions for the maximum oil recovery. In this paper, based on the analysis of existing well drilling technologies and features of the mining and geological conditions of the fields, the use of a new technological solution is substantiated and recommendations are given for its implementation in the Yuzhno-Priobskoye field. The feature of the Yuzhno-Priobskoye field is frequent interbedding, that is, alternation of some rock layers by others. These layers exhibit different mechanical properties, such as hardness, elasticity, and abrasiveness, which arise certain difficulties in the field exploration and development. The proposed technological solution significantly increases the efficiency of mining and geological operations.

“…The next group includes those oscillatory processes that lie in the range from 1 to 70 Hz. Speaking about the sources of oscillations of this frequency group, first of all it is necessary to note the mud pump, which, due to its design features, leads to the appearance of high-amplitude oscillations of the pumped drilling fluid inside the drill string with a frequency of about 1 Hz [3,4]. Taking into account that the actual drilling conditions presuppose the setting of the average pressure at the level of 10 MPa and above, the unevenness of the drilling fluid supply by the pumps causes not only highamplitude fluctuations in the fluid pressure, but also the swinging of the entire drill string [5].…”

When drilling oil and gas wells, downhole and drilling wellhead equipment is subject to the influence of significant vibration processes of different directions with different amplitude-frequency characteristics. The paper describes the main sources of vibration of drilling equipment, which have a downhole origin. In this paper an amplitude-frequency characteristic of oscillatory processes of a drill string and their influence on drilling performance are given. In addition to the sources of fluctuations of the bottomhole nature of origin, sources of the wellhead nature can also be distinguished. Thus drilling mud pump is a generator of pulsations and beats of the pressure of drilling fluid, which in turn leads to the increase in the dynamics of the drilling tool, the appearance of torsional vibrations of downhole motors and bits. We established the negative influence of vibrations of the bottomhole assembly and drilling mud on the stability of the operation of hydraulic downhole motors, penetration on the bit, durability of the elements of the string and energy indicators of drilling. The proposed device allows reducing the amplitude of pressure fluctuations of the drilling fluid and drilling tool.
