The article describes the development of the improved design of the screw conveyor of the drilling rig that is the part of the drilling mud cleaning system, as well as the general requirements for the drilling rig's circulation system. The main object is to modernize the conveyor: to lighten the maintenance, to reduce the number of repairs, to reduce the wear.

A brief review of the research aimed at improving technologies and equipment for the removal of trees and bushes on felling and line facilities is carried out. Particular attention is paid to the machines for performing these operations with the continuous movement of the machine.

The modern tendencies of creation of technics for clearing of cuttings down and linear objects are considered. Technical solutions for grinding trees, bushes and stumps using mulchers have been proposed.

The problem of developing low-yield oilfields in the Orenburg region is an important problem for the regional economy. Changes in the natural structure of pore space occur during the filtration of fluids during the development of deposits. Technological (injected into the reservoir water) and natural (oil) fluids contain a large number of solid particles of various origins - mechanical, salt, biological, paraffin, resinous asphaltene, etc. During fluid filtration, part of the pores are blocked by these particles (collation of pore systems). Considering the existing technical solutions of the devices that allow to destroy the bottomhole formation zone and revealing their shortcomings, we proposed a device for multiple hydroimpulse impact on the reservoir, which can be used in conjunction with string pumps during well development.

Proposed cleaning machines for linear objects from trees and shrubs, as well as creating firebreaks.

The necessity of creating a specialized forest machines for cleaning of linear objects from trees and shrubs, including to improve their fire safety.
