Abstract
To predict the dog-leg severity (DLS) of well during drilling using RSS for oriented drilling of wells with horizontal section, the differential equations of the elastic line of the BHA have not been calculated and the forces arising from the interaction of the BHA with the well wall, depending on the axial load on the drill string, have not been determined. At the same time, the current trend in the development of the directional drilling industry involves the active introduction of rotary steerable systems (RSS) as high-tech equipment that allows to multiply the length of horizontal sections of oil and gas wells and thereby increase the drainage zone of the productive reservoir.
At the same time, the development of domestic measurement while drilling (MWD) tools the localization of their production are actively developing. Russian RSS developers have a unified approach to the design of the system, which consists in the possibility of using various MWD modules in conjunction with the developed RSS. The reason for this approach is the prevalence of a sufficiently large number of MWD operating on the basis of a hydraulic communication channel. The obvious task is to find a solution for the selection of a non-magnetic drilling collars (NMDC) for MWD module for RSS according to the technical and technological conditions of drilling. A calculation based on the results of an analytical study of the interaction of NMDC with RSS with the well wall is presented, assumptions for even models are determined, and the values of the force on the bit and the force on the RSS dies with different axial loads on the drill string are compared.
