“…At the same time, the moment in the indicated range varies from 1 to 4.5 kN m, which is sufficient for the implementation of volumetric destruction of rock. (2) In the case of operation of the SDM in extreme mode (maximum power mode), a sharp increase in the amplitude of oscillations occurs in the lower part of the SDM, which leads to the appearance of half-waves in the BHA and loss of tool stability. (3) The mathematical model has been improved, which allows to determine the diameters of the drilling operational parameters that ensure the BHA stability by controlling the dynamics of the «SDM-DS» system during its joint operation.…”

“…Implementation of such profiles involves the use of a rotary steerable system (RSS), or SDM as a drill bit (DB) drive. The use of expensive RSS [2] is economically unsuitable. Therefore, in most cases (70-80 %) such wells are drilled by using SDM in Russia.…”

“…Yigit and Christoforou [4] studied the coupled axial and transverse vibrations of oilwell drillstrings. Optimizing the drilling parameters such as weight on bit, rate of penetration (ROP) and structure of drill string and bit are of great interest to researchers and energy industries, academically and practically [5][6][7][8]. The effects of downhole assembly and polycrystalline diamond compact (PDC) bit geometry on stability of drillstrings were studied by Elsayed et al [9].…”

Due to the world increasing energy demands, optimizing the drilling system parameters such as the weight on bit (WOB), and the structure of drill string and bit, also vibrations and dynamic behavior of drill strings are of significant interest to researchers and energy industries. Specially, to overcome limitations of drilling operations in oil and gas industry, composite drill strings as high-tech devices are under development. In this research, the fully coupled non-linear axial vibrations of composite drill strings due to the interaction of two common bits namely; Roller Cone (RC) and Polycrystalline Diamond Compact (PDC) with rock, considering the major non-linear terms, the drill string-wellbore contact, the different weight on bit (WOB) and the different composite configurations using the finite element method (FEM) and the Lagrangian approach were studied. This study proved that the different configurations of composite drill strings showed specific dynamic behavior at different conditions. Therefore, composite drill string can be designed for particular purposes. Also, the results imply the remarkable effects of weight on bit (WOB) and type of bits on the axial vibrations of composite drill strings.

The force and deformation analysis of the bottom hole assembly (BHA) is the foundation and essential component of good trajectory control technology. Still, the BHA structure has complexity (multiangle), making it challenging to analyze the force and deformation of the BHA accurately. In this paper, we consider the factors such as well drilling parameters (drill pressure), drill combination structure parameters (multivariable cross section, stabilizer, and flexible short section diameter and position, etc.), a mechanical analysis model of the push-the-bit rotary steering tool is established based on the infinitesimal method and continuous beam-column theory. Taking the push-the-bit rotary steerable drilling assembly as an example, the influence of force and deformation of the rotary guided drilling assembly, such as drill pressure, stabilizer, and flexible short section parameters, was analyzed. The research results of this paper can solve the mechanical modeling problem of the variable cross section in the bottom drill combination, can deal with the combination of infinite multiple stiffnesses according to the actual situation, bring the analysis results closer to the real problem, and provide theoretical support for the design optimization of the bottom drill combination. In addition, edge computing can provide sufficient computing power for the calculation of this paper to ensure operational efficiency. It can realize the online real-time transmission of mechanical analysis results through powerful calculation examples and effectively guide the field operation.
