Effect of Bottomhole Assembly Dynamics on the Trajectory of a Bit
Web19 de jan. de 2024 · The closest stabilizer to the bit acts as a pendulum point. Gravity tends to force the bit to the “low side” of the hole, decreasing hole angle. Pendulum BHAs are … WebSummary This work, which reports on the effect of bottomhole assembly (BHA) dynamics on the trajectory of a bit, is part of an on-going effort to develop a computer model that simulates the three-dimensional (3D) movement of the bit. A theoretical description of the dynamic version of the 3D finite element algorithm is presented. The basic mechanisms … Webstring and the borehole wall, and the force on the drill bit. 2.1 Coupled dynamics model As mentioned above, the downhole situation is complex and there are many influencing factors. As an important tool for drilling, the mechanical analysis of the bit in the drilling process is the basis of bit trajectory prediction [21, 22]. Firstly, the force how many avengers died in endgame
