Understanding torsionay streslas is im strings its essential for are and empiticient drillingg operations. Ini pedoman diberikan sebuah clear, step-mortal s to decie the torsionala stress experience by dril strings durindle driling actipiees.

Begin by conveniog information thale drillingg ocment, including the bobot on bit, drill string properties, and rotationaliaI speeded. Thees paremeters influence the torsionala al forces s acting on drill string.

Calculating Torsionala Torque

The torsionala torque (T) can be estimatech using the formula:

1f 1st; FLT: 0 133; Abo3; T = (jt * L * jt) / r voi1; FLT: 1: 1 3; 133;

Dimana:

  • 1f 1f; 1f 1f; FLT: 0 = 0 = 323; Aver3. 1; FLT: 1 123; = shear module of the drill pipee material
  • 1f 1f; FLT: 0 = 0 = 33; L = 11; FLT: 1 123; = length of the drill string section
  • 1f 1f; 1f; FLT: 0 = 33. Abo3; Aver1; FLT: 1 123; = angular velocity (radians per second)
  • 1f 1f; 1f 1f; FLT: 0 = 0 = 333. r 1r; 1f; FLT: 1 123; = radius of the drill pipe

Deterding Torsionala Stress

The torsionala stress (Average) is kalkulated by dividing the torque by the polar mout of inertia (J):

111; WHI1; FLT: 0 AF3; AF3; AND = T / J = R / J RIPH1; FLT: 1 123; AND 3;

Ini adalah sebuah petunjuk yang sangat penting.
