المسح الاتجاهي — الانحناء الأدنى

Paste MD, inclination and azimuth and get TVD, northings, eastings, dogleg severity, vertical section and closure — with the well path drawn.

كيف تُحسب

  • Dogleg angle β = arccos[cos(I₂−I₁) − sinI₁·sinI₂·(1−cos(A₂−A₁))], with ratio factor RF = (2/β)·tan(β/2).
  • ΔTVD, ΔN and ΔE are the trapezoidal averages of the direction cosines scaled by RF — the exact integral of a circular arc between two stations.
  • Vertical section is closure distance projected onto the section azimuth you choose.
  • DLS is the dogleg angle scaled to the interval you quote it over, usually 100 ft or 30 m.

أين تتوقف عن الصحة

Minimum curvature is exact arithmetic on the stations you give it, and says nothing about whether those stations are right. Real uncertainty comes from the tool: magnetic surveys carry declination, grid convergence, drill-string and geomagnetic errors that an ISCWSA error model quantifies and this tool does not. For anti-collision work you need that error model and the ellipsoids it produces, not a centre line.
