Wherein φ is the azimuth of required point, and unit is rad；φ1For the azimuth of the 1st neighbouring sample point, unit is rad；
φ2For the azimuth of the 2nd neighbouring sample point, unit is rad.
6. a kind of plane well location air navigation aid based on well logging information foundation according to claim 2 is it is characterised in that institute
State the calculating that coordinate transformation unit (9) in oil carries out shift offset using radius-of-curvature method, realized by following methods：
According to radius-of-curvature method geometrical principle, derive thing shift offset, shifting between south and north side-play amount：
WhereinΔ α=α-α1, Δ φ=φ-φ1；
3. middle Δ E is the thing shift offset of required point and first measurement point to formula, and unit is m；4. middle Δ N is required point to formula
With the shifting between south and north side-play amount of first measurement point, unit is m.
7. a kind of plane well location air navigation aid based on well logging information foundation according to claim 2 is it is characterised in that institute
State coordinate in oil to be respectively：
X=Ln1+ΔN+X0⑤
Y=Le1+ΔE+Y0⑥
In formula：X is vertical coordinate in required point oil, and y is abscissa in required point oil, Ln1It is neighbouring first measurement point with respect to well
The shifting between south and north of mouth, unit is m；Le1It is the thing displacement that neighbouring first measurement point is with respect to well head, unit is m；X0For well
Mouth vertical coordinate, Y0For well head abscissa.
