Beschreibung
Zusammenfassung:	The invention discloses a 3D simulation simplification method for electromagnetic wave logging while drilling. The method comprises the steps that s1, acquiring instrument parameters, a stratum model, the relative position relation between an instrument and a stratum and other information; s2, determining a forward modeling initial computational domain of the electromagnetic wave logging while drilling; s3, performing mesh generation on the initial computational domain; s4, judging whether the model is symmetrical about an XOZ plane or not, if so, executing the step s5, and otherwise, executing the step s8; s5, judging whether the model is symmetrical about a YOZ plane or not, if so, executing the step s6, and otherwise, executing the step s7; s6, generating a new computational domain of a quarter space according to the symmetry of the model; s7, generating a new computational domain of a half space according to the symmetry of the model; s8, performing electrical parameter assignment on each cell; s9, applyi
