The invention discloses a while-drilling electromagnetic wave
logging cross-
dimensional simulation method suitable for a 2D model. The method comprises the following steps: s1, inputting instrument parameters, a stratum model and other information; s2, determining a while-drilling electromagnetic wave
logging forward modeling calculation domain; s3, performing variable-
scale sliding windowing
processing on the model; s4, calculating a
model complexity factor; s5, judging whether the complexity factor of the model is greater than a threshold value or not: if so, executing a step s6, otherwise, executing a step s9; s6, carrying out dimension reduction rationality analysis on a
simulation result, and calculating a
model quality control factor; s7, judging whether the
model quality control factor is greater than a threshold value or not, if so, executing a step s8, otherwise, executing a step s9; s8, calculating an original 2D stratum model response by adopting a 2.5
D algorithm; s9, solving the simplified 1D stratum model response by adopting an analytical solution to obtain a
simulation result. According to the method, the optimal
algorithm can be adaptively selected according to the stratum model to realize quick and accurate forward modeling of the electromagnetic wave
logging while drilling of the 2D stratum model.
