Especially, the oil derrickw ill be subjected to the transient mi pactwhen it iswork ing during the processes of drilling and tripp ing dril-l p ipes. In this paper, the dynam ic response of oil derrick of type ZJ15D used at present in DaqingO ilfield is calculated by finite element sof-t w are ANSYS, smi u lating the typicalw orking cond itions smi ultaneously. The conclusions are as follow s: the dynam- ic response from the orientations of derricks columns, flanks and foreside is produced smi ultaneously under trans-i ent
