Abstract:
The step-moving can realize the all-round moving of rigs with the feature of fast moving and convenient operation, so it is widely applied in cluster wells. In order to understand if the in-service electric rig installed with step-moving device can settle the problem of rig all-round moving with full stand,a structural stress monitoring and test of rig moving is carried out. In this paper,a ZJ50DBS rig of CDEC is the research subject,finite element analysis is adopted to identify parts of the rig structure bearing larger force when lifting,and regard them as the stress monitoring points. Then the rig moving stress monitoring is done in the condition of no stand. Based on the data analysis,strength check results are the target,and rig structure finite element model is modified. Finally,the full stand load is applied to the modified rig model,and then stress is analyzed. The results show that the rig after installation of step mobile device,is of sufficient strength to move at full stand condition.
Key words: electric rig, step-moving, stress monitoring, model correction, strength check
