Research On Safety Warning System Of Oil Derrick In Service

In the long service of oil drilling derrick,there will be different damage and defect in the parts of the derrick due to various influences.The actual state of derrick differs greatly from the original design,which leads to unknown safety load.At present,the safety of derrick is assessed according to the oil industry standards,which will not reflect the actual situation.In order to monitor the stress of derrick in real time,the safety warning system of oil derrick in service is developed.The long-term monitoring strain sensor and data acquisition module are designed,and the stability test and linearity test are carried out.The software of the control system is designed.The stability of each hardware and software can meet the requirements of the monitoring system design,and the real-time monitoring data can meet the engineering requirement.With the application of the system,it is possible to get the strain of derrick in a timely and comprehensive way,and to eliminate the loss caused by the collapse of the derrick.For the derrick operation corporation,it will provide valuable information to efficiently manage the derrick and bring great social benefit.
