The article deals with the problem of investigation system "soft starter- induction motor" for compressing equipment cone drilling machine. Also refined mathematical model system, taking into account behavior compressor load, as well existing working algorithm stator current control block is developed. problems choice starting mode are considered, necessity full research electric drive methods ...

Abstract Introducing the non-productive time (NPT) concepts in 1960s was a necessity dictated by ever-increasing cost and complexity of oil gas well drilling. The NPT definition stayed unsettled until two decades later, converged toward its accepted current “the when planned or out-of-plans drilling-related activities do not add value to operation objectives.” as it is defined drilling nowadays...

Abstract RamRig hosting system is a common for offshore and onshore drilling rigs, which uses ram cylinders to lift lower the top drive on rig. In order ensure accuracy, stability robustness of synchronous control system, RBF neural network used adjust PID parameters online, three loop simulation model based optimized controller built in AMESim Simulink. The results show that hydraulic circuit ...
