Abstract: Abstract:A model for optimizing and controlling condensate gas well performance is developed by applying the theory of complex system control, which can reflect the reservoir, wellbore and surface safety as well as maximizing economic benefit, including the approach for the model solution, by taking the equations related to reservoir multiphase flow, wellbore multiphase fluid, well bottom and surface throttling as the state equation, and taking wellbore fluid loading, reservoir critical damage, equipment critical corroding and hydrate control of wellbore and surface as restriction condition. The development and solution of this model could deal with the co-optimizing and co-controlling problems under the multifactor and multi-feedback during condensate gas well production.
