New Prospect Model for Liquid Loading in Gas Well Base on Energy Balance Theory

Abstract:

Accurate and timely recognizing whether gas wells get effusion is one of the important guarantee to ensure the normal production of water-cut gas well. It often gets errors when using current normal recognizing methods of the critical carrying fluid flow model to predict and recognize the actual flow situation in these wellbores, which already have effusion or have been drained effusion by taking measures. This paper is based on the coordinating relation between the energy of gas well itself and the energy required for draining effusion out, establishing a new method to recognize gas well effusion, and establishing a relatively complete system of gas well effusion identification. Combined with field production data, this method can be more accurately used to recognize gas effusion and real-time trace, and it can avoid the above problems. Combined with the instance of gas well for real-time effusion diagnosis, the predicted result is very good agreement with actual situation. This new method has important guiding significance for the normal production of water producing gas wells and the implementation of related gas recovery with water draining.
