TUBULAR STRING CHARACTERIZATION IN HIGH TEMPERATURE HIGH PRESSURE OIL AND GAS WELLS
|Author(s)||Jiuping Xu, Zezhong Wu|
In applied basic theory for deep well testing research, tubular string mechanical analysis is complex as fluid temperature and tubing pressure have a large effect on the force of the tubular string. When well testing, the methods used for determining the temperature and the pressure of the tubular string include measurements from thermometers and pressure gauges located in the tubing, temperature and pressure measurements at only the well bottom and well head. With these measurements, it is possible to predict the complete distribution using theory analysis technology. Predicting accurate temperature and pressure profiles in flowing wells can greatly enhance oil and gas production. However, for gas wells with High Temperature High Pressure (HTHP), it is often difficult to operate thermometers and pressure gauges within the tubing itself, and therefore theory analysis can be used as an effective and feasible method.cost and time.
