Temperature and pressure are two important parameters in the management, design and dynamic analysis of gas well. In this paper we establish a numerical model of temperature and pressure distribution for gas well based on fluid phase theory of gas well and mass, momentum and energy conservation. The model, which accords with the actual situation of the gas well, allows for the oblique angle, structure of well and tubing string, the radial heat transfer of the wellbore, different heat transfer medium in annular and the physical character of the stratum. We set up four order Range-kuta method to solve the numerical model. In calculation, we divide the wellbore into several intervals. Temperature and pressure are just the unknown factors in every interval of the object, and it is necessary to use iterative method to solve them. Then we compile the corresponding simulation software with computer programming language named C] to simulate the temperature and pressure distributions and plot the distribution curves based on the basic data of Da Well.
The curves can reflect the gas flowing law intuitively and provide the technical reliance and dynamic analysis of production well. Ii Modeling flowing wellbore fluid transient temperature is important in many petroleum engineering problems, including, pressure transient testing, flow assurance and wellbore integrity during production, preservation of drilling equipment integrity for geothermal wells and prediction of injection fluid temperatures.

In this thesis, development and usage of three models for transient fluid temperature are presented. Two models predict transient temperature of flowing fluid under separate flow configurations and one is for a static fluid column. Theory Of Dielectrics Frohlich Pdf Editor there. Additionally, an improvement to an existing transient temperature solution is given. The transient rate model predicts the transient temperature when a flow rate, during production, is changed from some initial value to a new one. This model is particularly useful for pressure transient tests involving multiple disparate constant flow rates where bottomhole pressure has to be calculated from the wellhead pressure.
Dependence of fluid density on variable temperature during the test necessitates that effects of unsteady.
