Application of Temperature Fall-Off Interpretation Method in Superheavy Oil or Oil Sand SAGD Process

چکیده
SAGD technology has been successfully and widely applied in the development of superheavy oil sand projects. Before normal process, some preheating ways are often needed to realize interwell hydraulic connection, this means that determining reasonable conversion timing from stage is an essential precondition for good performance. Previous numerical simulations or qualitative analysis temperature fall-off data adopted industry, but they have deficiencies terms dependent on static geological model insufficient utilization. Therefore, basis pressure monitoring process comparison China’s Canada’s projects, paper proposed a interpretation obtain thermal diffusivity radius at different measurement points along horizontal section by combining unsteady conduction under constant heating power wellbores radial coordinate system approximately with wellbore Fourier’s law conduction. Besides, duration time, method, application flow chart test were presented. Then, it was validated determine example tracking simulation, inflection point analysis, index during partial-SAGD initial stages. The findings study can help simpler faster especially case long well deployed more points.

Pumping Oil Sand Froth
Froth is the basis to the extraction of bitumen from oil sand. Its components include sand, bitumen, water, and air. The technology of extraction and processing is evolving toward lower temperature of operation where the volumetric content of air and viscosity of bitumen challenge pumping. To improve the efficiency of froth handling pumps it is important to adapt the technology from other indus...
متن کاملPerformance of helical piles in oil sand
The results of a comprehensive pile load-test program and observations from field monitoring of helical piles with either a single helix or double helixes installed in oil sand are presented in this paper. Eleven full-scale pile load tests were carried out including axial compression, uplift, and lateral load tests. The results of the full-scale load tests are used to develop a theoretical desi...
