Simulation of Casing Stress in Thermal Recovery Production Wells

KANG Bo

Abstract


Thermal well technologies, such as Cyclic Steam Stimulation (CSS) and Steam Assisted Gravity Drainage (SAGD), have been widely used in the production of heavy oil reservoir. Casing failure generally exists in heavy oil thermal recovery production and becomes more and more serious. The three-dimension finite element model was developed by using ANSYS software, which applied in thermal structure coupling condition for casing, cementing hoop and rock. The influence of the parameters change on casing stress in thermal-structure coupling condition was studied. The results show that the equivalent stress can be significantly reduced by the application of high-quality insulated casing tube, borehole curvature should be as small as possible to minimum casing failure in heavy oil thermal recovery wells, casing tubes with low elastic modulus should be chosen.
