Pu Qian Block Thermal Stress Calculation Of Casing Columns

For thermal recovery Steam Flooding there is a high proportion of casing damage in question,Steam drive drilling in cementing quality, well structure, such as completion and well is a big difference between normal adjustment.This article to casing-cement ring-formation for research object, in ideal status by uniform within pressure, and uniform to stress, and temperature load, common role Shi of hosted characteristics for analysis, used plane183plane strain unit, on casing-cement ring-formation for unit discrete, established casing column limited Yuan mechanical model, derivation and established has displacement function, and shaped function of calculation equation, by is cases description model and calculation method of feasibility.The combination of shallow heavy oil reservoir development and Pu Qian block,According to the reservoir formation conditions and fluid characteristics and production process requirements, Casing material selection, stress calculation of stress calculation of casing string and casing thread, Optimum meet the requirements of thermal recovery of Pu Qian block completion.
