QUANTITATIVE ASSESSMENT METHOD STUDY IN THE PRESSURE BEARINGLIFE OF FIBERGLASS SIMULATION CASE

Abstract

Abstract: Fiberglass simulation cases have undergone heat accelerated aging test and hydraulic blasting tests in different temperature conditions. By blasting pressure-aging time regression analysis in different aging temperature, aging equation and performance coefficient of variation were obtained. Based on the aging equation and performance coefficient of variation regression analysis, case performance coefficient of variation in normal temperature was extrapolated, and then the internal pressure bearing age equation in normal temperature was obtained. The relationship between the regression curve judged by the relevant index was obvious. Based on the blasting pressure data of simulation cases after accelerated aging test in heat-humid environment and natural storage case, aging equation was fixed. Studies have shown that fiberglass case burst pressure and reservoir simulation time performed logarithmic relationship, full-size fiberglass shell burst pressure was 9.97 MPa in the initial state, and it was predited that the full-size fiberglass shell burst pressure decreases 9.5% 20 years later.
