COMPOSITE TUBING LINERS FOR OIL AND GAS PRODUCTION

摘要

In this study, a glass reinforced epoxy (GRE) liner was systematically designed using a highrntemperature epoxy resin system reinforced with high strength E-glass roving. This GRE linerrncould theoretically be used in conjunction with standardized oil and gas production tubing tornalleviate the effects of corrosion in offshore exploration applications. The composite system wasrndesigned using netting analysis for filament wound pressure vessels and tested in accordance withrnASTM D-2290 split-disk procedures. Furthermore, the epoxy matrix was environmentallyrnconditioned and evaluated to assess the proposed system’s susceptibility to fluid absorption duringrnimplementation. To ensure that the finalized design would be capable of withstanding the immensernpressures and temperatures seen during use in offshore oil and gas production, the project used anrnAPI controlled steel alloy, already employed by industry, as a benchmark for determining thernnecessary yield stress and internal yield pressure required for the proposed application. The studyrnwas conducted with the intent to utilize the design principles of filament wound pressure vesselsrnto produce an oil and gas production liner that emulates the strength characteristics of its steelrncounterpart, while retaining the corrosion resistance associated with epoxy systems.
