研究水下油罐贮含水原油采用“油水置换”工艺的可行性。通过对含水原油的静态、动态沉降模拟试验研究，揭示了“油水置换”流程运行油水界面不产生乳化层的规律，在进油排水、进水排油过程中置换出来的海水含油量不超标，满足工艺要求，论证了“油水置换”工艺的可行性。
The feasibility of using “oil-water replacement” technology to study underwater crude oil storage and storage of crude oil is studied. Through the static and dynamic subsidence simulation experiments of water-containing crude oil, the law that the emulsion layer does not produce at the interface of oil-water displacement is revealed. The oil content of seawater displaced during oil-in-water drainage and water- Meet the process requirements, demonstrating the “oil and water replacement” process feasibility.
