地下水封洞库储存原油与环氧树脂灌浆材料相容性表现为:2种材料长期接触后可能影响原油品质与灌浆材料固化物性能。为了明确2种材料长期接触的相容性,在模拟工况下开展原油静态浸泡试验,比较试验前后原油的元素含量与环氧固化物的质量、强度、分子结构、表面形貌等变化。结果表明:在40 ℃条件下,原油成分未发生显著变化,未对环氧树脂固化物的力学性能及结构形貌产生不利影响,二者间未发生化学反应。判断在正常运行条件下,原油与环氧树脂灌浆材料具有较好的相容性。
Abstract
The compatibility between crude oil stored in underground water-sealed cavern and epoxy resin grouting material used for anti-seepage is defined as follows: the quality of crude oil and the mechanical properties of epoxy resin grouting material may change after long-term contact between the two organic materials. Static immersion test in crude oil was designed under simulated conditions to compare the changes of characteristic element content of crude oil and the quality, strength, molecular structure and surface morphology of epoxy resin cured materials before and after the immersion test. Results show that the composition of crude oil did not change significantly, nor did it adversely affect the mechanical properties and structural morphology of epoxy resin cured materials at 40 ℃. No chemical reaction occurred. It is concluded that the crude oil has good compatibility with epoxy resin grouting material under normal operating conditions.
