摘要： An annular safety valve sealing package that is suitable for use in the presence of an acid gas and that is capable of retaining its material properties when the annular safety valve is retrieved is provided. The annular safety valve sealing package includes an annular safety valve having a tubular housing, a first annular sealing element including a first elastomeric material and disposed about the tubular housing, a second annular sealing element including a second elastomeric material and disposed about the tubular housing, and a third annular sealing element including a third elastomeric material and disposed about the tubular housing on an opposite side of the second annular sealing element from the first annular sealing element. At least two of the first elastomeric material, the second elastomeric material, or the third elastomeric material have different compositions.
