【摘要】：為了鑒別長(zhǎng)期風(fēng)化的沉底油,以1種原油(A)和2種燃油(B和C)為研究對(duì)象,采用重復(fù)性限法篩選340 d風(fēng)化的水面漂浮油和水下沉底油的穩(wěn)定診斷比,并基于這些診斷比對(duì)沉底油進(jìn)行聚類分析。結(jié)果表明,診斷比的穩(wěn)定性不僅和油種、風(fēng)化時(shí)間有關(guān),還和溢油的存在形態(tài)密切相關(guān);輕組分含量相對(duì)高的A和B的沉底油比它們對(duì)應(yīng)的漂浮油受到的風(fēng)化影響更大,而重組分含量高的C正好相反,研究最終得到4個(gè)適合鑒別長(zhǎng)期風(fēng)化漂浮油和沉底油的穩(wěn)定診斷比;聚類分析法可將沉底油與其油源很好地聚類,并可反映沉底油的風(fēng)化程度。因此,基于穩(wěn)定診斷比的聚類分析法可用于鑒別長(zhǎng)期風(fēng)化的沉底油,值得進(jìn)一步推廣。
[Abstract]:In order to identify long-term weathering of bottom oil, with 1 kinds of crude oil (A) and 2 kinds of fuel (B and C) as the research object, the repeatability limit method for screening 340 D weathered floating bottom oil and water stability under diagnosis ratio, and based on the clustering analysis of these diagnostic results. Comparison of bottom oil show that the diagnosis ratio and stability not only oil, weathering time, and oil spill forms are closely related; the weathering effect of floating oil content of light components with relatively high A and B than their corresponding bottom oil is larger, and the reorganization of the high content of C on the contrary, the research finally obtained 4 for the identification of long-term weathering and floating oil and bottom oil stability than the clustering analysis method can diagnose; oil and oil source will sink well cluster, and can reflect the degree of weathering of bottom oil. Therefore, stable diagnostic than cluster analysis method can be used for the identification of the bottom oil based on long-term weathering It is worth further promotion.
