PESA与EDTMP复配剂用于油田硫酸钡锶垢阻垢的研究
|
摘要
本文研究发现,PESA(聚环氧琥珀酸盐)对硫酸钡垢阻垢效果显著,EDTMP(乙二胺四亚甲基膦酸盐)对硫酸锶阻垢效果明显,将PESA与EDTMP按质量进行配比,对硫酸锶垢阻垢存在明显协同增效作用。PESA属生物可降解产品,目前市场价格较高;EDTMP价格偏低,属膦系产品,应用上存在环保问题。以我国某海上油田矿化水组成为例,从阻垢性、环保性以及产品应用经济性三方面,对PESA和EDTMP复配剂作为油田硫酸钡锶垢阻垢剂进行了探讨。
According to this research,PESA(polyepoxysuccinic acid) has excellent characteristics of inhibiting barium sulfate scale,while EDTMP(ethylene diamine tetramethylene phosphate)has characteristics of inhibiting strontium sulfate scale.When combining PESA and EDTMP in different ratio of weight,the synergistic effect of inhibition is very evident in inhibiting strontium sulfate scale.PESA has complete characteristics of biodegradation,however,the price of PESA is higher in comparing with other inhibitor using in oilfield. EDTMP contain phosphorus and would pollute environment,but the price of EDTMP is relatively low.This paper discussed the combination of PESA and EDTMP for inhibiting scale at offshore oil field W12-1 from points of efficiency of inhibition,ecology and economy.
