【摘要】：在石油勘探開發(fā)過程中,隨著開采的不斷深入,開采環(huán)境越來越復(fù)雜,開采效率越來越低。油氣井酸化可以顯著提高油氣采收率,但同時(shí)加劇了設(shè)備的腐蝕,為適應(yīng)這一現(xiàn)狀,開發(fā)油氣井酸化緩蝕劑非常迫切。介紹了國(guó)內(nèi)油田酸化緩蝕劑的研究現(xiàn)狀,主要從酸化緩蝕劑的種類、緩蝕機(jī)理、發(fā)展趨勢(shì)等方面進(jìn)行了闡述。對(duì)目前緩蝕效果良好并已廣泛應(yīng)用的曼尼希堿、咪唑啉類、季銨鹽型緩蝕劑做了重點(diǎn)闡述,從物理吸附、化學(xué)吸附、π鍵吸附三個(gè)方面研究了緩蝕劑的吸附機(jī)理,并從分子結(jié)構(gòu)出發(fā),分析了這幾類常用緩蝕劑的作用機(jī)理,同時(shí)對(duì)以后的研究工作提出了看法和建議。指出了今后酸化緩蝕劑的研究方向,是開發(fā)從天然物質(zhì)中提取,環(huán)境友好且耐高溫、耐濃酸的復(fù)合型長(zhǎng)效緩蝕劑。
[Abstract]:In the process of petroleum exploration and development, with the deepening of exploitation, the mining environment is becoming more and more complex, and the mining efficiency is becoming more and more low. Acidification of oil and gas wells can significantly improve oil and gas recovery, but at the same time, the corrosion of equipment is aggravated. In order to adapt to this situation, it is very urgent to develop acidizing corrosion inhibitor for oil and gas wells. This paper introduces the research status of acidizing corrosion inhibitors in oil fields in China, mainly from the aspects of types, mechanism and development trend of acidizing corrosion inhibitors. The adsorption mechanism of Mannich base, Imidazoline and quaternary ammonium salt corrosion inhibitor, which has good corrosion inhibition effect and has been widely used, has been studied from three aspects: physical adsorption, chemical adsorption and 蟺 bond adsorption. Based on the molecular structure, the mechanism of these kinds of corrosion inhibitors is analyzed, and some suggestions for further research are put forward. It is pointed out that the research direction of acidizing corrosion inhibitor in the future is to develop a compound long effect corrosion inhibitor which is extracted from natural materials, which is environmentally friendly and resistant to high temperature and strong acid.
