【摘要】：烷基糖苷作為一種性能優(yōu)良的綠色環(huán)保型表面活性劑,具有良好的乳化效果,是一種可以作為鉆井液乳化劑的表面活性劑。而且由于其優(yōu)良的性能及綠色環(huán)保的性質(zhì),是一種可以在未來得到廣泛應(yīng)用的表面活性劑。本文通過對不同碳鏈長度的烷基糖苷進(jìn)行了合成與性能評價(jià),并配制了一種性能優(yōu)良的水包油型乳化鉆井液。本次實(shí)驗(yàn)利用分步法進(jìn)行了不同碳鏈長度的烷基糖苷的合成,確定了最佳的反應(yīng)條件:正丁醇與葡萄糖摩爾比為6:1;使用質(zhì)量比為2:1的對甲苯磺酸與濃硫酸二元酸為催化劑,加量為葡萄糖質(zhì)量的1%;脂肪醇與葡萄糖的摩爾比為2:1;兩步反應(yīng)的反應(yīng)時(shí)間分別為2h和2.5h。最終烷基糖苷產(chǎn)物中殘余脂肪醇質(zhì)量為35%~40%,具有最佳的乳化效果及乳化穩(wěn)定性。并確定了乳化能力及穩(wěn)定性能最佳的烷基糖苷為十二烷基糖苷與司盤-20以7:3的質(zhì)量比復(fù)配而成的乳化劑。通過實(shí)驗(yàn)篩選出的水包油型鉆井液配方為:60%白油+40%水+3%復(fù)配乳化劑+0.5%增粘劑羥乙基纖維素(HEC)+0.3%降濾失劑羥丙基淀粉(HPS)。該鉆井液抗溫達(dá)120℃,具有良好的抵抗土侵、原油侵、鹽侵的性能。
[Abstract]:As a kind of green environmental protection surfactant with excellent properties, alkyl glycoside has good emulsifying effect and can be used as emulsifier of drilling fluid.Because of its excellent performance and environmental protection, it is a kind of surfactant which can be widely used in the future.In this paper, alkyl glycosides with different carbon chain lengths were synthesized and evaluated, and an oil-in-water emulsified drilling fluid with excellent performance was prepared.In this experiment, alkyl glycosides of different carbon chain lengths were synthesized by stepwise method. The optimum reaction conditions were determined: the molar ratio of n-butanol to glucose was 6: 1, and the catalyst was p-toluenesulfonic acid and concentrated sulphuric acid with a mass ratio of 2:1.The molar ratio of fatty alcohol to glucose is 2: 1, and the reaction time is 2 h and 2.5 h, respectively.The residual fatty alcohol in the final alkyl glycoside product is 35% and 40%, which has the best emulsifying effect and emulsifying stability.The optimum emulsifying ability and stability of alkyl glycoside was determined as the emulsifier composed of dodecyl glucoside and Span-20 at 7:3 mass ratio.The formula of oil-in-water drilling fluid selected from the experiment is as follows: 1: 60% white oil 40% water 3% compound emulsifier 0.5% viscosity enhancer hydroxyethyl cellulose (HEC) 0.3% filtrate reducer hydroxypropyl starch (HPSP).The drilling fluid has good resistance to soil invasion, crude oil invasion and salt invasion with temperature up to 120 鈩，
