摘要

摘要: 生物质合成基钻井液被认为是替代油基钻井液且又能安全钻进的一类环保型钻井液。研究出一种生物质合成基钻井液用基液新材料--月桂醚LAE-12,其以月桂醇为原料通过一步法进行合成;对LAE-12的基本理化性质、黏温特性及抗水解性能进行评价,并与柴油、白油和生物柴油进行对比。结果表明,LAE-12的闪点、倾点、沸点、极压润滑系数依次为137℃、-13℃、289℃和0.039,表明LAE-12的安全、润滑性能优于柴油、白油;在0~90℃,LAE-12的黏温曲线变化较柴油、白油平缓,与生物柴油相当;在pH值为12的水溶液中,LAE-12具有强的抗水解性能,而生物柴油的水解率达72%;LAE-12配制的钻井液在油水比为8:2时,破乳电压大于600 V,动塑比在0.30 Pa/mPa·s以上,150℃下连续老化64 h,流变性基本无变化,室内效果与油基钻井液相当。

Abstract: Biomass synthetic base drilling fluid has been regarded as an environmentally friendly substitute for oil base drilling fluid.A base fluid for the biomass drilling fluid,LAE-12,a lauryl ether,has recently been developed through one-step synthesis using lauryl alcohol as raw material.Studies on the basic physio-chemical properties,viscosity characteristics and anti-hydrolysis performance of LAE-12 are conducted and comparisons of LAE-12 and other base fluids such as diesel oil,white oil and bio-diesel oil are done.The flash point,pour point,boiling point and extreme-pressure friction coefficient of LAE-12 are 137℃,-13℃,289℃,and 0.039,respectively,meaning that the safety and lubrication performances of LAE-12 are better than those of diesel oil and white oil.Changes of the viscosity of LAE-12 with temperature between 0℃ and 90℃ are much more gently than diesel oil and white oil,and are comparable to bio-diesel oil.In water with pH value of 12,LAE-12 is resistant to hydrolysis,while 72% of bio-diesel oil is hydrolyzed.Oil base drilling fluids formulated with LAE-12(O/W ratio=8:2) have emulsion stability of greater than 600 V,YP/PV of greater than 0.30 Pa/mPa·s,and stable rheology after ageing for 64 h at 150℃.In laboratory testing,the LAE-12 base drilling fluid has performance that is equivalent to oil base drilling fluid.
