  • 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.
