Application Progress of Synthetic-based Drilling Fluid in Oilfield Drilling
Synthetic-based drilling fluid has excellent operating performance similar to oil-based drilling fluid,meanwhile it also has obvious environmental advantages,including low biological toxicity and high biodegradability.Synthetic-based drilling fluid has been widely used in offshore drilling and other environmentally sensitive areas.The development process of synthetic-based drilling fluid has experienced from the first generation(ester,ether,poly α-olefin,acetal)to the second generation(linear alkylbenzene,linear paraffin,linear α-olefin,internal olefin).Each kind of drilling fuild system have its own characteristics and advantages.Currently,the widely used synthetic-based drilling fluids are mainly olefin base and alkane base.The development of F-T synthesis technology has provided gas-to-liquid(GTL)drilling fluid base oil,with Saraline 185V as the main product.GTL,which has the characteristics of low viscosity,good viscosity-temperature property and low toxicity,is the most advanced drilling fluid system at present.
