国内水平井用油基钻井液普遍存在切力低、流变性能差和后续钻屑处理难度大等问题，在性能和环保方面均需要完善。为满足绿色高性能钻井液的发展需求，以天然来源的植物油为原料，采用生物和化学改性的方式，合成了一种性能优异、可生物降解的生物质基液PO-12。性能测试表明，PO-12具有黏温特性优良、稳定性好、抑制性强、抗水解和无荧光的特点，其结构中不含芳香基团，无毒，绿色环保，能够满足水平井和深海钻井需求。以PO-12为连续相，初步形成一种生物质合成基钻井液，性能与油基钻井液相当，为提高水平井用钻井液的绿色环保性能提供了一种新的途径。

Oil-based drilling fluids deployed for drilling of used in horizontal well drillings in China are characterized by their low shear strength,poor rheological properties and difficulty in subsequent treatment of cuttings disposal. Under such circumstances,it is necessary to improve their performance and environmental protection features. To meet the demands related to the development of environment-friendly high-performance drilling fluids,natural vegetable oil was used to generate a biomass-based liquid,PO-12,through biologic and chemical modification. Test results showed that the biodegradable PO-12 has outstanding performances in viscosity,heat resistance,stability,inhibition,hydrolysis resistance and fluorescence. With no aromatic compositions and being non-toxic,the environment-friendly PO-12 can satisfy the demand of for drilling of horizontal wells drilling and offshore operations. On the basis of the PO-12,a biomass synthetic drilling fluid system has been developed. With performance equivalent to that of oil-based drilling fluids,the innovative system may provide a new way to enhance environmental protection performances of oil-based drilling fluid systems.
