摘　　要：使用高级智能流变仪从微观角度评价了流型调节剂对油基钻井液性能的影响,并用高倍显微镜观察了油基钻井液的微观形貌。实验结果表明,常用的几种流型调节剂中,PF-MOVIS明显增加乳液的结构强度。随着PF-MOVIS的浓度增大,油基钻井液乳液的表观黏度升高,低剪切速率下黏度升高明显,屈服值上升。体系的弹性模量大于粘性模量,表明体系中形成较强的三维网络结构,与显微镜下观察乳液结构的增强相一致。The influence of rheology modifier in oil-base drilling fluid was evaluated by the modular compact rheometer and microscope.These results show that PF-MOVIS obvious increase the structural strength of the emulsion in several kinds of rheology modifier.Which also show the viscosity and yield value of oil-based drilling increased with the increase of the concentration of PF-MOVIS.Additionally,the elastic modulus is larger than viscous modulus indicating that strong three-dimensional network structure was formed in the system,which is consistent with the results of microscopic observation.
