| Abstract: | A clay free drilling fluid system was constructed by using NaCl/KCl/HCOONa as the basic liquid phase of drilling fluid,self-developed polymer VIS-B as flow pattern regulator,acid soluble modified starch sta as fluid loss reducer,Dua and Jqw as temporary plugging materials.The system is stable and adjustable in the density of 1.101.28 g/cm^3,and the temperature resistance can reach 130℃.It has high low shear rate viscosity and good lubrication performance,and can effectively resist the pollution of various reservoir pollutants,fully meeting the operation requirements of different reservoir sections in missan oilfield. |
