摘要
The silicate drilling fluid system is an agent suppression fluid dominated by inorganic salt which is used to prevent collapse of borehole wall.It has the physical and chemical sealing,a double role of wall reinforce.It can effectively reduce the penetration of wall,and impede pressure transmission.And it has good rheological properties,is non-toxic,non-fluorescent,low cost,considered with the development prospects of one of the water-based drilling fluids.In the Carbonaceous mudstone areas,drilling frequently encounters some problems,such as loss,collapse,block falling down,and water inflow,bringing about a great trouble to the safety of drilling.
