Desc:With the advancement of drilling technology, the drilling speed is accelerated, and the requirements for drilling fluid are more precise. Viscosity is related to the safety factor of construction. The effect of pressure on the apparent viscosity at room temperature is indeed great, but as the temperature increases, the effect of pressure on the apparent viscosity gradually decreases. When drilling into deep formations, the effect of temperature on the apparent viscosity of drilling fluid significantly exceeds the effect of pressure. Potassium formate drilling fluid is currently widely used drilling fluid system.
