What are the main components of drilling fluid?

• Drilling fluid is a mixture

• The drilling fluid consists of a dispersed medium, a dispersed phase, a drilling fluid treatment agent.

• The dispersing medium in drilling fluid can be water, oil, gas.

• The dispersed phase in drilling fluid, if suspended, is clay / density adjusting material; If it is an emulsion, it is oil water; If it is foam, it is gas.

Drilling fluid is a circulating flushing medium used in the drilling process. Drilling fluid is the blood of drilling, also known as drilling flushing fluid. Drilling fluid can be divided into clean water, mud, clay free flushing fluid, emulsion, foam compressed air according to composition. Clear water is the earliest drilling fluid used, which does require treatment is convenient to use. It is suitable for intact rock formations areas with sufficient water sources. Mud is a widely used drilling fluid, mainly suitable for unstable rock formations such as loose, fissured, prone to collapse block peeling, swelling peeling when encountering water。
