The importance of the drilling rig mud drilling fluid plays an important role in the drilling industry, it can be regarded as the drilling of blood. Common drilling fluid is generally divided into water, mud, clay-free fluid phase, emulsion, foam and compressed air, etc., through practice that the role of the drilling fluid following main points: 1, cleaning, lubrication, cooling drilling Machine bit; 2, clean bottom, carrying debris and assisted rock; 3, balancing rock wall side pressure multi-function rig factory closure and borehole stability; 4, can pass the required power downhole drill motor and drill water power; 5, to reduce cuttings sedimentation rate, avoid heavy Shaka drill; 6, drilling of drill and casing buoyancy, can be reduced from tripping when load lift system. Drilling fluid displacement in general, the size of the pressure, and the choice of water, mud or emulsion and so have a huge impact on the cleanout effect. Capacity increases displacement, bottom cleaning drill cuttings and cooling increases, clean the bottom can not only improve the rate of penetration and bit of wear and tear can be reduced. But drilling fluids used in the process according to the provisions in certain operations, but also to understand some of the negative effects, or else would be counterproductive. Note 1 rig blast, blasting load running-rig shall not be less than 20 minutes. 2, from the tower must be "from the tower" handle slowly into operation "up", "down" direction. 3, to observe and control the oil level, keeping the oil is always in between the upper and lower limit position to avoid loops into the air, the cooling effect is reduced, affecting the efficiency and lifetime and performance rig hydraulic components. 4, attention always observe the conditions of each element works well drilling rig hydraulic system to ensure no leakage passage closed, tubing and moving parts without friction, pulling, hanging and folded over the limit. 5, there is a system pressure control valve, the factory has been adjusted, under normal circumstances not be adjusted on the two joint operations longitudinal valve. 6, loading, unloading drill pipe must accurately confirm the "forward", "reverse" position after the rig, correct manipulation "rotation" handle, while the operator is in a safe position must be correct drilling rig construction, to avoid accidents. 7, rig positioning must firmly installed, so beware of torque roll or big rig to rig shifted into force of the accident or hole deviation. 8, the site of poor environmental conditions, clean the hydraulic oil should attach great importance, such as refueling drums, hands should be clean, after you add oil to seal the tank cover.
