Pearldrill Drilling Rig And Drill bits

  How to determine if the drilling fluid needs to be replaced or treated: Excessive change in density:  too high a density will increase the load on the drilling pump and even cause damage to the drilling rig; too low a density may lead to a blowout. High or low viscosity:  High viscosity affects the fluidity of the mud and the ability to carry rock cuttings; low viscosity does not effectively stabilize the well wall. High water loss rate:  High water loss rate will lead to thick mud cake, which will affect the drilling efficiency. Large amounts of cuttings or impurities in the mud:  This affects the performance of the mud and can cause the bit to clog. Deterioration or contamination of the mud:  For example, the mud has settled, fermented or become contaminated with chemicals.

  The use of coolant for water well drilling rigs has some similarities to the use of coolant for general drilling, but also has some unique considerations due to the special working environment and requirements of water well drilling rigs. The coolant used in water well drilling rigs is often referred to as “drilling fluid” or “mud”, and its function is not only cooling, but also includes carrying rock cuttings, stabilizing the wall of the well, and balancing formation pressure. The following is a detailed explanation of how to use water well drilling rig coolant correctly: 1. Main functions of drilling fluid: Cooling and lubricating the drill bit:  Reducing the temperature of the drill bit and drill pipe, reducing wear and prolonging service life. Carrying rock cuttings:  Bringing the rock cuttings generated during the drilling process from the bottom of the well to the surface, preventing the accumulation of rock cuttings from clogging the drill bit and the bottom of t...

  Water well drilling rigs loose parts contain a very large number of components, depending on the type and size of the rig, the specific configuration will vary. But generally speaking, its main components can be summarized as follows: 1. Host part: This is the core part of the drilling rig, mainly including: Power system: Diesel engine/electric motor:  provides the power source for the operation of the drilling rig. Diesel engine is commonly used in field operation, while the electric motor is suitable for places with power supply. Transmission system:  including clutch, gearbox, reducer, etc., used to transfer and regulate the power output. Rotary System: Rotor/Power Head: Drive the drill pipe and drill bit to rotate and break the rock. The power head is usually hydraulically driven, which can realize stepless speed change and large torque output. Vertical shaft/spindle:  Connects the rotator with the drill pipe and transmits the rotary motion. Feed system: Feed m...

  Toothed Wheel Bit, also known as Toothed Wheel Bit or Triple Toothed Wheel Bit, is a rotary drilling tool that is widely used in the fields of oil and natural gas exploration and extraction. Its main feature lies in the use of tapered tines as cutting elements to break rock by rotation and pressure. The following are the main structural features of the tooth wheel drill bit: 1. Tooth wheel (Cone): Quantity: The most common is the three-tooth wheel drill bit, there are also single, double and multi-tooth wheel drill bits, but the application is less. Three-tooth wheel drill is well balanced and has high drilling efficiency. Shape: The tooth wheel is tapered and its surface is covered with cutting teeth. The tapered design allows the tines to roll and break rock as they rotate. Bearing: The tooth wheel is mounted on the bit body through the bearing, the type and quality of the bearing directly affects the service life of the bit. Common bearing types are: Friction Bearing: Simple s...

  Adjust the core principle of the slurry pump impeller: adjust the clearance between the impeller and the front guard plate (or front and rear sheath) to ensure the efficiency and life of the pump. Too large a gap is low efficiency, too small a gap is easy to wear. 1. vertical slurry pump: Loosen the compression bolt of the bearing assembly. Unscrew the adjusting bolt to move the bearing assembly forward while manually rotating the shaft in the direction of pump rotation until the impeller slightly touches the front guard plate. (Rubber-lined pump) Measure the clearance between the impeller and the front and rear sheaths separately, and take half of the distance moved by the bearing assembly as the clearance value. Use the adjusting bolt to precisely adjust the clearance to the specified value (metal liner 0.5-1mm, rubber liner front and rear sheath clearance is equal). Tighten the compression bolt of the bearing assembly. 2. Center-open slurry pump: Factory has been adjusted, gen...
