Check Drilling Mud Tasks

Drilling mud is one of the most important components of rotary drilling, without which drilling is almost impossible. Drilling mud has many functions and applications, including cleaning the bottom of wells and transporting drilled debris to the ground, drying and lubrication of drilling tools such as drills, weight pipes and maintenance drilling pipes. From the wall of the well and create an impenetrable layer for the wall to prevent the entry of pressurized floors into the well to prevent the deposition of particles and weight-increasing materials of the drilling mud, while the drilling mud is stationary. Separation of drilled material after reaching the ground level Weight reduction of weight pipes, drill pipes and wall pipes according to Archimedes' law pointed to the hydraulic power of mud pumps to the drill. In this project, the goal is optimal hydraulic design for drilling mud. Due to the fact that in the optimal hydraulic design of drilling mud, the maximum hydraulic power and pump outlet pressure and well geometry are among the limitations, so the only parameters that can be used in the design are adjusting the pump outlet rate and size and number of drill nozzles. In this research, it was tried to design the optimal output rate as well as the number and size of drill nozzles to reduce the pressure drop and increase the hydraulic power of the pump.
