Technology Research and Design on The New Device of Drilling Fluid Mixing

In the process of oil and nature gas drilling, the drilling fluid density is a very important parameter, which is one of the key factors of drilling safety. In the drilling process it is important to adjust the drilling fluid density rapidly according to the formation pressure. However, the efficiency of existed adjustment device of drilling fluid density mixing is low, slow and unstable for the need of drilling fluid. In this paper, the finite element simulation and structure design were carried out to study the new device of drilling fluid mixing which includes fluidic element, mixing chamber and outlet pipe. The experiment results show that the new device has the advantages of high efficiency, small size and good maneuverability.
