FLUENT-based Study of the Configuration of Hydraulic Impactor

In view of the complicated configuration process of the dual-acting injection-type hydraulic impactor in the field application, the internal flow channel model and mathematical model of the hydraulic impactor are established by using FLUENT software. The working condition parameters of the test environment are used. Using the ICEM software, simulations are conducted to obtain the pressure distribution of the upper and lower chambers of the impactor, the velocity distribution and the velocity vector streamline of the fluid through the sucking element. FLUENT is used to carry out the application simulation of hydraulic impactor. By identifying the input parameters the same as the actual application and determining the flow state, the prediction of the tool operation can be realized. By changing the size of the suction element and adjusting the input and output parameters, the pre-analysis of the actual situation of the impactor with different specifications can be performed. By replacing the equipment with different specifications and the sucking element, the output parameters can be calculated according to the internal pressure and the distribution of the velocity, thereby providing references for the hydraulic impactor options identification in drilling different formations with different lithologies.
