| Abstract: | The formation dynamic tester gradually becomes an indispensable equipment in the field of petroleum exploration and development. The operation stability of hydraulic system can be easily destroyed by the harsh downhole environment. Therefore, it is urgent to discover its potential defects through simulation and provide corresponding optimization methods. Firstly, the hydraulic system composition of formation dynamic tester is introduced, as well as its working principle and dynamic characteristics. Secondly, the simulation model is established in Automation Studio, and the parameters are set up according to the realistic situations. Then totally eight kinds of working states are considered to obtain several important parameters, such as output pressure of pump, actuators displacement. Based on these results, the potential defects are analyzed and corresponding optimization design scheme is proposed. |
