Design of Turbine Generator Test System for Downhole Drilling Instrumentation
In oil logging instruments with drilling,turbine generators must undergo rigorous reliability testing before they can be applied to downhole logging instruments.Conventional water cycle test method has the problems of the bulky test equipment,high test cost and high time-consuming and laborious.A turbine generator on-line test system is designed.A motor-to-drag generator is used to rotate the turbine generator.By changing the rotational speed of the motor,the downhole mud flow condition environment with different compositions and densities is conveniently simulated.The output power is rectified and filtered into the adjustable electronic load module,to measure the generator's power generation capacity and complete the turbine generator body output capacity test and reliability test.Test results prove that the system is simple to operate,convenient and practical,and reduces the development cycle and development cost of the instrument.The system has been successfully applied to the development and testing of drilling instruments,which is of guiding significance to the design and improvement of the turbine generator body in the future.
