[Abstract]:A kind of ground tester based on miniaturized ground tester is developed. The equipment is a complete product of miniaturized formation tester. Its technical performance and index are designed according to the test function requirements of miniaturized formation tester. The equipment is an analog logging surface system, can be used as the electronic unit, hydraulic power, single detector function detection device in the miniaturized formation tester, for the repeatability, stability and reliability detection of the instrument, as well as trouble shooting. Equipment assembly, debugging and other links. In view of the practical problems encountered in the research and development process of miniaturized formation tester, and taking full account of the technical requirements of the petroleum industry, and drawing on the existing technology and experience both at home and abroad, the paper puts forward the overall plan at the same time. The system platform of the tester is developed from two aspects of hardware circuit and software design. The processing circuit of communication modulation and demodulation is developed. On the basis of modulation and demodulation, the program design of FPGA chip is completed, and the DTB three-bus logging communication is realized. In terms of software, a special software for performance testing based on miniaturized formation tester is developed, including signal acquisition, hydraulic control, data display and other functional modules of each module. Finally, the calibration and correction algorithms of strain pressure gauge, quartz crystal pressure gauge and pump pressure sensor are studied. The system structure is optimized and the performance of the instrument is improved. It provides technical support and testing means for improving the performance of miniaturized formation tester. And according to the actual engineering use and equipment stability requirements, completed the product finalization. The practical application shows that the developed system has good performance, meets the technical specifications and requirements of various items, and provides a good technical guarantee for the engineering use of the miniaturized formation tester, and has a good application prospect.
