| In order to further improve oil field of layered water injection well test efficiency and quality of the test measuring adjustable linkage layered water injection technology has been gradually extended to industrial application, to reduce the labor intensity, shorten test cycle and enhance the qualified rate of water injection.Downhole tune the controller design is to measure linkage hierarchical modulation technology based water distribution, and its main function is to achieve downhole data acquisition, processing and analysis and on the ground, generating test results and test the card table, and then give the corresponding control test results signal, adjusting the working status of downhole tools to change the water injection to improve water efficiency. Based on the understanding of the linkage hierarchical commissioning water distribution technology, based on in-depth study downhole tune the controller. Completed the first underground test tone controller hardware circuit design, and then through the lower computer software design, implementation downhole electromagnetic flowmeter data acquisition and processing, motor drive control functions, and the introduction of U disk storage and GPRS wireless communication technology, real-time information will be stored and transmitted downhole first bit machine. PC software to finalize the design of the controller in the data view, report generation and real-time control and other basic functions, based on the test software for the process of exposing a running non-adaptive made some improvements to upgrade programs, including instrument coefficient file encryption, file encryption data test results, the testing process monitoring and improving software operating mode.At last, through the field test results show that the design of the downhole measurement controller software, improve the detection precision of the borehole data, realize the adjustment of the layered water injection. And the related file is encrypted to ensure the security of data storage. At the same time, the updated software interface, the two big functions separate dispatch measurement and acquisition, through the working state of the software instructions, can test steps in operation, and effectively prevent the test data and collect data confusion. |
