[Abstract]:In order to further improve the test efficiency and test qualification rate of stratified water injection wells in oilfield, the technology of testing and regulating stratified water distribution has been gradually extended to the industrial application, which has achieved the purpose of reducing the test labor intensity, shortening the test period and increasing the qualified rate of water injection. The design of downhole testing and adjusting controller is the basis of the technology of stratified water distribution. Its main function is to realize downhole data acquisition, process and analyze on the ground, and generate test result table and test card. Then according to the test results, the corresponding control signals are given, and the working state of the downhole instruments is adjusted to change the water injection rate and improve the water injection efficiency. In this paper, the downhole monitoring and adjusting controller is studied on the basis of understanding the technology of stratified water distribution. The hardware circuit design of downhole measuring and adjusting controller is completed at first, and then the functions of data acquisition and processing of downhole electromagnetic Flowmeter, motor drive control and so on are realized through the design of lower computer software. The U disk storage and GPRS wireless communication technology are introduced to store and transmit the downhole information to the upper computer. Finally, the software design of the controller is completed. On the basis of the basic functions of data viewing, report generation and real-time control, some improvement and upgrade schemes are put forward for the inadaptability of the test software exposed during the running process. It mainly includes instrument coefficient file encryption, test result data file encryption, test process monitoring and improving software operation mode. Finally, the field test results show that the software designed in this paper can improve the precision of downhole data detection and realize the regulation of stratified water injection. And the relevant files are encrypted to ensure the safe storage of data. At the same time, the upgraded software interface will be independent of the two major functions of testing and acquisition, through the working state of the software instructions, can clarify the test operation steps, effectively prevent the confusion between test data and data collection.
