Abstract
In order to address the issues of low efficiency,poor accuracy,and high cost associated with traditional layered testing techniques in injection wells in oilfields,a new technology based on the advancement of digital intelligence in oilfields was studied.This technology integrates intelligent pipe string measurement and adjustment techniques,prefabricated cables,intelligent water distributors,and intelligent packers,achieving automation and intelligence in the layered testing process of injection wells.By utilizing the multifunctional devices composed of intelligent pipe strings,real-time monitoring and collection of geological data can be realized.Through visualization interfaces,the testing data were displayed,which enhances the visualization degree of data analysis and management.Through remote control,real-time detection and resetting of injection rates for each layer,viewing of pressure and temperature in injection layers,and conducting packer sealing tests can be performed.In addition,the intelligent calibration self-checking instrument at the wellhead can periodically recalibrate and calibrate the parameters of downhole instruments.This technology provides a new idea and direction for the application of intelligent testing technology in oilfield industry.
