Simulation Test on Wireless Radio Frequency Fracturing Sliding Sleeve System
When the wireless radio frequency identification(RFID)technology is applied in the fracturing of oil and water wells,the problems such as limited fracturing stages and non-intelligent operation of existing fracturing sleeve are well solved.However,the downhole conditions are complex,and there are some big differences between theoretical analysis and practical application.To further systematically explore the development and application of downhole wireless radio frequency system,a 3D software was used to design a wireless radio frequency sliding sleeve simulation test bench to conduct theoretical analysis on the labelled motion state.Then,a laboratory simula-tion test platform was built to conduct related downhole test.The test results show that selecting a ferrite core for the label and using a single-layer solenoid for antenna winding form can improve the performance of the whole system.Under the same inductance value of the system,the axial length of the single-layer solenoid antenna has a positive impact on the maximum passing speed of label that can be identified by the reader module.The angle between the label antenna coil and the reader antenna coil planes can also affect the identification rate of the label.The research results have certain guiding significance for the development and application of downhole wireless radio frequency system.
