摘要
Abstract
At present,the shale gas exploration under the oil well still relies on the traditional magnetic locator and the winch cable connection.The CCL signal collected is unstable,and it is difficult to identify the collar signal.In order to solve this problem,a wireless perforating system applied to shale gas exploration in oil Wells is designed and developed.Based on the microprocessor STM32H735IGT6 of ARM Cortex M architecture,the system builds peripheral hardware circuit to realize the specified function.After collecting downhole CCL signals from the analog front board,the system passes through two amplifiers.Realize the function of signal attenuation and amplification,and output the signal to the wireless perforating control system.The master clock frequency is 400 MHz,the universal timer drives 16-bit ADC every millisecsecond to sample analog front-end signals,and stores the sampled data to the peripheral FLASH chip by means of"Ping pong cache"and DMA+SPI cache.A set of host computer serial port control program based on python is designed to realize the control of wireless perforating system.Including data processing,control sampling,perforation parameter import and other functions.The simulation results show that sampling collar signal and control storage meet the design requirements.关键词
