| 英文摘要 | The rotary steering system can effectively speed up drilling, ensure higher security and improve the accuracy of the well trajectory control. It is one of the core equipment in the oil and gas industry, especially for the exploration in complex environments. The non-contact electric energy and signal transmission unit is an important part for the rotary guidance system to transmit electric energy and signals from the rotating spindle to the non-rotating outer sleeve. In order to guarantee the stability of voltage output and the reliability of signal synchronous transmission under high temperature environment with heavy load, a transmission method is proposed where electric energy and signals can be integrated via carrier modulation. Based on the synchronous transmission topology with parallel injected and parallel pickup signals, isolation inductance and resonant capacitor are added to mathematically model the new topology and simulate the voltage gain, the current gain and the efficiency. According to the results, the optimal circuit parameters are selected. The experiments verify that the load can reach 150 W at the temperature of 175 degrees C by adopting this circuit topology and transmission method. Within the range of 150 W dynamic load, the change of the output voltage is less than 8% of the input voltage with a 115200 bps transmission rate, whose bit error rate is less than one millionth. |
