摘要:
为满足导向钻井中不用起钻变更钻具组合,就能快速钻出高质量的井眼轨迹的客观要求,提出了一种由单片机控制调频调压的供电模块设计方案。该方案与现阶段钻井导向系统中常用的由可调元器件构成的三端稳压电源所实现的供电模块、以及利用IGBT绝缘栅双极型晶体管的双向导电功能实现的供电模块不同在于,它采用单片机AT89C5控制调频调压主电路,结合桥式逆变电路,通过IR2110驱动实现调频,并设计过电流(压)保护。测试结果表明,依据该方案所实现的供电模块设计原理简单、控制可靠、成本低廉,能满足钻井导向系统在各类工况下供电模块应用要求。

Abstract: To meet the requirement for fast drilling of a high quality well trajectory without tripping for changing the BHA (bottom hole assembly) in steerable drilling, a program was proposed for de-signing power supply module for frequency and voltage controlling with a single chip computer. Compared with power supply module realized by the three terminal voltage stabilized power supply composed of an adjustable component and power supply module realized by using IGBT (insulated gate bipolar transistor) with bidirectional conduction function, which are the most commonly used in the present stage, what makes the program different is that it utilize single chip computer AT89C5 to control the main circuit of frequency and voltage adjustment, combined with a bridge inverter circuit, implementing the frequency adjustment through IR2110 driving, and de-sign over-current (voltage) protection at last. The testing result shows that the module design based on the program is simple and controllable, it can meet the demands of applications of the power supply module of the drilling system under various working conditions.
