摘　　要：VSP测井仪采用先进的光纤传感技术进行油气层测试.要保证其能准确的测试,推靠机构的设计至关重要.利用ADMAS 软件进行推靠机构的优化设计,选择对机构性能影响较大的部件尺寸作为设计变量,以推靠力作为目标函数建立优化模型.采用修正的Newton-Raphson 迭代算法进行仿真计算,既准确又提高设计效率.最后得出了优化设计方案,当井径在100～250 mm,推靠臂的长度为230 mm;当井径在250～400 mm,推靠臂的长度为383 mm;当井径在400～520 mm,推靠臂的长度为487 mm;最佳间距为42 mm;最佳水平推力为6 000 N.这种设计使仪器具有较大的工作范围,使VSP 仪器具有操作方便,节约能源,工作稳定等优点.VSP jogging tool adopts advanced fiber optics sensor to test the oil - gas reservoir. In order to measure accurately, it is important to design the eccentering machinery. A optimization mode was established by using ADMAS software to optimize design for occentering machinery, in which chose unit size affecting capability of machinery as variety and considered eccentering force as object function. Correcting Newton - Raphson method was adopted to simulate, which is not only accurate but also efficient. Finally optimization design project was offered. The results show that the length of eccentering arm is 230 mm when hole＇ s diameter is in the range from100 to 250 mm, the length of eceentering arm is 383 mm when hole＇s diameter is in the range from 250 to 400 mm, the length of eccentering arm is 487 mm when hole＇s diameter is in the range from 400 to 520 mm, the optimal interval distance is 42 mm and the optimal level force is 6 000 N. This design makes machinery have wide working range, making VSP jogging tool manipulate simply, save energy and work stably.
