1) two center orbital
双心轨道
2) twin-core
双心
3) bicenter bit
双心钻头
1.
When drilling with bicenter bits, several problems have been encountered, such as drilling a smaller- than - expected hole, the instability of bottom hole assembly (BHA), and hole deviation tendencies that make the bit extremely weight sensitive.
针对使用双心钻头钻进时扩孔尺寸不理想、钻具工作不稳定、井斜趋势引起钻头工况对钻压非常敏感等问题,对底部钻具组合的受力、变形和运动状态等方面进行了分析研究表明,由于双心钻头几何设计的独特性,工作时钻头上受有不平衡力,这使得钻头切削不稳定,且影响钻柱变形。

补充资料:双心室辅助泵装置
双心室辅助泵装置
double ventricular assisted blood pump set,direct mechanical ventricular assistance,DMVA
是一种以机械力量直接挤压心脏使心脏泵血的设备。包括辅助杯、驱动器和负压固定装置。辅助杯形状与心室相同,杯的尖部和侧壁各有一个接管口,外壳用玻璃制成,内衬一层硅橡胶薄膜,其上、下两端分别黏接于杯口边缘下数毫米和杯尖部,使薄膜与杯体内壁形成内气囊。杯口有一个同心圆形硅橡胶软边,起封闭及右室流出道限压作用。使用时,将杯尖部接管接负压,使杯固定于心室上,而侧接管接驱动器,由驱动器产生正负压使心室相应被挤压和舒张。
