| Abstract: | Statistics show that the ineffectiveness of rigs in the oil fields in North Shaanxi is caused by great alternating stress on rigs. Considering rigs, drilling stress, rotating speed of rotary disks and the performance of drilling fluid, a good rig combination and craft has been chosen to lower the rate of ineffectiveness accident. |
