摘要
统计资料表明,陕北油田钻具失效的主要原因是钻具在井下承受的交变应力较大。从钻具、钻压和转盘转速、钻井液性能等方面优选了适合该地区安全钻进的钻具组合和工艺技术,从而降低了钻具失效事故的发生。
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.
