摘要
通过对埕北303井311.2mm、215.9mm井眼158.8mm钻铤多次断落井内及落鱼断口的外观检查,从钻具结构,钻铤弯曲强度比的计算等方面分析,探讨钻铤断落的原因,并提出钻具探伤方面应注意的问题,以避免今后同类事故的发生。
Abstract
By checking 158.8mm drill collar breaking in 311.2mm,215.9mm well bore many times and the appearance of fish breakpoint in Chengbei 303 well, analyzing drill tool structure and the calculation of drill collar bending strength ratio, the reason of drill collar breaking in hole is discussed. And the paper puts forward the problem of drill tool defecting detection, which will be avoided in the future similar situation.
Keywords:
drill collar;
fish;
bending strength ratio;
