摘要
通过对某工程发生钻具隐埋在107m水深的孔底的案例分析,分别介绍了事故发生时所采取的措施、分析事故发生的最直接的原因以及所采用过的打捞方法—气动锤振动法、高压注水法和小钻头清渣法,并将这3种方法在打捞中所起的作用及其适用范围作了分析和比较。
According to analysis of an accident of drilling tools which were buried in the bottom of a 107 meters deep pore, authors introduce measures adopted in this accident, direct reasons causing this accident, and three adopted fishing methods, which are air-vibrate hammer method, high-pressure water method, and the small drill head cleaning cinder method. Authors also analyze and compare actions and application scopes of these three methods in this fishing process.
