井喷失控是钻井中的灾难性事故，有必要开展井喷失控研究，找到井喷失控发生的原因和提出防止井喷失控的对策。在统计分析1970年到2009年间中石油发生在钻进过程中的48例井喷失控事故的基础上，通过对防喷器、节流压井管汇、套管、井喷后爆炸起火等井喷失控因素分析，并利用 MLS 法对上述各种井喷失控因素危险值进行评估。最后，根据井喷失控因素分析和危险值评估结果，结合现有的钻井井控设计，提出了防止钻井井喷失控的对策。

Uncontrolled blowout is the catastrophic accident in drilling engineering .Therefore it is necessary to car-ry out the research on uncontrolled blowout , so as to find the reasons of uncontrolled blowout and propose the pre -venting countermeasures.48 cases of uncontrolled blowout accident occurred in the drilling process during 1970 to 2009 were summarized and analyzed .Through the analysis on the factors which caused uncontrolled blowout , such as BOP, kill manifold, throttle manifold, casing andexplosion and fire after blowout , the MLS method was applied to access their risk values.The factors which induced uncontrolled blowout were found out , and an evaluation method was developed to access the risk valuesof uncontrolled blowout factor .Finally some countermeasures to pre-vent drilling uncontrolled blowout were put forward .
