伴随着新区块新领域的不断深入,新问题也会不断出现,尤其在各含油区块的石炭系地层,其可钻性非常差,机械钻速非常低.面对此难题,现场试验了一种可以提高机械钻速的工具-液力推力器.通过跟踪分析表明,该工具在一定程度上不但可以提高机械钻速,而且对整个钻柱起到了保护.如果液力推力器在本油田推广使用,将对新疆油田在石炭系地层的深入探油,起着积极推动的作用.

The drillabillity of carboniferous formations is very poor, and its drilling rate is very low in Xinjiang Zhunger Basin. Facing this difficulty, hydraulic thruster used for improving penetration rate was developed. This paper introduced the structure, working principle, application methods, and notice in application of hydraulic thruster. Through field application, the results showed that the tool could not only improve the penetration rate, but also protect the whole drill stem.
