摘　　要：常规氮气钻井技术主要用于气井储层钻进,以防止由于空气钻井带来的高风险,但不适用于浅层气藏。为了提高葡萄花油层勘探开发效果,保护储层,防止由于泥浆钻井带来的储层污染,大庆油田开展了柴油-氮气雾化工艺技术研究。该技术利用雾化钻井液携岩效率高,柴油可有效稀释原油等技术优势。通过自主研制小型旋转防喷器、专用安全丢手工具等,实现了储层的安全、高效施工,减少了后期开发成本。相比邻井提高了产量,达到了很好的应用效果。The conventional nitrogen drilling technology is mainly used in gas reservoir,for preven-ting the high risk brought air drilling.In order to improve the development effect of Putaohua for-mation,protect the reservoir and prevent the reservoir pollution caused by mud,Daqing oilfield carried out the technology of the diesel-nitrogen atomization,using the technical advantages of the atomized drilling fluid’s carrying rock better and diesel oil can dilute crude oil effectively,through developing a small RBOP and a special safety releasing tool independently,which built safely and efficiently,reduced the cost,increased the output compared to the adjacent wells,and achieved a great effect.
