旋冲钻井技术在十屋30井的应用

Application of Rotary Percussion Drilling Technology in SW30 Well

摘要:

长岭断陷深层地层岩石可钻性级值高，机械钻速低，钻井周期长,严重影响油气勘探速度，提高深部地层钻井速度已成为该地区亟待解决的问题。分析了旋冲钻井高效破岩原理，介绍了十屋30井开展旋冲钻井提速情况，为今后开展相关的研究及提速实验提供了借鉴。

Abstract:

The high drillability grade, low penetration rate and long drilling cycle seriously affect the exploration speed in Changling deep fault depression. Analysis was made on the principle of efficient rock-breaking by rotary percussion drilling and the exploration speed improving situation.
