经大量小口径金刚石钻进证明,泥浆护孔有许多优越性。它除了可以对付连续作业出现的孔壁不稳定保证安全钻进以外,还可以在高转速钻进中对钻具起到减摩润滑的作用。
After a large number of small-diameter diamond drilling proved, mud hole protection has many advantages. In addition to the safe operation of the borehole wall for continuous operation, it also functions as a friction-reducing lubricant for high-speed drilling.
