下面这段中文，希望网友帮忙译为英语：第一次开钻钻进：2009年12月31日22：00使用26&钻头、搬土聚合物钻井液自园井深16.40m第一次开钻，2010年1月4日06：00钻进至井深262.5m，层位Upper.fars组第一次完钻，1月5日电测完，6日04：00下20&套管至井深261.50m固井，水泥浆返至地面，水泥塞面井深248.50m，套管清水试压10.0MPa合格，1月8日电测固井质量完，10日20：00钻水泥塞完，结束一开工作。

So, some countermeasures should be taken. New drilling technologies will be introduced including wash boring and micro -foam drilling. High-calcium salt polymer drill fluid with strong inhabit will be used in drilling, whose density should be adjusted according to the situation. Bore frame should be adjusted, that is to say, the pressure has few differences at one whole barefoot interval and density of the drill fluid should be big enough before drilling.

对此，提出如下治理对策：采用新的钻井工艺，引进清水强钻和微泡沫钻并技术；钻井中使用强抑制性高钙盐聚合物钻井液，并合理调整其密度大小；调整井身结构，在一个裸眼井段内不能有压力悬殊的地层存在，在揭开储层前，应适当提高钻井液密度。

At present, there are drilling more than 150 plants, with an annual output of various drilling about 1 million units, export over 20 million units, the drilling of speed through a pulley shift to resolve the pagoda, the governor need to stop the process, open the protective Enclosures, manual transmission, and other procedures, the process cumbersome and poor security, and is governing, not transferred to the spindle speed corresponding to the different materials of various aperture drilling at the best speed, the production efficiency is low.

目前，全国有钻床厂150多家，年产各种钻床100万台左右，出口20多万台，这些钻床的变速都是通过一对宝塔皮带轮换档解决的，调速过程需要停车、打开防护罩，手工换档等程序，操作过程繁琐且安全性差，并且是有级调速，不易使主轴转速调到对应于不同材质的各种孔径钻削时的最佳转速，因此生产效率也低。
