| 摘 要： | 通过理论研究和现场试验,以国内现有钻井装备条件为基础,形成了包括井眼轨迹控制技术、电磁波随钻测量技术、无固相钻井液技术和欠平衡钻井技术的长水平段水平井钻井配套技术,并在大牛地气田DP4、DP5、DP6等3口井进行了应用.实践表明,充气全过程欠平衡钻井技术提高了大牛地气田机械钻速,达到了在钻井过程中保护油气层、及时发现油气层和提高单井产量的目的.总结了长水平段水平井井眼轨迹控制的基本方法,提出了其他相关技术的发展建议,对于高效开发低孔低渗油气田具有重要的指导作用.

| Abstract: | The technology developed through theoretical study and field tests based on available drilling equipment for drilling long horizontal section includes well trajectory control,electromagnetic wave MWD,solid free drilling fluid,and underbalanced drilling techniques. Field application of these techniques in Well DP4,DP5 and DP6 of Daniudi gas field shows that the rate of penetration has been greatly improved by using underbalanced drilling technique by aeration for the whole process,the reservoirs are protecte... |
