摘　　要：辽河油田经过多年开发,多数油区地层压力逐年呈降低趋势,易发生井漏、井塌及卡钻等事故,完井固井阶段常出现水泥浆低返,储层伤害等问题。利用气体钻井技术,能够克服上述问题并且最大限度地提高潜山油气藏机械钻速,保护油气藏,降低钻井成本。对辽河油田适于采用气体钻井的潜山储层进行了深入分析,为提高辽河油田潜山油藏勘探开发效果提供了依据。After years of development, the formation pressure of the most oil regions in Liaohe Oilfield reduces year by year, and the accidents such as mud loss,borehole collapse and drill pipe sticking, as well as low cement slurry, return ratio in well cementing and reservoir damage etc. often occur. By applying the gas drilling technology, these problems can be solved, and the mechanical drilling speed in the buried-hill reservoir can be increased, the reservoir ean be protected and the well-drilling cost can be reduced to maxi- mum extent. The applicability of gas drilling to the buried-hill reservoir in Liaohe Oilficld is deeply analyzed to provide a foundation for improving the exploration resuh of the buried-hill reservoir.
