| Abstract: | Technologic challenges of improving drilling speed in WuXia area of Junggar basin include:low drilling penetration rate in hard formation,borehole deviation,serious circulation loss,high risk of well blowout,etc.Therefor,a series of new drilling techniques to improve drilling speed in this area was experimentally used in recent years,including foam drilling,Nitrogen drilling,impregnated diamond bit +high speed turbine drilling,vertical drilling,etc,through using the above new techniques,the drilling penetration rate was improved significantly,the complex time was decreased obviously. |
