摘　　要：浅层气井钻井施工中常发生井喷事故,引发着火、井眼垮塌、钻具遇卡或井眼报废,甚至因井喷导致地表坍陷、钻机被埋,还会对环境造成破坏和污染。根据地层情况,完善并制定了一套切实可行的钻井液技术方案和工艺措施,确保了浅层气井钻井施工安全。钻井实践表明,采用的浅层气井钻井液技术,达到了安全钻探目的。In shallow gas drilling,well blowout frequently happened,causing fires,bore hole collapse,pipe sticking,well/rig abandonment,and environmental pollution.Based on the analyses of the formation properties,a drilling fluid program and operational techniques were built to ensure the shallow gas drilling to be safe and smooth.Drilling practices showed that the drilling fluid program and the techniques were successful for use in Huabei oilfield.
