| 摘 要： | 总结了川东地区早期充气钻井试验存在的问题,结合充气钻井技术的特点,将充气钻井防漏治漏技术分为地层水压力系数小于漏层压力系数、地层水压力系数大于漏层压力系数两种情况,并根据每种情况提出了适合于川东地区的充气钻井防漏治漏技术方案,改进了充气钻井工艺.通过宝001-1、罐005- H2、温泉002-H2等井现场试验表明,该技术解决了川东地区地层出水与恶性井漏同时存在情况下的防漏治漏问题,减少了因井漏造成的处理复杂时间,提高了机械钻速,缩短了钻井周期,节约了钻井成本,经济效益明显.基于充气钻井的防漏治漏技术已在川东地区现场试验多口井,效果良好,建议大面积推广使用.

| Abstract: | The existent problems in aerating drilling early test were summarized in East Sichuan region. Based on the characteristics of aerating drilling,the preventing lost circulation technology was divided into two status,that is the formation water pressure coefficient is less than leak layer water pressure coefficient,and formation water pressure coefficient is greater than the leakage pressure coefficient. According to every case,the programs of preventing lost circulation suited for East Sichuan area were prop... |
