| 摘 要： | 在沉积岩钻探施工过程中,经常会遇到松散、破碎、坍塌、水敏性等复杂地层。过去的做法主要是使用水泥封孔和套管固井等方法,施工成本高、效率低、劳动强度大。无固相钻井液的出现和发展,为沉积岩钻探难题提供了有效的解决方案。通过几个应用实例,介绍了在无固相钻井液技术研究及其在沉积岩复杂地层中的应用效果。

| Abstract: | The loose,broken,collapsed and water-sensitive formations are often encountered while drilling in the sedimentary formations,which were mainly dealt with cement sealing and casing cementing in the past with high drilling cost,low efficiency and great labor intensity in the past.Along with the appearance and development of non-solid drilling fluid technology,effective solutions are provided to overcome difficulties in sedimentary rock drilling.The paper introduced the research on non-solid drilling fluid technology and its application effect in complex sedimentary formation drilling by application example. |
