| 中文摘要:随着鄂北大牛地气田的持续建产，水平井规模开发已成为气田开发的重点技术。但在水平井施工中，由于诸如地层岩性变化，可钻性差异大问题；泥岩稳定性问题；低破裂压力层段地层漏失问题等；钻井液润滑性和携岩性能和岩屑床清除问题；以及地层变化、尖灭使得突然钻遇泥岩、煤层，发生坍塌、掉块等不可控因素，对水平井钻井提速提效产生不利影响和困难。本文分析了影响水平井提速提效的瓶颈问题，提出较为完善的技术方案，从而实现水平井施工安全、快速、高效钻进的目的。 |

| Abstract:Along with the sustainable construction and production in Daniudi gas field in Northern Erdos work area, the large scale application has become the major technology in gas field development. But because of the unfavorable factors of lithological changes, rock drillability differences, instability of mud stone and leakage in light fracture and low pressure reservoir; the uncertain factors of lubrication performance of drilling fluid, cuttings carrying capacity and the removal of cutting bed; as well as the collapsing block-falling in drilled mudstone coal seam and some others, there were still many difficulties to improve the drilling efficiency. Based on the systematically analysis on these bottlenecks, the technical schemes were put forward. |
