| 中文摘要:鄂尔多斯盆地伊陕斜坡GHW2井是在陕西府谷庙沟门施工的一口页岩气探井，地层主要为千5、盒8、山西组、太原组、本溪组，钻进过程中坍塌掉块、破碎严重。针对现场破碎、坍塌掉块及水敏性地层钻探遇到的主要难题，研制了双聚防塌冲洗液体系。该体系具有护壁性、抑制性和胶结性。通过在GHW2井中的应用，取得了较好的护壁、护心效果，有效地保证了该项目的顺利施工。 |

| Abstract:GHW2 in Ordos basin is an exploration well for shale gas, serious collapsing, rock falling and breaking occurred in the drilling process. According to these conditions, bi-polymer anti-caving fluid system was developed, which has wall protection, inhibitory and cementation properties, and is mainly aiming at the main difficulties encountered in drilling construction in breaking, collapsing, block falling and water sensitive formations. This system was applied in GHW2 with good effects of wall protection and core integrity. |
