| 摘 要： | 甘肃肃北县金鹰矿区ZK1146井是在甘肃祁连山金矿实施的一口科学钻探井，矿区地层包括砂岩、泥岩、炭质板岩和千枚岩。地层成岩性、胶结性差，倾角大，层理紊乱，井壁强度低。针对现场情况，研制了成膜防塌无固相钻井液体系。该体系主要是针对破碎、坍塌掉块及水敏性地层的钻进施工中遇到的主要难题，具有护壁性、抑制性和胶结性。通过在ZK1146井中的应用，取得了较好的护壁、护心效果，有效地防止了泥岩的分散，保证了该项目的顺利施工。

| Abstract: | Well ZK1146 is a scientific drilling hole for Qilianshan gold mine, which is located in Jinying mining area of Gansu Province; the mining area contains formations of sandstone, mudstone, carbonaceous slate and phyllite with poor lithology and cementation, large dip angle, disordered bedding and low wall strength. Based on this situation, the solid free film-forming and anti-sloughing drilling fluid system was developed with inhibitory and cementation to solve the drilling difficulties in broken, collapse and water sensitive formations. Good effects of borehole wall and core protection have been obtained in well ZK1146, the mudstone dispersing is effectively prevented. |
