油页岩矿区地层结构复杂,钻孔施工中常有坍塌、掉块、缩径、钻井液漏失等现象发生,易造成埋钻、卡钻、烧钻等事故,且取心困难。通过综合分析并进行实验室试验研究,选择对御道口油页岩地层有较好抑制性的钻井液配方,在生产中选择正确的配制方法并保持好钻井液的性能。通过施工验证,取得了较好的施工效果和经济效益,并收集了大量经验数据,为今后在类似矿区钻探施工提供了技术支撑。
油頁巖礦區地層結構複雜,鑽孔施工中常有坍塌、掉塊、縮徑、鑽井液漏失等現象髮生,易造成埋鑽、卡鑽、燒鑽等事故,且取心睏難。通過綜閤分析併進行實驗室試驗研究,選擇對禦道口油頁巖地層有較好抑製性的鑽井液配方,在生產中選擇正確的配製方法併保持好鑽井液的性能。通過施工驗證,取得瞭較好的施工效果和經濟效益,併收集瞭大量經驗數據,為今後在類似礦區鑽探施工提供瞭技術支撐。

Because of the complex formation structure in oil shale mine, collapsing, block falling, diameter shrinkage and loss of drilling fluid often occur in the drilling operation, which make difficulties in core sampling with bit burying, sticking and burning.By the comprehensive analysis and experiments, the drilling fluid compound method with good inhabitation is selected for Yudaokou oil shale formation, the satisfied effects and ideal economic benefit are obtained, and a large amount of experimental data are collected to be technical reference for the drilling operation in similar mines.
