| 中文摘要:针对国家深部地质资源绿色勘查需求，以及地质特深孔复杂地层小环空条件下护壁难、冲洗液排放污染等难题，采用高温交联保护技术，研制了一套耐温150 ℃环保冲洗液体系。研究表明，该冲洗液经过150 ℃高温滚动后仍具有良好的流变性、降滤失性及页岩抑制性能，并具备较易降解（BOD5/CODCr值为21.5%）和经济性好的特点，在绿色勘查和环保要求严格的地质钻探中具有广阔的应用前景。 |

| Abstract:In view of green exploration requirements of national deep geological resources, difficulty in borehole wall protection due to small annulus in extra-deep geological drilling in complex formation, and pollution from waste drilling fluid, an environmentally-friendly high-temperature drilling fluid was developed using high temperature crosslinking and protection technology. Tests showed that after rolling at 150℃, the drilling fluid had good rheological properties, fluid loss reduction, shale expansion suppression, as well as easy degradation (BOD5/CODCr value of 21.5%) and cost-effectiveness. It has broad application prospects in green exploration and geological drilling where strict environmental protection requirements are exercised. |
