摘要

摘要: 针对钻井液易高温变性的特点，通过研制出耐高温增黏剂XCC、降滤失助剂AADC、封堵剂FSCC，设计出一种无固相抗220℃超高温的钻井液配方。具体加量配比为2% XCC+1% AADC+3% SPNH+1% SMP+3% FSCC+0.5% Na₂SO₃。并对其进行性能表征，SEM显示其页岩层状微裂缝及碎片得到了明显封堵与修饰，在泥页岩表面形成与微裂缝方向平行的致密树状聚合层；FT-IR结果表明，该抗高温钻井液经过220℃高温老化后性能稳定，具有良好的流变性能和滤失造壁性能，抑制和润滑性能满足钻井需要；能抗10%黏土与5%钻屑的污染，同时对10% KCl+20% NaCl的盐溶液也有较好的抵抗能力；该钻井液EC₅₀的检测结果大于80 000 mg/L，达到了建议排放标准。最终抗220℃超高温钻井液XCC/AADC/SPNH/SMP/FSCC在涩北1号气田24井得到了成功应用。

Abstract: A solid-free drilling fluid having stable properties at 220℃ has been developed with high temperature additives such as XCC (viscosifier), AADC (filter loss reducer) and FSCC (plugging agent). The detailed composition of the drilling fluid is:2%XCC+1% AA DC+3%SPNH+1%SMP+3%FSCC+0.5%Na₂SO₃. SEM experiment showed that shale cores taken from a well drilled with this drilling fluid had layered micro-fractures apparently plugged, and a dense tree-like polymer layer parallel to the direction of the micro-fractures was found on the surface of the shale cores. FT-IR experimental results showed that, after aging at 220℃, the drilling fluid still had stable mud properties, good rheology and filtration properties. The inhibitive capacity and lubricity of the drilling fluid can satisfy the needs of drilling operation. This drilling fluid was able to tolerate the contamination from 10% clay and 5% drilled cuttings, or from 10%KCl+20%NaCl salt solution. The LC50 of the drilling fluid measured was 80,000 mg/L, conforming to the stipulated discharge criteria. The drilling fluid has been successfully used to drill the Well 24 located in the Sebei-1 gas field.
