By combing the characteristics of drilling in Antarctic region, performance requirements on drilling fluid for Antarctic low temperature conditions, and research progress of low temperature drilling fluid, current problems of the drilling fluid have been sorted out, and the development direction of the drilling fluid has been pointed out. Drilling in the Antarctic region mainly includes drilling in snow, ice and subglacial rock formations, and drilling in Antarctic low temperature conditions will face problems in four aspects:(1) low temperature and large temperature changes in the drilling area;(2) likely well leakage and drillstring-sticking in the snow layer, creep in the ice layer, ice chip gathering jamming in the warm ice layer, well wall collapse in the subglacial rock formations;(3) lack of infrastructure and difficulty in logistical support;(4) fragile environment and low carrying capacity. After years of development, progresses have been made on low-temperature drilling fluids for the Antarctic region. Low-temperature petroleum-based drilling fluid, ethanol/ethylene glycol-based drilling fluid, ester-based drilling fluid and silicone oil-based drilling fluid have been developed. However, these drilling fluids have problems such as insufficient low-temperature tolerance, low environmental performance and weak wellbore stability, etc. In order to meet the performance requirements of drilling fluid under low-temperature conditions in Antarctic region, the working mechanisms of low-temperature drilling fluid must be examined in depth;environment-friendly low-temperature base fluid of drilling fluid and related additives must be developed to prepare environmentally friendly low temperature drilling fluid systems;multi-functional integrated adjustment method for drilling fluid must be worked out to ensure well wall stability and improve cutting-carry capacity when drilling ice formations and ice-rock interlayers;and on-site support operation codes must be establ

为探讨夏季缓解奶牛热应激喷淋水滴粒径对降温效果的影响,通过现场实验测试了3种平均喷淋水滴粒径(0.829、0.947、1.127 mm)缓解奶牛热应激效果。实验中利用热像仪采集奶牛体表温度,同时测定呼吸频率、直肠温度生理指标,并在此基础上利用Merkel焓差理论分析计算奶牛喷淋降温换热量。结果表明,喷淋过程中,3种粒径(0.829、0.947、1.127 mm)在奶牛脖颈区域平均降温为0.7、1.1、0.9℃,腹部区域平均降温为0.7、1.4、1.5℃,平均呼吸频率分别降低0.6、4.2、2.1次/min;喷淋结束后,3种粒径在奶牛脖颈区域平均降温为0.2、0.4、0.6℃,腹部区域平均降温为0.1、0.5、0.6℃,平均呼吸频率降低-0.4、1.4、1.2次/min。喷淋前后奶牛直肠温度均控制在稳定范围内,且平均喷淋水滴粒径0.947 mm和1.127 mm低于0.829 mm时的奶牛平均直肠温度。3种平均喷淋水滴粒径对应的奶牛单位时间换热量分别为417.4、469.9、430.4 W,其中0.947 mm平均喷淋水滴粒径下换热量最大。因此,平均喷淋水滴粒径0.947 mm更适用于夏季奶牛喷淋降温。

针对农用烟囱风机流量小,能效比偏低的问题,采用数值模拟的方法,在节约投资成本的前提下,不改变烟囱风机的叶片造型,对其配套的风筒结构尺寸进行改型优化。利用试验测试原型风机的性能后,通过数值模拟方法,从烟囱风机的风筒内径d(用改型后风筒内径与原型风筒内径之比,即内径比k表示)、出口段扩散角度α和扩散深度l这3个方面进行单因素改型优化。在单因素优化基础上,采用正交优化方法综合以上3个因素,得到风筒正交优化设计参数。根据正交所得优化参数制备相应风筒样机,进行试验性能测试。结果表明:1)单因素优化模拟下,与原型风机相比,k=0.985时风量和能效比提高了4.7%和4.0%;α=28°时风量和能效比提高了4.7%和5.3%;l=250 mm时风量和能效比提高了1.8%和3.2%。2)多因素正交数值模拟下,与原型风机相比,k=0.988、α=28°、l=200 mm时风量和能效比提高了7.9%和8.1%;3)对优化风机进行测试,与原型风机相比,优化风机风量和能效比提高4.6%和4.5%。

通过系统梳理南极地区钻井的特点、南极低温条件对钻井液的性能要求、低温钻井液的研究进展,找出了目前存在的问题,指出了南极低温钻井液的发展方向。南极地区钻井主要包括雪层、冰层和冰下岩层钻井,南极低温条件下钻井面临4个方面的问题:①钻井区低温、温度变化跨度大;②雪层易井漏卡钻、冰层易蠕变、暖冰层易冰屑聚集卡钻、冰下岩层易井壁坍塌;③基础设施缺乏,后勤保障难度大;④环境脆弱,承载能力低。南极低温钻井液经过多年发展取得了一定的进展,研发了低温石油基钻井液、醇类钻井液、酯类钻井液和硅油类钻井液,但普遍存在耐低温不足、环保性能低以及井壁稳定性差等问题。为满足南极低温条件下钻井液的性能要求,未来必须深入研究低温钻井液作用机理,研发环境友好型低温钻井液基液及相关添加剂,构建环境友好型低温钻井液体系,建立可保持井壁稳定、提高钻遇冰层和冰岩夹层时的携屑能力的多功能一体化调控方法,进而形成现场配套施工规范,为南极钻井提供技术支撑。

针对深井超深井钻井过程中高扭矩和高摩阻等难题,利用硼酸、多元醇和长链脂肪酸等原料,合成出一种耐高温高盐钻井液润滑剂SOB,该润滑剂在高温高盐条件下具有良好的润滑性能。在5%基浆中加入1%润滑剂SOB后,润滑系数降低率为92.7%,泥饼的黏附系数降低至0.0405,极压润滑持效性强;210℃下润滑系数降低率保持在90.2%,210℃、35%NaCl条件下润滑系数降低率保持在81.3%。高温高盐条件下SOB在高密度钻井液中配伍性良好,200℃老化后对钻井液的流变性无影响,能够降低钻井液滤失量,润滑系数降低率为45.09%,相比常规润滑剂性能优越,这是由于润滑剂能够在钻具表面有效吸附,形成一层疏水性较强的膜,使钻具与井壁的直接接触变成了润滑膜之间的接触,从而降低摩擦。
