Abstract : the drilling resistance of the erkaijing well in oil field of north shanxi is caused by hydration expansion of mud stone and mud cake deposition of porous sandstone 文摘:陕北油石二开井段遇阻的原因为泥岩的水化膨胀和孔隙性砂岩的泥饼沉积。
The countermeasures to it are physical treatment ( short - range running and increasing output volume of debris ) and chemical treatment ( adding inhibitor of fa367 and gps ) 对策主要有物理方法(如短程起下钻、加大排量等) 、化学方法(加入强抑制剂fa367 、加入gps ，提高泥饼质量)等。
The cellulose fibre can be blended with sewage sludge or sewage cake for conversion via aerobic or anaerobic digestion of the blended material to produce quality compost and a liquid nutrient that can be used as a fertiliser 纤维素纤维可以与污水污泥或污水泥饼混合，然后透过混合材料的好氧消化或厌氧消化来生成可以用作化肥的高质量混合肥料和营养液。
This patented process uses steam to thermally treat unsorted municipal , light industrial , commercial and agricultural wastes that can also include sewage cake , sludge and screenings to produce a cellulose - based fibre from which recyclable ferrous and non - ferrous metals , plastics , glass and batteries can be mechanically extracted 此项专利使用蒸汽来对未分类的城市、轻工业、商业与农业垃圾进行热处理(这些垃圾中也包括污水泥饼、淤渣与碎屑)以从可以透过机械提取的，可回收的含铁与不含铁物质、塑料、玻璃与电池生成纤维素纤维。
Abstract : we use ordinary industrial boiler to crement the mixed fuel that made of digested sludge s cake and coal . this paper offers datas of compostion about the mixed fuel and situation of actual experiments in motion , obtions the best mixed - proportion of sludge and coal , estimates environmental benefits and economic results produced by this methods 文摘:利用普通工业锅炉将消化污泥泥饼与煤制成混合燃料进行焚烧处理，提供了混合燃料组份分析及实际运行试验情况，得出了切实合理可行的泥煤最佳配比，并就产生的社会经济效益和环境效益进行了评估。
After this experiment , i need not say that i wanted no sort of earthen ware for my use ; but i must needs say , as to the shapes of them , they were very indifferent , as any one may suppose , when i had no way of making them ; but as the children make dirt - pies , or as a woman would make pies , that never learn d to raise past 这次实验成功后，不用说，我不缺什么陶器用了。但我必须说，这些东西的形状，是很不像样的。大家也可以想象，因为我没有办法制造这些东西，只能像小孩子做泥饼，或像不会和面粉的女人做馅饼那样去做。
The lab study and field application indicate that this system has the feature of powerful repress , highly blind in , better rheology , better quality of mud cake and low filtration , resolved the complication of fall down and shrinking drilling in salt of gypsum layers , decreased the drilling circle , cut down the drilling cost and raised the colligation economic effect 室内研究和现场应用表明，该体系具有强抑制、强封堵、流变性好、泥饼质量好、滤失量小的特点，解决了膏盐层、盐岩层的缩径、垮塌，缩短了钻井周期，降低了钻井成本，提高了综合经济效益。
