Based on the conodont data, the evolutionary sequence of the Ordovician conodonts in the platform facies of the Tarim Basin was cleaned, one assemblage and 7 biozones are revised. After the cleaning, there are 1 assemblage and 20 biozones across the Ordovician in ascending order in the platform facies region of the Tarim Basin.

基于所获得的牙形石系统资料，对塔里木盆地奥陶纪台地相区已建牙形石生物地层序列进行了清理，确定了1个牙形石组合和20个牙形石带，据新的资料对8个原有的生物地层单元作了厘定。

Use of analytical solution for predicting the ground settlement induced by tunneling in free soil and Plasticity Yield Criterion get the calculation process of analytical solution for predicting the plastic zone induced by tunneling in free soil.

利用预测自由地层中隧道开挖引起土体沉降的解析解，引入理想塑性屈服准则，得到了自由地层中隧道开挖产生塑性区范围的解析解的计算过程。

The inhibiter is much sensibility on formation water, solid y inanimate matter, power of hydrogen of oil, so power of hydrogen of oil and other element should be controled when the inhibiter is used.

该抑制剂对地层水、固体无机杂质、原油的酸碱性比较敏感，使用时应注意控制原油体系的酸碱度和地层水、固体无机杂质等抑制剂的影响。

This paper analyzes that the main reason of low injectivity of water injection wells is that the Sr 2+ in formation water reacts with the SO 4 2- in the Yellow River water to produce precipitate of BaSO 4 when the Yellow River water mixes with formation water.

该文分析了胜坨油田注水井吸水能力降低的主要原因是黄河水与地层污水混注时，地层水中的Sr2＋、Ba2＋与黄河水中的SO2－4反应生成BaSO4、SrSO4沉淀。

There developed many red detrital laterite strata named as red-bed in the Cenozoic stratum of the eastern China oilfields.
