  oilfield soil
    (4) After culture and domestication by using liquid paraffin as the single carbon source, the Sinkiang oilfield soil dipped in the oil for a long time would produce some surfactants to emulsify liquid paraffin. These surfactants could change thequality of oil-water interface of the crude oil emulsion and greatly reduce the interface intension and demulsify the emulsion. Bacterium TR-1 was separated from the mixed bacteria and had great de-emulsifying ability.
    (4)长期受石油浸泡的油田土壤经过以液体石蜡为单一碳源的培养和驯化后,在液体石蜡的诱导下会产生一些表面活性物质乳化石蜡,这些表面活性物质可以改变原油乳状液中油水界面的性质,大大降低界面张力,使原油乳状液破乳脱水。

Since it is hard for the available gauge of AC 4 Pole Method to measure the soil of high resistivity, two methods of expanding the measuring range are set forth in the paper, namely, Pole-Distance (PD) regulating and Parallel Resistance (PR) regulating. PD regulating is a method of adopting different pole destances in order to change the measuring range of resistivity instrument. PR is to parallel a known value resistor between current and pole or between potential and pole so as to help ZC-8 instrument to enlarge...

Since it is hard for the available gauge of AC 4 Pole Method to measure the soil of high resistivity, two methods of expanding the measuring range are set forth in the paper, namely, Pole-Distance (PD) regulating and Parallel Resistance (PR) regulating. PD regulating is a method of adopting different pole destances in order to change the measuring range of resistivity instrument. PR is to parallel a known value resistor between current and pole or between potential and pole so as to help ZC-8 instrument to enlarge its measuring range of high resistivity. Formulas for both methods have been worked out with the discussion of PR's r value definition and the influence on measuring the calculated value as well as the principle of selecting f0and its practical application. The improved AC 4 Pole Method can help solve the problem that the conventional one couldn't , which was improved during the investigation of soil corrosion in Tarim Oil Field, Xinjiang.

由于现有的交流四极法仪表难以在高电阻率土壤中进行测量,为此,提出了两种扩大四极法测量电阻率范围的方法,即极距调整法和并联电阻法。极距调整法是采用不等的电极间距,以改变电阻表的测量范围。并联电阻法是在电流电极之间或电位电极之间并联一个已知阻值的电阻,以提高ZC-8表测量高电阻率的范围。分别推导了它们的计算公式,讨论了并联电阻法r值的确定、对测量计算值的影响和R_0的选用原则及其实际应用。改进后的交流四极法在新疆塔里木油田土壤腐蚀调查中,解决了对土壤高电阻率测量用常规的四极法根本无法测定的难题。

Soil corrosion conditions of 20# steel in Baolang oilfield was studied through field buried sample tests in Baobei, Baozhong, Baonan, Benbutu and Zhongmachang blocks and by using microanalysis and electrochemical testing methods. Soil corrosion in Zhongmachang block is strong, while in other blocks are medium. Soil corrosion type of 20# steel in Baolang oilfield is oxygen depolarization corrosion controlled by cathodic reaction.SRB corrosion also exists in this oilfield.

通过20#钢在宝浪油田宝北、宝中、宝南、本布图、种马场等五个区块土壤中的现场理片试验,同时结合微观分析及电化学测试方法,对20#钢在宝浪油田土壤中的腐蚀状况进行了研究.结果表明,宝浪油田种马场区块土壤腐蚀属强腐蚀,其它区块属中等腐蚀.经过进一步的分析讨论,指出20#钢在宝浪油田土壤壤中的腐蚀属阴极控制的氧去极化腐蚀,同时存在SRB细菌腐蚀.
