This text passes correctly elm two of Daqing oil field is united --One Song unite person who bury oil pipeline scene to live in environment survey and study, is it take a sample test , environmental corrosivity survey , corrosivity measuring of pipeline and assess of soil to excavate, is it cause person who bury pipeline antiseptic layers of invalid main factor to find out , confirm the environmental grade of corrosion of soil according to environmental comprehensive physics and chemistry index of soil, grasp pipeline antiseptic invalid law of layer , study antiseptic layers of resistivity decay law and to influence that negative pole protect, is it suitable for person who bury antiseptic layer of life-span of the pipeline calculate formulae and actual effect criterion model to propose on the basis of this text, illustrate and simply analyse oil field long to fail person who bury antiseptic layer of surplus ability to work of the pipeline, unite for elm two --One Song unite pipeline antiseptic maintenance of layer , is it put forward science rational suggestion to change.

本文通过对大庆油田榆二联——宋一联埋地输油管道所处环境的现场调研、开挖取样化验、环境土壤的腐蚀性勘测、管线的腐蚀性检测和评估，找出引起埋地管道防腐层失效的主要因素，并根据环境土壤的综合理化指标确定该段环境土壤的腐蚀等级，掌握管道防腐层的失效规律，研究防腐层电阻率衰减规律及其对阴极保护的影响，在本文的基础上提出适用于埋地管道防腐层寿命计算公式和失效判据模型，例证和浅析油田长输埋地管道防腐层剩余工作能力，为榆二联——宋一联管道防腐层的维修、更换提出科学合理的建议。

We have found that The content of water and iron is the main cause of the phenomenon of collapse of the electric field of the electric dehydrator. The natural surfacants, polymers and colloidal FeS particles are the key cause of the form of the oil-water intermediate layer of the 4th Produced Factory.

天然表活剂、聚合物以及硫化亚铁胶体或微粒的作用是大庆油田采油四厂原油脱水时形成了较稳定的油包水型中间层的主要原因。

First, select four kinds of main risks source from bigly celebrate the main risk in region source, namely the flood, drought, sand-dust weather and petroleum pollution accident, etc. According to the different a request for to habitat, study this 19 kinds of landscapes ecosystem type of the Regional induce for 7 kinds of ecosystems system: Then the marsh of bulrush, lakes and reservoirs , salt alkali wasteland, prairie, island form wood, farmland, town. The difference is proceeded by characteristic according to each type ecosystem to the analysis of four kinds of main risks source, including the certain risk all rate, delimiting the space distribute, analyzing the risk strength to the receptor etc. At proceed the revelation the different from endanger to analyze the inside, this text borrows ecosystem index number that this index sign to reflect primarily habitat the ecosystem meaning of the type of habitat the different from position, with weak an index number to show the destructibility of the habitat, from but compute each ecosystem that is lost by ecosystem system an index number.

首先，从大庆地区主要的风险源中遴选出四种主要的风险源，即洪涝、干旱、沙尘天气和石油污染等；依据不同生物类群对生境的要求，将本研究区域的19种景观生态类型归纳为7种生态系统：即芦苇沼泽、湖泡库渠、盐碱荒地、草甸草原、岛状林、农田、城镇；对四种主要风险源的进行分析，包括确定风险概率，划定空间分布，对风险受体的作用强度分析等；在进行暴露和危害分析中，本文主要借生态指数这一指标来反映不同生境类型的生态意义和地位，以脆弱度指数来体现不同生境的易损性，从而计算出各受体生态系统的生态损失度指数；由于各主要风险物质对风险受体的作用强度是不同的，对形成区域性生态风险的作用大小也有差异，因此本文采用层次分析法对主要生态风险物质进行综合评价，并把判断矩阵排序权值的合理计算问题归为—非线性化问题，并提出用基于遗传算法(GA[5])的层次分析模型进行权重分析；进行风险表征，即综合前面两个阶段的信息，对环境中风险的性质和强度以及风险评价过程中不确定性问题进行分析与描述，并划分出五级生态风险区；最后，根据划分的五级生态风险区的特征，分别提出针对各生态风险区的生态风险管理对策。

A method of state equation for determining minimum miscible pressure of CO_2;2. The minimum miscible pressure s of CO2,N2,natural gas and crude oil are measured.

通过气驱细管实验，在地层条件下测定了大庆油田芳48断块在二氧化碳、氮和天然气驱下原油采收率与压力的关系，由此确定了原油与二氧化碳、氮和天然气的最小混相压力。

There's new speculation that UK Prince William could marry long-time girlfriend Kate Middleton in 2012 - the same year as the summer Olympics in London and the Queen's Diamond Jubilee.

近日有传闻称，威廉王子可能将于2012年迎娶相恋多年的女友凯特·米德尔顿，由于2012年正值伦敦举办夏季奥运会，同时也是女王伊丽莎白二世登基60周年的"钻石大庆"，可谓"三喜临门"。
