Abstract : the rheology of oilwell cement slurry is the key factor to the slurry for formulation designing and safe cementing 文摘:油井水泥浆的流变性是水泥浆配方设计的核心及安全施工的前提。
Available in moderate sulfate - resistant ( msr ) and high sulfate - resistant ( hsr ) grades . this product is intended for use as a basic well cement 有中抗硫酸盐型（ msr ）和高抗硫盐盐（ hsr ）两类，是一种基本油井水泥。
Stable characteristic , with uniform paricle size distribution , can be used as heat stabilizer to impove well cement strength loss under high temperature and pressure 性能稳定,粒径分布均匀,可作为热稳定剂,改善油井水泥高温高压下的强度损失。
In order to respond to the police of enviromental , i have analyzed the advantages and disadvantage s of in bulk and in bag , and i assumed that found the blend concrete station in the east region of sichuan which near the main battalfiled of artesian well in this artical , i have analyzed direction of the fund floating of oilwell concrete supply chain and found out the advantages and disadvantages exist at present in this 总之,油井水泥是一种特殊的钻井物资,四川石油管理局油井水泥供应链是一个有特点的供应链。保证油井水泥的定时定点到达,降低水泥采购成本和供应链交易成本,这是实行油井水泥供应链管理的目的所在。为了达到这一目的,本文从供应链基本观点出发、从第一手数据出发、从目前供应链各环节现状出发,
The perfessional reorganization and reformation have urged the estabilishment of supply chain , such as oilwell cement and something else , the material general company and supplier of oilwell cement are the main acesses of supply chain , the material general company is the main organizer for oilwell cement supply chain who responsible for the organization and coordination of supply chain , the corporation whose operation is took under well , the material general company , the concrete supplier , raw assistant material supplier and every kind of transporter are the cells of supply chain , to estabilish the strategical patnership with the next node is the important foundationtone of oilwell cement supply chain 专业化重组改革,催生了油井水泥等物资供应链的建立,在油井水泥供应链中,物资总公司与油井水泥供应商是供应链的主要接口,物资总公司承担了供应链管理的组织、协调职责,是油井水泥供应链的主要组织者,井下作业公司、物资总公司、水泥供应商、原辅材料供应商及各类运输商是供应链的组成细胞,与下一个节点建立战略合作伙伴关系是油井水泥供应链管理的重要基石。
I have taken impotance to analyze the rallying point of famous product , concrete cost and capability of providing and guarantee in this artical , meanwhile , i have caculated the quantity of concrete needed for the year and got the regression equation with the historic data for drilling footage of eight years and the consuming quantity of oilwell cement by the method of linear regression , and it has very significance for the making of stock contract and the plan of concrete production , i have analyzed the physical distribution of oilwell cement by the transpotation flex and the advantage or disadvantage between direct distribution and distribution to store in this artical , and i have tried to find the balance point of the two distribution ways by the ecnomic analysis and pointd out the conception of economic semidiameter , and come to the conclusion of direct distribution , distribution to store , and subarea of distribution to store at last 本文对油井水泥供应商在品牌号召力、水泥成本、供应保障能力等方面进行了详尽分析,并对供应商进行了能力排序;用线性回归方法从八年钻井进尺与油井水泥消耗量的历史数据推算了当年度油井水泥需求量,得出了回归方程,这对于油井水泥采购合同的制订、水泥供应商生产计划的制订具有相当重要的意义;从运输弹性分析出发对油井水泥物流配送进行了研究,对直达配送、入库配送的优缺点进行了详细的分析,在经济分析的基础上力求找到两种配送方式的均衡点,并提出了经济半径的概念,得出了直达配送、入库配送、入库分区距离等几项结论。
