Theequivalence percolation resistance law is accurate enough to be used in productivitycalculation of horizontal well pattern.(3) Productivity of mixed well pattern of horizontalwell or multilateral horizontal well and vertical well is constructed and formulae are simpleenough to be used in the oilfield. The patterns include 5-spot pattern,7-spot pattern and9-spot pattern.(4) Productivity formula of united rectangular well pattern of horizontaland vertical wells is constructed. By this formula, the calculation results show that fora horizontal well length, there is a shape factor at which the productivity of the patternis biggest. So optimum method of the well pattern is proposed.(5) A new concept ofdimensionless length of horizontal well is advanced and the relationship of optimum shapefactor of the rectangular well pattern against dimensionless length of horizontal well ispresented. The influences of length of the horizontal well, area of the well pattern unitand the thickness of reservior are concerned.
利用该公式计算表明:当水平井长度一定时,存在一个最优井网形状,使得水平井的产能最大,在此基础上提出了水平井井网的优化方法;(5)提出了水平井无因次长度的概念,给出了联合井网最优井网形状因子与水平井无因次长度的关系式,并对水平井长度、油层厚度及井网面积对产能的影响进行了分析;(6)推导出了一无限水平井井排在XY 平面内势的解析解,为不同水平井整体开发井网或水平井和直井井网整体开发渗流理论的研究奠定了理论基础;(7)建立了交错式水平井与直井整体开发渗流理论,给出了拟三维条件下井网产能的精确解析解及该井网最优井网形状因子与水平井无因次长度的关系,并对产能的影响因素进行了分析;(8)建立了水平井与水平井正排列井网、交错排列井网条件下渗流理论及井网产能在拟三维条件下的精确解析解,给出了交错井网条件下最优井网形状因子与水平井无因次长度的关系,通过与正方形井网对比,说明优化井网可大幅度提高开采效果;(9)建立了分支水平井和直井面积井网水油两相非活塞驱替条件下渗流问题的解析解,给出了见水前后无因次产量与无因次时间的关系式以及见水时间等。

Some conclusions from the study on human driving factor are:(1) the human activity is much more active factor to the process of desertification which mainly incarnates on the changes of the landuse fashion (from traditional rangeland 100 years ago come to interlacing agro-pastoral region) and enhance of landuse intensity (over-cultivation, over-grassing and over-fuel collection);(2) the natural vegetation had been destroyed suicidally by human activities that had accelerated to the development desertification.
在人为驱动力的分析中,得到以下一些初步的结论:(1)人类活动是本地区沙漠化过程中更加活跃的驱动因子,体现在土地利用方式的转变(从传统的牧业草原到今日的农牧交错区)和强度的增加(过度开垦、放牧、樵采等);(2)由此对自然植被群落毁灭性的破坏,加速沙漠化的进程。

Customer segmentation is a critical step to the success of target or segment marketing. The effectiveness of customer segmentation depends on a good number of variables such as customers' demographic, behavioral, geographic, and psychographic characteristics. However, the huge combinations and correlations among variables make customer segmentation a challenging task, even with the aids of information technologies. The industry is desperate for effectual and powerful tool for excavating customer knowledge from the large accumulated data in the corporate database management system.
摘要顾客分群对於目标行销或市场切割的成功与否都是一个重要的关键步骤,顾客分群结果的优劣取决於其所采用的分群因子,顾客分群中常使用的分群因子有顾客的人口统计资讯、行为特徵、地理性资讯与心理方面的特徵等,然而,这大量与因子复合交错的资讯使得顾客分群成为企业的一个挑战,并且渴望寻求一个能够从大量累积的资料库系统中挖掘知识的工具。
