Line meter ( m ) and grout take ( t ) method were taken successively for measurement of grouting quantity in china 我国灌浆工程的工程量主要采用灌浆孔进尺（延长米， m ）和灌浆注入量( t )两种方法计量。

Two relation models between the drill footage and proved reserves are introduced : gompertz model and exponential model 摘要为估算油气探明储量，介绍了探井进尺和探明储量间的2种统计模型：龚帕兹模型和指数模型。

Since the pebble structure is of big pellet easy to be permeated ant it is difficult to smash and drill , the appliance with big diameter and deep cast - in - place pile has been greatly restricted 卵石地基具有颗粒大、透水性强、进尺和破碎困难、容易垮孔等困难，限制了大直径深孔钻孔灌注桩在其中的应用。

Therefore , a positive research method was adopted to put forward two hypotheses during the oil and gas drilling works , i . e , a certain relation existed between operation ' s cost and drilling footage and cycle respectively 为此，采用实证研究方法，针对油气钻井作业的过程提出两个假设：钻井作业成本与钻井进尺呈一定的比例关系；钻井作业成本与钻井周期呈一定的比例关系。

Moreover , we also gave some theoretical studies on the resistant pipe - pushing construction technique for middle and long distance high pipes in sand soil layers , from which not only the difficulties in the rain pipe construction problem in jianyu road of yulin city have been overcome successfully , but also the new and valuable techniques and experiences for the pipe - pushing construction in sand soil layers have been obtained 试验研究表明上述技术措施的有效性，同时还对砂土层中长距离顶管法施工技术进行了一定的理论探讨，从而使榆林市建榆路雨水管道顶管法施工开始完全不能进尺的僵局予以打破而且为砂土地层中顶管法施工提供了新的技术和经验

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。

Since the shallow depth excavation is the main factor to cause ground settlement in shenzhen subway tunnel , this paper discusses some corresponding countermeasures including the improvement of ground property , appropriate draining of groundwater , scheduled excavation depth and width , etc , to control strata distortion and surface settlement , and argues that these measures are expected to effectively control surface settlement while constructing city subway in soft ground excavation 摘要针对深圳地铁浅埋暗挖隧道施工中影响地表下降及地层变形的因素，提出了遵循“十八字”原则、改善土体特性、适度排放地下水、根据地层条件选择施工方法、增大左右线隧道开挖面的距离、合理确定开挖进尺、提高施工效率、加强初期支护、及时施作二次衬砌等对策。
