在石油钻采工地，钻柱事故时有发生，一般均为恶性事故，一旦发生，便会造成很大的经济损失，严重时导致油井报废。

The mapping rules between heterogeneous databases were analysed and the mapping to PCEDM database from daily data table of oil wells was established according to the features of exploration-development database and the PCEDM database, furthermore the data in this table were transferred into PCEDM database based on SSIS.

最后，分析了异构数据库间的映射规则，根据勘探开发数据库和PCEDM数据库的的结构特点，建立了油井日数据表向PCEDM数据库中的映射，并基于SSIS将表中数据迁移到PCEDM数据库中。

Bess, a sweet-faced and trusting girl, is ''not quite right in the head,'' and her close-knit community is not pleased by her decision to marry Jan, who works on one of the big oil rigs in the North Sea.

贝丝是个甜美虔诚的女孩，但别人说她&脑袋不那么灵光&，而且的邻里对她嫁给简--一个北海油井工人--的决定并不表示欢迎。

Through analysis to the pumping unit's load characteristic, the relationship between the position of the suspension point load's peak value and the oil well's parameters has been obtained and a new method about the transforming of the pumping unit with downward beam balance weight is proposed.

分析常规游梁式抽油机的载荷特性，得出悬点载荷的峰值出现的位置与井况参数的关系，提出一种下偏杠铃抽油机改造方法，依据油井抽汲参数调节下偏杠铃的角度，使其最大力臂与悬点最大载荷对应，提高抽油机的平衡效果。

The primary result indicated that the work condition monitoring system of sucker rod pumping well was in good working order in site.

初步结果表明，油田油井远程监测系统的实际运行取得了良好的效果。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
