The welded pipe products is partitioned into five arrangements as per its characteristics and its six developing directions toward thin wall thickness,thick wall thickness,high accuracy,high grade,inside burr removal and anti-corrosion,etc.are analyzed.

我国中小直径焊管经过20世纪80~90年代的飞速发展，品种结构和应用领域已经有较大的改善，但是低压流体输送管、一般结构管比例较大，与焊管发达国家在锅炉、化工、油井、机械构件、高压流体输送用承压钢管和精密钢管领域不断扩大焊管的使用范围、提高高等级焊管使用数量方面存在一定的差距。

Requests on resistance of corrosion destructibility of sealing interfaces that related to sealing up and cementing exercises in petroleum engineering are more and more of rigidity. It is urgently needs to resolve all sorts of problems that affect interface bonding quality. Conventional cement slurry design resist the destructive function worse, and can't like to satisfy the request to carry on latter production such as perforation, acidify, fracture etc.

常规油井水泥抵抗破坏的性能较差，不能很好满足水泥环抗冲击振动以及射孔、压裂等各种变形破坏的要求，这在一定程度上限制了小间隙、大位移、定向与水平井等特殊钻井工艺技术的发展，也制约了后期压裂、酸化等诸多开发工艺措施的实施。

The Red Adair Company capped more than one hundred wells.

瑞德。埃德尔公司盖住了100多个油井。

This equipment use and popularity has the extremely vital significance to protect oil aerosphere, reduce the recovery cost, enhance the recovery ratio, protect environment.

作业完毕后，尚需把高比重的压井液替换出来，最为严重的是高比重压井液对地层造成污染和堵塞，导致区块内油井产量降低和注水井的过早损坏。

Oil/water two-phase flow is very common in oil production wells of affusion oil field and the measurement of oil/water two-phase flow is the key of the oil/water two-phase profiling technique.

摘要注水开发油田的油井中普遍存在油水两相流动，油水两相流测量问题是油水两相产出剖面技术的关键。

Double Anchor Rod Pumps This pump is designed to be used in large anchor force oil well.

双卡杆式抽油泵适用于要求锚定力大的油井。

The experimental results show that it is necessary to treat the formation with the temporary plugging agent to seal the pay zones for selectively injecting gel into aqueous layers when the effluent water pressure is higher than that of pay zones, or the fractures in oil-bearing zones are much wider than those in the aqueous layer.

在油井水层出水压力高于油层压力或者产油层裂缝大于出水层裂缝情况下，采用笼统注入方式堵水须进行暂堵处理，以封住产油层，使堵剂主剂选择性进入水层。

Can be applied in oil wells of both high and low temperature.

在高温油井和低温油井均可使用。

In an oil well, the casing is a steel circular pipe, and it would confine and guide the electromagnetic wave propagating; and the electric properties of the fluid media would determine the propagation factor of the guided wave and affect the distribution state of the electromagnetic field.

油井内的套管是钢铁质圆管，对电磁波的传播将产生限制和引导作用；油井内流体介质的电性质将决定导波的传播常数，影响电磁场在井的轴向上和横向上的分布状态和波的传播特性。

An oil well at the centre of a massive spill in the Timor Sea off the north-west coast of Australia is on fire.

澳大利亚西北海岸帝汶海大油井中心的一座油井发生火灾。

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。
