抽油杆

So the theory to the application of rod string absorber in engineering is provided.

本文的定量研究为抽油杆减震器在工程中的应用提供了理论支持。

Fess up — it's not the good old USA as represented by the sucker taxpayers conned by your patriotic blather.

愈-这不是很好的旧美国为代表的抽油杆纳税人c onned由您的爱国废话。

Hot washing by moving hot washing truck and hollow sucker rod is efficient, less in washing fluid , no formation contaminant, no casinghead gas release. It adapts oil wells with low reservoir pressure and deep depth of plunger and serious paraffin problem.

活动热洗车配合空心抽油杆热洗清蜡热效率高、洗井液少、不伤害油层、不用放套气，适合于地层压力低、下泵深度较深、结蜡严重、常规洗井困难的油井。

In the light of the problems with il1e existing and centralizels, a new nylon centralizer is developed.

针对现有扶正器存在的问题，研制了具有扶正和刮蜡功能的新型抽油杆尼龙扶正器。

It needed install to centralizer on sucker rod string.

需要在抽油杆柱上安装扶正器。

Therefore, researching on the influence of effluent for vibration property of the sucker rod string has important reference value for rational configuration interval design of sucker rod centralizer, and also has important significant theoretical actual meaning on the simulation of the dynamic parameters and optimizing the running of polymer holes.

因此，研究聚驱抽油机井产出液对抽油杆柱振动特性的影响，对于指导扶正器配置间距设计、完善聚驱抽油机井动态参数仿真与运行优化技术都具有重要的理论和实际意义。

An inside conical surface at the lower end of the joint is designed to ensure the shaft swing freely within an angle range of 10°, thereby the axial bending stress caused by the deflection of the borehole can be eliminated effectively.

这种装置采用类似球形关节的旋转机构，消除了抽油杆柱上下往复运动产生的倒扣扭矩；在短节下端设计有10°的内圆锥表面，使转轴能够在10°范围内自由转动，从而有效地消除了由于井身弯曲而产生的轴向弯曲应力。

Shengli Oilfield Freet Petroleum Equipment Co., Ltd. was successfully reformed from Sinopec on May, 2005 and it is a joint-venture company with four industrial zones, 0.32 billion yuan register capital, 1764 employees and 3.6 billion yuan production ability. Its ' main products are tubing and casing threading, VIT tubing, pumping unit, sucker rod, ERW casing/ line pipe, PE pipe and so on. All products of Freet has the right to use API logo.

胜利油田孚瑞特石油装备有限公司是2005年5月从胜利油田改制的中外合资企业，注册资本3.2亿元，职工1764人，拥有四个工业园区，产能规模达到36亿元，主要生产油套管螺纹加工、隔热油管、抽油机、抽油杆、 ERW 套管和塑料复合管等产品，公司所有产品均获美国石油协会 API 会标使用许可证。

It points out the necessity of tubing anchor in pumping well s,especially in deep wells.

定量分析了抽油机井油管自由悬挂可能造成的危害：降低泵效；油管柱振动加速了油管的疲劳破坏；油管屈曲造成套管、油管、抽油杆柱之间的多重磨损。

At present, the location of the anti-lopsided wear centralizer used in fields is mainly based on the deviation angle. In fact, lopsided wear may be caused by the change of azimuth angle or by the vertical well section and hold angle section during the working of the bucket rod.

目前油田矿场主要根据井斜角来确定防偏磨扶正器下入位置，实际上方位角变化也能导致偏磨，抽油杆杆柱在运动过程中直井段和稳斜段也会产生偏磨。

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。
