铝合金抽油杆柱的深抽可行性

Feasibility for Aluminumalloy Sucker Rod Stringto Use in Deep Well Pumping

铝合金抽油杆具有重量轻、弹性好、抗弯抗压抗扭能力中等、耐腐蚀和价格适中等特点。根据线性振动理论，讨论了铝合金抽油杆柱的动态特性，得到了杆柱的固有频率和频率因子，并利用ＡＰＩ推荐方法给出了铝合金杆柱的设计实例。结果表明，铝合金抽油杆柱可以用于目前的深抽井。

An aluminumalloy suckerrod string has a series of features such as light in weight,good in elasticity,intermidiate in bending strength,compression strength and torsional strength,resistant to corrosion and reasonable in price.According to the theory of linear vibration,its dynamic characteristics is discussed,its intrinsic freuency and frequency factor are obtained,and an example of designing aluminumalloy sucker rod string by API recommended method also is given.Results may be used in present deep well pumping.
