安装助抽增液器前后抽油井载荷分析

The load of pump well before and after installing pumping assistor

依据油井载荷理论计算公式,对助抽增液器安装前后抽油杆的受力分布进行了计算分析,找出提高油井泵效、减小抽油杆偏磨、降低杆底部断脱和油管底部漏失的新途径。

The distribution of force on sucker rod before and after installing pumping assistor is computed based on the formula of oil well loading theory. This is a new way to improve pump efficiency, to reduce eccentric wear, bottom rod breaking, and leaking from bottom tubing.
