新型液压抽油机研制

Development of new hydraulic drive pumping unit

针对目前有杆抽油机难于适应特殊环境（如海上平台）的特殊要求的现状,研制了一种新型液压抽油机。该抽油机具有体积小、占地面积少,易于实现长冲程、低冲次、便于实现自动化控制等优点。本文结合环渤海地区滩海油田油气开采特殊性,对液压抽油机在该地区应用的可行性进行了具体分析和论述。

It is difficult for sucker rod pump to adapt to special environment (i.e. , offshore platform) at present time, so that a new hydraulic drive pumping unit has been developed. This pumping unit has many advantages such as small in size, easy to perform long stroke with low stroke times, and convenient to realize automatic control, etc. With consideration of special features of oil and gas recovery in tidal zone around Bohai area, this paper gives a specific analysis and discussion to feasibility of applying hydraulic drive pumping unit in this area.
