常规抽油机改造成旋转驴头抽油机性能测试

针对我国陆地各主要油田人工开采的现状及常规采油设备存在的问题，提出了对常规抽油机进行增程改造的依据、方案及基本内容，并以CYJ10－3－53HB型常规抽油机改造成CYJ10－4．2－53HF（改）型旋转驴头抽油机为例，介绍了改造机的试制情况。按照GB11649－89《游梁式抽油机》及SY5212—87《游梁式抽油机质量分等》标准，对改造机承载时主要构件的应力、支架晃动度、悬点投影、噪音及电参数等进行了严格测试。测试结果和现场试验表明，改造机不仅具有一定承载能力，使用方便，可靠性高，而且增产、节能效果显著。与常规机相比，日产液量提高12％以上，每吨液成本降低8％以上。

Test of performance of pumping unit with rotary horsehead

The basis, scheme and procedures for inereasing the stroke of a conventional pumping unit are presented. ModelCYJZ10 - 4. 2 - 53HF pumping unit with rotary horsehead is developed based on Model CYJ10 - 3 - 53HB pumping unitaccording to the above-mentioned procedures. Some of the key performances of the main component parts of the new unitare tested strictly. The test and the service of the unit show that the pumping unit with rotary horsehead had high loadbearing capacity and reliability, and by using it, the well fluid production per day can be increased by more than 12 per-cent and the cost of a ton of produced fluid can be redueed by over 8 pereent.
