随着油田开发的深入,原有的计量模式难以适应生产管理的需要。目前油井产量计量方法主要有玻璃管、流量计等计量方法,但都普遍存在着应用装置多、工艺流程过长、投入较多等问题,难以适应地面系统简化优化的要求。因此,利用抽油机井示功图计算油井产量的技术进一步得到了认识,并逐步得到了应用。 With the deepening of oilfield development, the original measurement model is difficult to adapt to the needs of production management. At present, oil well production measurement methods are mainly glass tube, flow meter and other measurement methods, but there are many applications such as the widespread application process, the process is too long, more investment and other issues, it is difficult to adapt to the ground system to simplify the optimization requirements. Therefore, the technique of calculating the well production by using the dynamometer well diagram has been further recognized and gradually applied.
