去年,联邦德国力士乐油压器材公司(S.L. Rexroth Ltd.)生产了一种液压抽油机,销往委内瑞拉油田使用。这种抽油机采用长液缸驱动井下抽油泵进行采油,其结构和性能完全不同于常规式的游梁抽油机。该抽油机外形如图所示。全机由底座、机架、托架、液压系统等四个主要部分组成。工作时的总体尺寸为:长9.6米、宽2.4米、高14米。在移运时将机架拆叠放倒,高度降至2.5米左右。与常规式游梁抽油机相比较,这种液压抽油机有以下几个特点: 1.采用液压驱动方式,有较大的灵活性和
Last year, S.L. Rexroth Ltd. produced a hydraulic pumping unit for use in the Venezuelan oil fields. This type of pumping unit uses a long-cylinder-driven downhole pump for oil recovery. Its structure and performance are completely different from the conventional beam pumping unit. The pumping unit shape as shown. The whole machine from the base, rack, bracket, hydraulic system composed of four main parts. The overall dimensions of the work: 9.6 meters long, 2.4 meters wide, 14 meters high. The rack will be tumbled down and moved to a height of about 2.5 meters. Compared with the conventional beam pumping unit, this hydraulic pumping unit has the following characteristics: 1. Using hydraulic drive, with greater flexibility and
