石油钻井泥浆泵是钻机中最关键的设备之一,被称为钻井的“心脏”。我局使用的罗马尼亚F系列钻机是七十年代初期的产品,配备双缸双作用泥浆泵。双缸双作用泥浆泵同三缸单作用泥浆泵相比,在泵的结构和性能上都存在着无法解决的问题,如液力端结构复杂,体积大,压力波动大,排量不均匀,机械效率低,等等,不能满足目前喷射钻井工艺的需要。 喷射钻井工艺要求必须采用高泵压、大功率泥浆泵,以提高钻井速度,降低钻井成本和 Oil drilling mud pump is one of the most critical equipment in the drilling rig, known as the “heart” of drilling. The Romanian F-series drilling rig used by our bureau is a product from the early 1970s, equipped with a double-action double acting mud pump. Compared with the single-action mud pump with triple-cylinder, double-action double-action mud pump has unsolved problems on the structure and performance of the pump. For example, the structure of the hydraulic end is complex, the volume is large, the pressure fluctuation is large, Low mechanical efficiency, etc., can not meet the needs of the current jet drilling process. Jet drilling requires the use of high-pressure pump, high-power mud pump to improve drilling speed and reduce drilling costs and
