液力启动软柱塞抽油泵在出砂区块生产中的应用

Appfication of soft plunger pump with hydraulic start-up in sand producing block

辽河油田的很多区块出砂严重 ,给油田生产带来很多不利因素 ,并大大增加了油田的生产成本。针对这一问题 ,开展了液力启动软柱塞抽油泵的研制工作。现场应用表明 ,该泵具有较好的防砂卡性能 ,同时还具有较高的泵效 ,不仅延长了检泵周期 ,节省了作业费用 ,而且大大提高了油井的单井产量。

Sand producing is a big problem in many blocks of Liaohe oilfleld.It leads to many disadvantages and substantially increases production cost.To solve this problem,soft plunger pump with hydraulic start-up has been developed. Field application shows that this pump is good at preventing sand blocking,has high pump efficiency and longer pump inspection period,saves operation cost,and significantly increases single well production.
