摘要
油井出砂是砂岩油藏开采过程中的一个常见问题，出砂不仅易造成油井的减产、停产，而且严重时会造成套管的损坏和油井报废。因此，要确保油井的连续稳产，就必须采取一些有效的措施来解决油井的防砂问题。防砂技术需防、挡、排几项技术综合利用，动筒式防砂泵具有防砂卡、防砂磨、防砂埋、自冲洗等特性，使用该泵可以更有效的防止泵的砂卡和泵漏，及时排出井筒细粉砂，降低油井开采成本的同时可有效保证油井连续生产。
Sand production is a common problem in the mining process of sandstone reservoir, which not only causes production reduces and halts, but also causes serious casing damaged and well abandoned. Therefore, in order to ensure continuous and stable well production, it is necessary to take some effective sand control measures. Sand Control technology uses prevention, blocking and discharging sand together. The features of dynamic tube sand control pump, such as preventing the sticking, milling, burying of sand and washing itself, enables the prevention of sand sticking and pump leakage and timely discharge shaft fine sand more effectively. This method reduces the cost of mining, while ensures continuous nroduction of well.
