摘要
抽油井井口回压过高将对深井泵造成不利影响,使深井泵漏失量增大,减小泵效,缩短检泵周期。为此研制了KZW型有杆增输泵,介绍了增输泵的理论基础、工作原理、主要技术参数和优点,通过现场应用,取得了较好的效果,具有较好的推广价值。
<Abstrcat>?Higher back pressure has bad affection for deepwell pump,such as wastage increasing, pump efficiency reducing,maintenance period reducing,so the KZW type increment pump is developed In this paper , the increment pump theory base,working theory,main technical parameter and advantage are introduced
