水力喷射泵采油是 2 0世纪 90年代初研制成功的一种采油新工艺 ,1994年通过ISO90 0 1质量体系认证 ,主要适用于稠油井、出砂严重及偏磨、腐蚀严重的油井。 1998年 3月开始在垦西油田K71断块实施该工艺 ,目前有管网式水力喷射泵井 2 7口 ,与常规机械采油相比 ,垦西油田油井免修期由 110d延长到 35 0d左右。介绍了管网式水利喷射泵采油工艺及其在垦西油田的实施效果。
Hydraulic jet pump is a new oil recovery technology successfully developed in the early 1990s. It passed the ISO90001 quality system certification in 1994. It is mainly applied to heavy oil wells, serious and unscreened sands, and serious corrosion. In March 1998, K71 fault block in Kenxi oilfield was started to implement this process. There are currently 27 pipe network hydraulic jet pump wells. Compared with conventional mechanical oil recovery, the oil well maintenance free time in Kenxi Oilfield is extended from 110d to 35d. The production technology of pipe network water jet pump and its effect in Kenxi Oilfield are introduced.
