摘要
辽河油区欢西油区稠油区块层内出水问题严重、油井吞吐效果差,为此,在采出程度低的稠油高含水井上探索不注汽直接应用螺杆泵冷采的可行性,并结合现场应用情况,浅析了增油机理。在锦45块和锦611块等区块部分高含水井上应用螺杆泵采油技术,采用变频控制柜控制合理的生产压差,取得了较好的降水增油效果,投入产出比为1.0:5.2。
Huanxi heavy oil block in Liaohe oil province has serious water breakthrough problem and poor cyclic steam stimulation effect.Hence the feasibility of screw pump cold production without steam injection has been studied in high water cut heavy oil wells with low degree of reserve recovery.The mechanism of enhancing oil production has been analyzed combining with field application. Screw pump oil recovery technique has been applied in some high water cut wells in Jin 45 and 611 blocks,producing pressure drop has been properly controlled by using frequency conversion control box,the result of decreasing water and increasing oil has been obtained,and the input/output ratio is 1.0:5.2.
