射流泵举升技术预测低渗油田产能的应用和评价

Application and evaluation of jet pump lifting technology for predicting productivity in low permeability oil fields

通过实际应用案例和效果分析,射流泵返排工艺针对低渗、深井、凝固点高,温度高的储层有很好的经济性、操作性及可靠性,同时对射流泵返排效果提高参考,对返排过程中实时预估生产压差、产能情况提供借鉴,对油藏对地层产能辅助判断提供依据。

In this paper,through practical application cases and effect analysis,the jet pump flowback process has good economy,operability and reliability for reservoirs with low permeability,deep Wells,high freezing point and high temperature.At the same time,it provides reference for improving the flowback effect of jet pump,real-time prediction of production pressure difference and productivity in the flowback process,and provides basis for auxiliary judgment of reservoir and formation productivity.
