纳维泵+MFE阀组合工艺介绍

Introduction of the Make up Technology NAVI pump＋MFE valve

用纳维系＋MFE阀组合测试工艺，既可使用纳维泵进行排液求产，也可进行井下关井测地层恢复压力，求取地层参数。纳维泵对地层液体要求不严格，携砂能力强，一般地层供液能达到400m（动液面距井口的高度），且地层供液充足，就可以采用该工艺。文中同时介绍了两口井的施工实例。

Using the NAVI pump+MFE valve makeup test technology can reach two goals at one time,one is that the NAVI pump can be used to test the production rate,another is that the pressure buildup test data by shutting the well at the down hole. NAVI pump is not strict for formation fluid,it has high propcarrying capacity. If the formation fluid can reach to 400m high in the wellbore (producing fluid level above the down hole),and the formation energy is high enough,this kind of technology can be used. Two examples were given in this paper.
