114mm大孔径高孔密防砂射孔器在胜利油田的应用

, Applications of 114 nun Big Hole & High Perforating Density and Sand Control Perforator in Shengli Oilfield

如何在不影响油井产能的情况下有效地控制油井出砂成为射孔防砂技术的关键。胜利油田测井公司开发研制出一种114mm大孔径高孔密防砂射孔器,能在射孔的同时起到防砂的作用。它适用于出砂层和稠油层射孔;配合防砂材料进行高压填充,防砂效果更为明显,因此,提高了油井产量,降低了采油成本。

How to effectively control sand flow in the oil wells is a key technology in sand control operations. To solve this problem, Shengli Logging Company has developed a 114 mm big hole & high perforating density and sand control perforator. This perforator has the ability to control sand flow while perforating, so it is applicable for perforations of sand-bearing layers and viscous oil beds. Its sand control effect is much better when high pressure filling is made along with sand control materials, hence increasing oil productivity and reducing recovery cost.
