KR-01射孔保护液的开发与应用

油井补孔投入新的储量开采是油田挖潜增产中最频繁而重要的措施,中原油田大部分地层水矿化度高达4.31-30×104m g/L,且油层属中、强水敏地层,因此完井液质量直接影响补孔油井产量。文中介绍了KR-01射孔保护液的实验性能及在中原油田采油三厂补孔措施中的应用效果。现场应用及试井分析资料显示,采用KR-01射孔保护液措施井表皮系数小于零,有效的防止了油层污染,保护并改善了储层物性。

The Development and Application of KR-01 Perforating Fluid

Reperforating is the most important and frequent measures to develop reserves.The formation water salinity in most of reservoirs is 4.31-30×104mg/L,and the pay zones are medium or strong water sensitivity.So, the quality of perforating fluid will influence the production of the well with perforating measures.This article introduces the laboratory evaluation and field application of the KR-01 perforating fluid.The field application and testing data indicate that it can prevent contamination and improve the p...
