大庆探区深层特殊岩性储层压裂改造技术

Fracture Treatment Technology of Special Lithology Reservoir at Deep Layer in Daqing Exploration Area

以往大庆探区深层特殊岩性储层压裂效果不佳。通过全面分析复杂岩性深层压裂增产的技术现状,找出了深层砂砾岩储层压裂无高产、火山岩储层压裂施工成功率低的原因。逐步配套完善的大庆探区深层特殊岩性储层增产技术,在大庆探区深层砂砾岩及火山岩储层进行推广应用,见到了显著效果。

The fracturing effect to special lithology reservoir at deep layer deep in Daqing exploration area is not good before. Through analyzing the present technical situation of increasing oil yield by fracture of deep layer with complex lithology, it can be searched out the cause of being without high yield deep for deep glutinite reservoir fracture and low execution success ratio of volcanic rock reservoir compression fracture. The tech of increasing production for deep lift special lithology reservoir is consummated gradually in Daqing exploration area and is applied in deep glutinite and volcanic rock reservoir at deep layer and achieves visible effect.
