Fixed-Point Multi-Cluster and Optimized Hole Density Perforation Technology Was Successfully Applied in Fuyu Oil Reservoir

摘要: 本文针对扶余油层低孔、超低渗、油层多且薄的特点，开展了改造储层优选，定点多簇射孔、孔密限流压裂探索研究，分析了压裂限流改造机理、岩石力学参数及地应力预测研究、垂直裂缝限流压裂射孔方案优化，在吉林油田扶余油层成功应用并取得好的压裂实施效果，对同类低渗油藏改造具有很好的借鉴意义。

Abstract: Aiming at the characteristics of low porosity, ultra-low permeability, multiple and thin oil layers in Fuyu oil layer, this article carried out the optimization of the reformed reservoir, fixed-point multi-cluster perforation, hole density flow limiting fracturing, and analyzed the fracturing flow limiting reform mechanism, rock mechanical parameters and in-situ stress prediction, and the optimization of vertical fracture low-limiting fracturing and perforation schemes, which have been successfully applied in Fuyu oil layer of Jilin Oilfield and achieved good fracturing implementation effects and have a good reference significance for similar low-permeability reservoirs.
