摘要
现河低渗油区由于油层物性差 ,天然能量不足导致油井自然产能低 ,为了提高该类区块的整体开发水平 ,必须依靠油层改造措施。以室内实验、现场监测为指导 ,借鉴国内外先进增产技术设计思路 ,进行水力压裂施工方案优化设计。经现场 80余井次的应用 ,取得了平均单井日增油 10 2t,平均增产比 2 67的良好效果 ,3a实现累计增产 16× 10 4 t,使压裂工艺成为现河低渗油区连续
Xianhe low permeability oilfield met low primary productivity because of poor physical properties of formation and inadequate natural energy. To improve development level of the whole block, formation transformation measures must be adopted. Instructed by indoors experiment and site supervision, incorporating advanced production enhancing scenarios around the world, hydraulic fracturing schemes optimization is performed. More than 80 times site application has achieved average oil production increment of 10.2 t/d ( 2.67% per day and totaling 16×10 4 t for the past 3 years). This illustrates that fracturing technique is one of the effective measures in stabilizing production of Xianhe low permeability oilfield for 3 continual years.
