摘要
针对文33块沙三上段低渗透油藏的开发特点,在分析剩余油和地应力分布规律的基础上,研究注采井网与水力裂缝系统的优化组合,优选适合该油藏整体压裂的水力裂缝参数,部署整体压裂方案。通过现场应用,提高了区块采收率,减缓了综合递减和自然递减,获得了高效开发效果。
In accordance with the exploitation feature of low permeability reservoir in upper Es_3 of Wen33 block,systematic fracturing project is deployed on the basis of the study of remaining oil and earth stress distribution and the optimum configuration of injection-production pattern and hydrodynamic fracture system.The hydrodynamic fracture parameters suitable to the project are selected.As a result,oil recovery factor is enhanced,both composite and natural decline are reduced,and efficient development response has been achieved.
