浅谈压裂改造系统工程在大庆杏北油田的应用

SHALLOW ARGUMENT ON APPLICATION OF SYSTEMATIC FRACTURE STIMULATION ENGINEERING IN DAQING XINGBEI OIL FIELD

压裂改造系统工程是以提高油田采收率、保持稳产为目标，从改造区块的整体出发，以欲压裂并为中心，对其注采系统实施最佳改造措施，使油井压裂后达到较理想的生产状态。阐述了对欲压裂改造油藏进行系统分析、系统设计、系统管理和系统评价的方法。该方法在大庆杏北油田的应用，见到了明显的增油效果，对弥补油田产量的自然递减、保持原油稳产起到了重要作用。

Systematic fracture stimulation engineering is a project which is used to im prove recovery and keep production stabilization. Based on the stimulation requirement of a bfock entity, optimum stimulation are run in production and injection system focusing on de sired wells which need to be fractured. An ideal production status is reached after oil well fracturing. The paper giveS a method for systematic analysis, design, management and eval uation to a desired reservoir which needs to be fractured. An oil increment has been shown after the method was used in Daqing Xingbei oil field. It plays a very important role in keep ing oil production stabilization.
