摘要: 依据大庆外围已开发扶杨油层油藏的地质特征和注水开发动态特点,研究了低渗透储层有效驱动体系、裂缝基质系统渗流特征、裂缝储层水驱油特点、裂缝储层渗吸法采油机理。应用矿场资料求取启动压力梯度,建立了有效驱动模型。在此基础上,以提高扶杨裂缝性油层有效动用为核心,进行了线状注水方式和井网加密调整的研究。将这些技术用于大庆外围扶杨油层的注水开发调整,提高和改善了外围油田的开发效果。

Abstract: According to the geologic characteristics and waterflood development performance of the exploited Fuyang Formation in the periphery of Daqing Oilfield, the effective driving energy system in low-permeability formation, the fluid flow properties of fracture-matrix system, displacement characteristics of waterflood development of fracture formation, and oil production mechanism of imbibitions process were investigated. The starting pressure gradient was achieved using field data. The effective drive model for oil displacement was developed. The line water injection and well pattern infilling technologies for improving the exploitation effectiveness in the periphery of Daqing oil field were discussed.

Key words: Daqing Oilfield, low-permeability reservoirs, fractured reservoir, waterflood development, drive model, injection-production system, well pattern infilling technology
