摘要
理论分析和油田现场钻井实践表明,钻井液中液相及固相颗粒侵入裂缝是造成裂缝性气藏储层伤害的主要因素。本文阐述了裂缝储层损害机理,系统介绍了保护裂缝性储层的钻井液技术。
Theoretical analysis and field application suggest that the invasion of liquid and solid of drilling fluids into fractures are the main factors for damage to fractured reservoir.The mechanism of formation damage for fractured reservoir and various drilling fluids used for formation protection are systematically introduced in this article.
