胜利油田气砂体地层年代新、埋藏浅、储层成岩性差、胶结疏松、粘土含量高 ,气层保护尤为重要。该文分析了钻井、射孔、作业和开发生产中气层伤害的主要因素 ,并提出了针对性的保护措施。指出气层保护技术对及时发现气藏、提高单井产量、提高最终采收率、降低开采成本起着极为重要的作用。 The gas sand body of Shengli Oilfield has a new age, shallow burial depth, poor diagenesis of the reservoir, loose cementation, high clay content and protection of the gas layer. This paper analyzes the main factors of formation damage in drilling, perforation, operation and development and production, and puts forward some protection measures. It is pointed out that the technology of gas reservoir protection plays an extremely important role in discovering gas reservoirs in time, increasing single-well production, improving final oil recovery and reducing mining costs.
