摘要
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 sandbodies in Shengli oil field are at new stratigraphic time, buried shallowly, of poor rock forming property in reservoirs, loosely consolidated and highly clay contained. So the protection to gas-bearing formations is much important. The main factors of the damage in the formations in drilling, perforation, operation and development are analyzed and the corresponding safeguards are suggested in this paper. It is also pointed out that the protection technologies play an important role in finding gas reservoir in time, improving the individual-well production, increasing ultimate recovery factor and reducing production cost.
