摘要
近年来，四川砂岩油气层酸化工艺技术有了新的突破，开发出新的土酸酸化体系，室内分析进一步充分，对水锁、酸敏以及注液过程中是否对产层产生新的伤害做了大量工作。目前在勘探开发过程中气层均受到伤害，为恢复天然气产能，砂岩储层采用土酸酶化工艺措施是有必要的。文章着重分析了平落坝１０号井影响酸化效果的主要因素及现场应用情况，探索出砂岩储层增产改造措施的可行性方案。
Acidizing technology of sandstone hydrocarbon reservoir in Sichuan has made a new breakthrough in recent years. New mud acid acidizing system is developed. Indoor analysis is done further and fully. Whether water lock,acid sensitivity and inkction do new damages to pay zone is studied. It is necessary to adopt mud acid acidizing technology in sandstone reservoir to resume gas productivity. The main factors and on-the-spot application conditions innuencing acidizing result of Pingluoba well 10 are analyses. The feasible method of increasing sandstone reservoir productivity is proposed out.
