摘要
松滋油田红花套组储层在钻完井过程中泥浆、固井液对地层存在着污染,影响产能。通过酸化可以解除污染,提高水平井产能;但常规酸化面临着水锁伤害严重、油层非均质性强、返排速度慢等问题,通过工艺上采用的针对性措施,较好的应用于了现场,并取得了良好效果。
During the drilling operations of Honghua formation reservoirs,Songzi Oil Field,mud and well cementing fluid often pollute stratums and cause a decrease in production capacity.Though the pollution and capacity problem can be solved by acidification,conventional acidifying efforts are often challenged by other problems such as severe consequences of water blocking,high heterogeneity in oil reservoirs and slow flowback,etc.This paper had devised corresponding techniques to address the problems and achieved desired effects in practice.
