摘要
千16-16井为大港油田千米桥潜山第1口大斜度井,分析了高温深井裂缝发育储层酸压的技术难点,筛选出适合于该地区大型酸压改造的酸液体系,优选了酸压工艺和施工参数,并应用了油套双限压注液方式,使大规模超大排量酸压得以实现,并取得良好实施效果。为今后该地区酸压工艺的实施开辟了一条技术创新途径,也为千米桥油田规模化开发提供了技术储备。
Well Qian 16-16 is the first high deviated well in buried hill Qianmiqiao in Dagang Oilfield.To overcome the technical difficulties of acid fracturing in facture developing reservoirs of high-temperature deep wells,the acid fluid system suitable for this region was screened out,and acid fracturing technology and operating parameters were optimized.Separated tubing and casing pressure limit injection method was innovatively used to achieve the large scale displacement of acid fracturing. And good results were achieved.It opened up a new way of technology innovation for acid fracturing in this region and provided technical storage for the large-scale development of Qianmiqiao Oilfield.
