摘要
分析了克拉美丽气藏滴西18井区的储层特征,通过对石炭系气藏压裂的难点分析,探讨了前置液段塞技术、提高前置液比例、采用较大的施工排量、变排量工艺、小阶梯砂比加砂工艺等压裂改造技术,同时研制出适合低渗致密气藏压裂改造的防水锁压裂液体系,这些技术的应用保证了滴西184井压裂改造的成功实施。
The reservoir characteristics of Dixi 18 well block in Kelameili gas reservoir has been analyzed in this paper.Through the Carboniferous gas reservoir fracturing difficulties analysis,the prepad slug technology in has been discussed,which improves the preflush percentage,adopts greater flow rate,fracturing technology with alteration discharge capacity,increases sand fluid ratio with small step,and so on.At the same time,the fracturing fluid system for low permeability tight sand gas accumulation has been developed and provided successful experience for the same gas well fracturing accumulation.
