摘要
"连续油管压裂技术"是在传统压裂的基础上,通过引入连续油管实现"一次多压"的目标,从而达到"大型压裂,迅速增产"的目的。文章针对合川须家河组及红河油田长8油藏水平井低孔低渗、油水关系复杂、勘探开发难度大、后期出水严重等特点,为了经济有效地开发该类油气资源,提出采用连续油管分段压裂技术,在分析压裂效果影响因素的基础上,优化推荐了压裂方案。通过合川区块和HH37P116井的现场试验,最终实现了水平段多段压裂以及油井的增产目标。该技术的成功实践为今后连续油管分段压裂技术的发展应用起到了一定的参考和借鉴作用。
'Coiled tubing fracturing technology'based on traditional fracturing introduces coiled tubing to realize the goal of multiple fracturing and reach the purpose of large fracturing and rapid increase. Xujiahe formation in Hechuan Area,Sichuan Basin and Chang 8 reservoir horizontal well of Honghe oilfield have the characteristics of low porosity,low permeability,complex oil- water relationship,difficult exploration and development and serious water in the later period. To develop this kind of oil and gas resources effectively and economically,the coiled tubing staged fracturing technology was applied,and the fracturing plans were optimized based on analyzing the factors of influencing the fracturing effect. By testing in Hechuan area and well HH37P116,the goal of staged fracturing and increase production were achieved.
