摘要
针对松辽盆地北部火山岩地质特征,采用火山岩储层压裂风险预测技术、测试压裂现场快速解释技术、火山岩储层水力压裂裂缝延伸控制技术的火山岩储层压裂优化设计方法,以及火山岩压裂施工工况分析、判断和现场实时控制方法,同时针对火山岩储层温度高、施工时间长、施工压力高的特点,通过研制耐高温、耐剪切压裂液体系、井下工具压裂管柱以及地面排液和效果评价系统等,进行了技术配套,初步形成了松辽盆地北部深层火山岩气藏的压裂增产改造技术。
To meet the geological characteristics of volcanic rock in the northern part of Songliao Basin, fracturing risk prediction technology for volcanic rock reservoir, rapid interpretation technology on the fracturing site and controlling technology of the hydraulic fracture extension for volcanic rock reservoir are adopted to design optimization of fracturing volcanic rock reservoir. Based on the analysis and judgment of volcanic rock fracturing operation as well as the real-time on-site controlling methods, a series of technology has been developed in the light of the high temperature, long operational time and high pressure of volcanic rock fracturing, including the high-temperature resistant and shear resistant fracturing ?uid system, downhole fracturing pipe string, surface ?uid discharging and result-appraising system. The stimulation technology for deep-layer volcanic rock gas reservoirs in the northern part of Songliao Basin is preliminarily shaped at the present time.
