摘　　要：以长X为代表的致密油藏储量大,分布稳定,是长庆油田5 000×104t上产、稳产的重要接替资源。该类油藏由于储层致密、物性差,前期改造效果差,提高单井产量难度大。近年来,体积压裂技术的成功运用,使得国外致密油气藏获得成功开发。文章阐述了通过理论研究,结合压裂监测、测试压裂分析、压后产量等分析手段,优选了压裂液体系、合理组合压裂配套工具和优化了压裂工艺参数,在国内首次探索性地开展了混合水体积压裂技术攻关试验,取得了成功和较好的效果,为鄂尔多斯盆地致密砂岩油藏的有效改造开辟出一条新途径。The reserves of tight sandstone reservoir of Erdos basin are very rich,but the reservoirs is characterized by tight,low permeability and poor reconstruction effect in early stage,improving the single well production is difficult. In recent years,the volume fracturing technique has been applied successfully in tight oil and gas reservoir abroad. Through theoretical study and combining with the fracturing monitoring,fracturing test analysis and post- flush production analysis,optimizing the fracturing fluid system, fracturing tools and fracturing parameters, the mixed water volume fracturing technique was developed for the first time in China,and used successfully in tight sandstone reservoir of Erdos basin,and good results have been achieved.
