Abstract: In line with geological characteristics of "low pressure, law permeability and low content of oil and gas" of reservoir in Paleozoic group in Fuxian,Shanbei,and on the basis of investigation and analysis on the data from regional gcaology and testing technology,research on scale optimization and parameters of the multi-step acid fracturing and closed acidizing treatments for different layers has been made. It has deternlined the best implementation scale and parameters, and overall analysis for auxiliary testing techniques such as perforating,testing, gas teesting procedures, liquid flowout after fracturing, pay wne protection have been conducted for the purpose of making quitable testing approach for the exploration in Fuxian area.

Key words: Paleozoic group, oil test, hydrolic-fracturing, acidizing, matching technology, Fuxian area in Shanbei

摘要： 针对陕北富县古生界储层具有“低压、低渗透、低含油气”的三低特点,通过对区域地质及试油工艺资料的调查分析,根据不同岩性储层开展了大型压裂改造及多级注人酸压一闭合酸化工艺技术研究,确定出最佳施工规模及参数,并对射孔、测试、试气制度、压后排液、油气层保护等试油气配套技术进行全面分析研究,制定出适合于富县勘探的合理试油技术措施.
