摘　　要：由于胜利油田深层含气储层复杂的地质条件,需要解决识别与增产两道难题。文章探讨了胜利油田在深层试气工艺上,采取负压深穿透射孔技术,根据应力分析优化射孔井段,有效控制缝高,提高压裂效率;测试优化开关井时间,采取加N2垫,针对特低渗透储层的特点,引进CO2增能大型压裂技术,利用CO2强化排液,这些技术有效地解决了识别储层的难题,对复杂地层做出准确评价。As the deep gas-bearing reservoir in Shengli oil field has its complex geological conditions,We need to solve two problems-recognition and increasing production.In this article,We discuss that in the gas process test in Shengli oil field,we take deep-penetrating perforating technology of the negative pressure to control high pressure slit and improve the efficiency of fracturing.We take advantage of mat N2 to test and optimize the time of well switch.We introduce increased large-scale fracturing technique of carbon dioxide,which effectively solves the difficult problem of identifying reservoir and evaluates complicated stratum accurately.
