腰英台油田腰西区块青二段气藏研究

Study on the qinger member gas reservoir in Yaoxi block of Yaoyingtai Oilfield

腰英台油田腰西区块DB33井区2005年投入开发,2006完成产能建设,主要生产层位青一Ⅱ和青二Ⅳ,流体性质为原油。2006年9月4日-9月9日对DB33-5-5井青二Ⅱ砂组2092.2~2093.7、2098.8~2101.6井段压裂测试,生产时间89.5h(1.5天),累计产气7.085×10^4m^3;2006年10月5日-11月1日对DB33-9-3井青二Ⅱ砂组2080.5~2085.2井段常规测试,生产时间35.5h(3.7天),累计产气1.767×10^4m^3,发现了青二Ⅱ气藏。因此对DB33井区107口井青二段进行研究,利用老井测井资料与最新的测井技术进行测井二次解释,新解释气层98层,并对DB33-5-3新解释气层测试,取得工业气流,效果良好。

Db33 well block in Yaoxi block of Yaoyingtai oilfield was put into development in 2005,and production capacity construction was completed in 2006,The main production horizons are Qingyi Ⅱ and qinger Ⅳ,and the fluid property is crude oil.From September 4 to September 9,2006,fracturing test was conducted on well db33-5-5 in well block 2092.2-2093.7 and 2098.8-2101.6,The production time is 35.5 hours (3.7 days),and the cumulative gas production is 1.767 × 104m3.Qinger II gas reservoir is found.Therefore,107 wells in db33 well area are studied in qinger formation,and the old well logging data and the latest logging technology are used for logging secondary interpretation,98 layers of newly interpreted gas reservoir and db33-5-3 new interpreted gas reservoir are tested,and industrial gas flow is obtained with good effect.
