欧利坨子地区火山岩储层测井评价

Well logging evaluation of the volcanic reservoirs in Oulituozi Area of Liaohe Basin

由于火山岩储层具有裂缝—孔隙型双重孔隙结构特征,导致有效储层识别难度大。从火山岩岩石物理特征研究入手,以常规数控测井和成像测井技术为手段,建立火山岩不同岩性及储层与测井响应的对应关系,通过采用测井交会图法,有效地识别出研究区火山岩不同的岩性及储层,总结出适合地区特点的火山岩储层测井评价方法。

Due to the characteristic of double pores system of fractures and porosity in volcanic reservoirs, it is much more difficult to identify the effective reservoirs. Starting with analysis on petrophysical features of volcanic reservoirs, and using conventional computerized logging and imaging logging techniques, the paper sets up the corresponding relations between reservoirs, volcanic lithology and logging responses., and by using well logging crossplots, to identify effectively different volcanic lithilogy and reservoirs, and finally summarizes a set of well logging evaluation methods of volcanic reservoirs for the study area.
