摘要:

准噶尔盆地火山岩地层评价十分复杂,一方面,单一依靠某种测井资料识别岩性暴露出越来越多的局限性,另一方面,利用常规测井方法评价储层裂缝、孔隙具有很大不确定性。本研究方法在岩芯刻度的基础上,结合FMI、ECS测井资料对火山岩岩性进行结构、成分综合识别,对火山岩喷发旋回进行划分;在此基础上还对裂缝进行识别,对裂缝参数、孔隙频谱进行计算分析,体现了FMI、ECS测井在火山岩评价中的独特优越性,取得了非常好的应用效果。

Abstract:Evaluation of volcanic reservoirs in Junggar Basin is very complex.On one hand,the limitation of lithology identification based on single logging data is more and more obvious.On the other hand,the evaluation of fractures and pores based on conventional logs is unstable.Based on the calibration with core data,lithology can be identified according to different structures and chemical contents combining FMI with ECS data.Hence,the eruption cycle can be classified,fractures can be analyzed qualitatively and quantitatively,and pore structure can be characterized.The method which combines FMI and ECS has shown its unique advantages in volcanic reservoir evaluation and has achieved great success in Junggar Basin.
