基于测井响应的煤体结构识别及开发效果评价
Coal body structure identification and development effect evaluation based on logging response
-
摘要: 根据不同煤体结构的测井响应特征,对研究区的煤体结构进行定量识别、精细描述,通过钻井取心结果进行验证,利用单层产气效果和每米煤厚的产能贡献指标,对研究区不同煤体结构煤层的开发效果进行评价并提出开发建议。结果表明:测井响应的补偿声波、补偿密度及井径测井值得到的煤体结构指数可以对煤体结构进行定量识别,研究区煤体结构指数小于500为原生结构煤,大于600为构造煤;研究区内Y1井原生结构煤、碎裂煤每米煤厚的产能贡献为600~1 200 m3/m,构造煤的产能贡献低于500 m3/m,产能贡献随着煤体结构指数的增加而降低;在目前的开发技术条件下,不适宜直接对构造煤进行煤层气开发。Abstract: According to the logging response characteristics of different coal structures, this paper quantitatively identified and described the coal structure in the research area, verified the results by drilling and coring. By using the single layer gas production effect and the productivity contribution index of per meter of coal thickness, the development effect of different coal structure coal seams in the research area is evaluated and development suggestions are proposed. The results show that: the coal structure index obtained from the compensation acoustic wave, compensation density and borehole diameter logging response can be used for quantitative identification of the coal body structure, the coal structure index less than 500 is the primary structure coal in the research area, and more than 600 is the tectonic coal; the productivity contribution of primary structural coal and cataclastic coal per meter of coal thickness in well Y1 in the research area is from 600 m3/m to 1 200 m3/m, while that of tectonic coal is less than 500 m3/m,the productivity contribution decreases with the increase of coal body structure index; under the current development technology conditions, it is not suitable to directly develop CBM from tectonic coal.
