裂缝型碳酸岩盐储层评价的关键参数是裂缝孔隙度 ,用常规测井资料评价低孔 裂缝型碳酸盐岩储层一直停留在定性识别的范围内。该研究在定性识别的基础上 ,用岩心刻度测井的方法计算了某气田裂缝型碳酸岩盐储层的裂缝孔隙度 ,在常规测井资料极其有限的情况下 ,取得了比较理想的效果 ,提高了测井解释的精度 ,从而为此类储层的测井定量评价提供了一种思路和有效的方法。测井资料严重缺乏是许多老气 (油 )田面临的一大难题 ,因此 ,该方法在老气 (油 )
The key parameter in evaluating fractured carbonate reservoirs is fracture porosity. However, the evaluation of such reservoirs with conventional logging data has for the most part been qualitative. On the basis of qualitative identification, the fracture porosity of the Changxing fractured carbonate reservoir in the T gas field was determined in the present work, by calibrating log curves with core data. Results indicate a higher log interpretation precision although available log curves were much limited. Considering the situation in many of the old oil/gas fields where log data are extremely inadequate, it is believed that the proposed method is promising in application.
