利用QS盆地ZZ区块成像测井资料开展区域煤层气测井综合评价,从煤层的顶底板质量、煤层的内部结构、裂缝发育状况、地质构造、区域煤层含气量的变化情况等方面进行了综合分析,得到区域变化规律,将区域煤层与顶底板特性综合起来形成一个完整的煤层系统,按其性质优劣划分成3个级别,从而进行煤层气勘探开发有利区带的预测.分析结果得到了区域实际煤层气量的证实.
利用QS盆地ZZ區塊成像測井資料開展區域煤層氣測井綜閤評價,從煤層的頂底闆質量、煤層的內部結構、裂縫髮育狀況、地質構造、區域煤層含氣量的變化情況等方麵進行瞭綜閤分析,得到區域變化規律,將區域煤層與頂底闆特性綜閤起來形成一箇完整的煤層繫統,按其性質優劣劃分成3箇級彆,從而進行煤層氣勘探開髮有利區帶的預測.分析結果得到瞭區域實際煤層氣量的證實.

The well logging comprehensive evaluation is one of the important job to evaluate coalbed methane resource. The evaluation contents in ZZ area in QS basin includes: the cover quality of the roof and floor, the coal seam inner structure, the fracture growth situation, geologic structure,gas content,etc., from which the area variation law is derived. The synthesized area coal seam and roof-floor property forms an entire system. Three ranks according to the system's character partition superior or inferior are defined to carry out the interesting CBM forecasting. And the analysed result has finally got actual CBM production tolerance.
