| 摘 要： | 由于松辽盆地北部深层火成岩气藏储层岩性复杂、储层孔隙类型复杂等原因,用常规测井资料评价火成岩储层存在许多困难,而核磁共振测井则为解决该类问题提供了另一种有利的手段。利用核磁共振测井的横向弛豫时间T2分布谱可直接反映岩石孔隙半径大小的特点对深层火成岩储层类型进行了划分,其结果与成像测井图表现出很好的一致性。另一方面,对储层的有效性进行了评价,为建立火成岩储集层划分标准提供了依据。

| Abstract: | Due to complex lithology and various pore types of the deep volcanic rock gas reservoir in north Songliao basin,it is difficult to evaluate volcanic rock reservoirs with conventional logging data evaluation.But NMR logging provides a new method to solve this kind of problems. With NMR characteristics that transverse relaxation time T_2 distribution can reflect pore radius directly,deep volcanic rock reservoirs are classified.The result shows good consistency with imaging logging graphs.On the other hand,the... |
