基于测井数据的页岩气预探井评价研究

Evaluation Research of Shale Gas Pre-exploration Wells Based on Logging Data

随着数字测井技术的不断应用,其在页岩气勘探中发挥着越来越重要的作用。对武威盆地某页岩气预探井进行了地球物理测井分析和研究,根据测井资料,划分了地层界面,结合岩芯录井和气测录井资料,综合研究表明,岩电特征明显,但是目的层位整体含气性较差。这为该区页岩气储层识别评价和预测提供了较为可靠的地质参考依据。

As digital logging technology continues to apply,it plays a more and more important role in shale gas exploration.Geophysical logging analysis and research have been carried out for a shale gas pre-exploration well in Wuwei basin.According to the logging data,the formation interface has been divided,combined with the core logging and gas logging data,the comprehensive study shows that rock electrical characteristics are obvious,and the whole gas bearing capacity of the target layer is poor.It provides a reliable geological reference for shale gas reservoir identification,evaluation and prediction in this area.
