在加拿大阿尔伯达省落基山脉的丘陵地带有几个开采的气田位于剧烈冲断层形成的圈闭中,该区以冲断层为特征,密西西比岩石(下石炭统)中发现了天然气,气藏埋深为3—6km,且距落基山脉的山前越近埋深越大,该区露头岩石是白垩纪砂岩及海源和陆源的页岩。整个地区为保留林带,与阿尔伯达省的其它油气田开采区不同,该区没有工农业电噪音(管道、输电线、电子围墙等),由于无电噪音,使得该区成为确定气藏能否产生用地面电法可以检测的电性异常的理想区域。
In the hilly region of the Rocky Mountain, Alberta, Canada, several mined gas fields are located in the trap of violently thrust faults characterized by thrust faults. Natural gas and gas pools were found in the Mississippi rocks (Lower Carboniferous) The burial depth is 3-6km, and the more buried depths are from the front of the Rocky Mountain, the outcrop rocks in this area are Cretaceous sandstone and shale of sea and land source. Unlike the other oil and gas extraction areas in Alberta, the entire area is reserved for belts and there are no industrial and agricultural electrical noise (ducts, power lines, electronic enclosures, etc.) and no electrical noise makes the area a natural gas reservoir An ideal area for electrical anomalies that can be detected by terrestrial electrical methods.
