摘要
Unconventional oil and gas exploration and development have moved from behind the scenes to the stage all over the world.To get a better understanding and make a proper decision,we made a discussion on the E &P history and prospect of unconventional natural gas resources such as tight oil and gas,shale oil and gas,etc.The following findings were obtained.a.In current industrial mining,tight oil & gas,in a broad sense,mainly includes tight sandstone oil &gas,shale oil &gas and coalbed methane(CBM)with the same core exploiting technologies-horizontal drilling and hydraulic fracturing.b.In the USA,exploitation has been extending from tight sand hydrocarbons to coalbed methane and shale gas.The decrease of natural gas prices justified the rapid development of shale oil exploitation in recent years,which makes the USA the fastest growing producer of natural gas and oil.c.The upto-date survey indicates that shale oil and shale gas account for 10% and 32% respectively of the global cumulative assessed hydrocarbon reserves.d.Tight liquids,an outstanding and popular concept worldwide in recent years,are mainly of shale oil including Natural Gas liquids(NGLs)and Light Oil.It suggests that only relatively light oil can be exploited out of tightly reserved oil.Accordingly,it could be named Light Tight Oil or LTO.
