Shale oil and gas ≠ shale gas shale oil +

China's oil and gas industry saw a " shale oil " is , this description is mined from shale gas and shale with this symbiosis, associated shale oil . " Shale gas " read together fluently ,Ceramic proppant in fact, the basic concepts confused confusion . First, shale gas extraction from shale , there are symbiotic with shale gas , associated crude production, be mistaken for shale oil , in fact, dense oil. Currently people on shale oil, tight oil has a different understanding of the meaning , so the shale oil and tight oil in the use of terminology misunderstanding and controversy. Shale and tight rock in scientific research , it will be divided into broad and narrow shale oil , tight oil also will be divided into broad and narrow , but in practice, the two meanings of concise , making it easy to understand. Tight oil and shale oil are both unconventional oil , because of its dense reservoir permeability is extremely poor with conventional technology can not achieve economic development . Tight oil , is in English "tightoil" Chinese translation ,frac proppant also known as light tight oil , shale gas in the production zone of the use of horizontal drilling and multi-stage hydraulic fracturing to produce mature oil . From the dense layer and mined oil shale are tight oil . The shale oil corresponding English is "shaleoil", is produced from oil shale oil , also known as kerogen oil , is stranded in the crude oil source rocks , without the migration of immature oil . Oil shale must be heated through artificial hydrogenation by distillation of crude oil extracted from oil shale is similar , also known as synthetic oil . Dense oil in the oil quality the same as the conventional reservoir , all belong to light crude oil and shale oil is a heavy oil , which is the difference between the API gravity and viscosity difference and extracted in different ways. Two different production locations , tight oil from underground mining , and oil shale retorting on the ground . Tight oil need to use horizontal drilling and multi-stage fracturing technology in order to achieve economic exploitation, and shale gas production in the same way . The main use of the ground retorting oil shale production method , production can be divided into internal combustion , thermal cycling solid France , next door to the heat transfer method, an external injection of hot gas , reaction fluid method for internal combustion -based, China's use of Fushun distillation method . Shale oil is mainly in China , Brazil, Russia and Estonia production . In addition, while many media that the U.S. shale gas and shale oil production ranks first in the world . This statement is also problematic. 2011 China produced about 650,000 tons of shale oil , ranking first in the world .frac sand companies So called "America's shale gas and shale oil production ranks first in the world ," no data to support the foundation . The United States is the largest producer of shale gas , tight oil production is also accompanied by big country , but it is a small country of shale oil production ; China is the largest producer of shale oil , shale gas production is a small country .
