The Rise of Non Conventional Energy Prompted the Reunderstanding and Division of Oil and Gas Migration in the Petroleum Industry

In recent years, with the development of coal bed methane, especially large-scale success shale oil and gas exploitation, People will not only in sedimentary basin energy re classified as conventional energy and non conventional energy, And the non conventional energy referred to an important aspect and a situation of tripartite confrontation of the conventional energy sources, new energy, In this paper, in the identity of non conventional energy in the future as a kind of new energy type, Analysis is made on the global and China's major non conventional energy, resources potential, exploration and exploitation of species status, Foundation and face geological theories and engineering problems on, Emphasis on non conventional energy and conventional energy relationship, Both belong to the Petroleum industry. Is called the non conventional energy, is compared with the conventional energy. Because, whether conventional or non conventional sources of energy, Basically are generated and preserved in the sedimentary basin, or that there is a close relationship with sedimentary basin. Coal bed methane, shale gas, oil sands, oil shale, tight oil and gas, it is called the non conventional energy. Compared with the conventional energy sources -- coal, oil, and gas. Obviously, there are many similarities between them. That is, all belong to the fossil energy, To form (coal) containing oil and gas basin. The formation, not only distribution and evolution of the basin development, And form, and conventional energy accumulation are closely linked, not separate. It can be said that most of the non conventional energy product belongs to the oil and gas in different periods, the same kind of energy at different stages, Research thinks, migration to bridge non conventional energy and conventional energy sources of oil and gas, Unconventional oil and gas is the inheritance and development of conventional oil and gas, Unconventional oil and gas is the extension and expansion of conventional oil and gas denotation, connotation .
