China Gas Information
With the continuous development of China's economy, the energy requirements are growing larger. Coalbed methane as a clean and efficient gas energy, and natural gas calorific value of the quite, effective and scientific development coalbed methane gas supplies can be added, also can reduce coal gas explosion safe hidden trouble, and ease of atmospheric greenhouse effect.
According to the investigation, coalbed methane resources in China in 36.8 trillion cubic meters or so geological, ranked third in the world. Compared with the rich content, the coalbed methane proven rate is low. In recent years, the country has issued corresponding policy, the exploitation of coal-bed methane present a rapid development momentum.
Because the coal and CBM of two resources were born in the same space close underground coal and CBM, overlapping mining right problem once restricted the rational development of coalbed methane and efficient use. Shanxi lvliang three into block is China coal mine overlap in CBM right of one of the worst hit areas, overlap rate is 77%.
In the three areas held recently in coal &cbm cooperation pattern conference, the ministry of land and resources exploration company in oil and gas YangYongGang department chief said, to coordinate two industry development, department of land and resources to resolve overlapping problems as a breakthrough ore rights, and actively construct promote development mechanism of coalbed methane.
In guarantee coal enterprise based on the development of coalbed methane development, promote, five years in the coal production area, will be to the coal enterprise integrated CBM development; In coal production backup area, actively encourage coal and CBM exploration to both the enterprise from the cloth Wells to gas control for all-round cooperation, not only ensure CBM resources is not wasted, and ensure the safety production in coal enterprise, and subsequent development in coal CBM docking, make resources to maximize use; In addition to encourage coalbed methane in several years in coal mining area not development, reduce the coal gas content, the prevention of coal mine drop for low gas coal mine, the construction of high yield of coal to build the foundation.
It is reported, China 2010 an annual capacity of 1.5 billion cubic meters of coalbed methane (CBM), 90% from shanxi review made by, shanxi HanCheng, etc. Experts are expected to 1025, "" period, Chinese CBM output will reach 8 billion to 12 billion cubic meters. Oil HanCheng branch manager of coalbed methane HanJun introduces, at present HanCheng branch in about 110000 cubic meters per CBM, by the end of this year, daily output will reach 60 to 800000 cubic meters.
YangYongGang points out, CBM development scale, because be particular about the large investment and high, therefore, the exploration risk investment return period is longer. China got the right of mine enterprise altogether more than 20, located in 10 DuoGe provinces, but after DuoNian exploration, only 4, 5 home in qinshui basin and ordos basin enterprise get considerable production, achieve the large scale production. As a sunrise industry, CBM development need the support of the community. The state encourages enterprises have been CBM development the attitude of mining enterprises, 0.2 yuan each party to the subsidies.
Shanxi beauty jin energy group jin source chief engineer XieShiMing coal mine coal mining proposal, coalbed methane from cooperation between enterprise and the development of industry, the cooperation between relevant national authorities set up the exploration design to construction, development of the whole process of the uniform standard, in order to form standard .
