The China National Petroleum CBM Laboratory started the national metrological certification in 1994 and successfully passed the 4-year qualification review. At present, the laboratory has more than 10 sets of international advanced equipment and equipment, forming a complete laboratory testing technology series. In particular, it is at the leading level both at home and abroad in terms of coal bed methane accumulation simulation, coal bed methane rapid desorption and coal thermal deformation simulation. On the basis of a large number of test and analysis tests, this laboratory combines theoretical research with the practice of coalbed methane exploration, and proposes six geological theories of coalbed methane accumulation in China, forming CBM resources evaluation, reserves evaluation, and other Chinese coalbed methane Exploration and development of eight key technologies.
These technical equipment and exploration theory have played a major role in the exploration of coalbed methane resources in China, providing raw data for the exploration of CBM reserves of 46 billion cubic meters, control forecast of 200 billion cubic meters, and development of the Qinshui CBM field. The parameters are based on good technical support and the role of the General Staff for the exploration and development of CNBM and even China's CBM.
Up to now, this laboratory has accumulatively obtained more than 30 research results, published works such as “China Coalbed Methane Geologyâ€, published 150 papers on CBM in domestic and foreign publications, won the second prize for national scientific and technological progress, and achieved scientific and technological progress in Beijing. First prize and more than 20 items.
Recently, researchers are developing key technologies for CBM development, such as large-path fast rope coring tools and injection/pressure drop test methods, coal seam stress and permeability testers, multi-branch horizontal well underbalanced drilling equipment, and so on. The branch CBM laboratory has been built into a world-class comprehensive laboratory that serves the most comprehensive experimental test projects for CBM exploration and development at home and abroad.
On the previous day, two instruments, the China Petroleum CBM Laboratory Quick Desorption Apparatus and the Coal Thermal Abnormal Thermal Simulation Device, were awarded 2007 2007 Utility Model Patent Certificates issued by two countries. The patent numbers were 279,411 and 279,401 respectively. This is another national patent obtained by the laboratory following the acquisition of a national invention patent (Patent No. 200410074732.1) and a utility model patent (Patent No. 200420093572.0) for a coalbed methane accumulation simulation test device in 2005. This indicates that CNPC has built the largest integrated laboratory CBM exploration and development laboratory in China with the most comprehensive analysis and testing programs.
