全国政协副主席王文元５月份在接受中国煤炭报记者采访时说，煤层气发展缓慢的原因，就是一些人只看到煤层气开发投入高，难度大，单井产量低、投资回报长等弱点，没能考虑它的环境效益和社会效益。只有从国家整体利益出发，综合算帐，才能得出宏观的结论，拿出正确的措施。 王 Wang Wenyuan, vice chairman of the Chinese People’s Political Consultative Conference, told China Coal News in May that the slow development of coalbed methane is because some people see only weaknesses such as high investment in coalbed methane development, high difficulty, low single well output and long investment returns, Failed to consider its environmental benefits and social benefits. Only from the overall national interest, comprehensive accounts, can come to a macro conclusion, come up with the right measures. king
