Abstract：Developing green coal chemical industry is the inevitable choice of implementing green China Coal Group. The concept of green coal chemical is advanced, but in actual operation there are still many problems, mainly is the design issues, ideas and technical problems and the lack of evaluation system. So establishing and perfecting evaluation system is the premise and key to promote the implementation and de-velopment of green coal chemical industry. At the same time, we should enhancechemical management and field operating workers to understand and agree with green chemical, strengthen the research in the green chemical technology, further deepen the key technology re- search and development, establish and improve the green coal chemical industry standards. Green coal chemical industry is the need of sustain-able development of China Coal Group,is a system engineering, invol-ving many majors and aspects. The complexity of the green chemical makes many related problems remain to be further studied, more need for deeper research of coal chemical industry professionals.

Evaluation method of energy-saving special investment project of oil and gas field LAI Xian-lin,GE Yong-guang （Xinjiang oilfield company engineering consulting center, karamay 834000, China） Abstract：According to problem of difficulties in determining the evaluation boundary, evaluating the energy conservation and comparing the evaluation index in the energy saving investment project post-eval- uation work,we put forward a viewpoint that,to determine the project boundaries by the funds, to calculate the energy by the method of test report combined with production statistics, and to make the coincidence rate of the million Yuan investment and energy saving standard coal quantity as the main evaluation indicators. It can effectively soNe the difficulty of recent work in the post-evaluation energy saving invest- ment project. Key words ： oil and gas field; energy-saving ;investment; post-eval- uation
