贵州省煤层气勘探开发进展及“十四五”开发战略

Progress of coalbed methane exploration and development in Guizhou and the 14^(th) Five-Year Plan development strategy

贵州省煤层气资源丰富,近十年来勘探开发取得重要进展,但当前仍面临若干问题。为了推进煤层气产业发展,梳理了贵州煤层气勘探开发现状及存在问题,并对“十四五”期间煤层气勘探开发战略目标、总体布局、工作部署、工作重点等进行了研究探讨,提出了煤层气产业发展的保障措施与建议。研究结果表明:①工作进展:煤层气勘探开发理论与技术体系已逐步建立,煤层气井产气效果取得了不断突破,六盘水、毕节煤层气开发利用已初具规模;②战略目标:完成16~20个区块煤层气勘探工作,累计提交探明储量800×10^(8)m^(3),年产能8×10^(8)m^(3),年产量4×10^(8)m^(3);③总体布局:以钟山为勘探开发示范区,盘州、织金为重点建产区,带动周边重点勘探开发试验区、后备勘探区的勘探开发工作;④工作重点:分批投放探矿权16个以上,开展毕节、遵义等区块煤层气基础地质调查项目5项,实施煤层气重点勘探开发项目30项,开展煤层气开发地质理论与高效开发技术重大专项研究;⑤保障措施:省级政府加强组织领导,为煤层气勘探开发企业提供政策支持,完善资金投入支持体系建设,推进专业团队建设与人才培养,创新煤层气地质理论与勘探开发技术。结论认为,贵州省煤层气开发潜力巨大、产业化前景广阔,在省级层面引导与政策支持下,依托专业人才培养与技术模式创新,“十四五”期间可迎来贵州地区煤层气产业快速发展的新格局。

In the past ten years,great progress has been achieved in the exploration and development of coal bed methane(CBM)in Guizhou district due to its abundant CBM resources.However,there are still some problems.In order to promote the development of CBM industry,this paper reviews the status and problems of CBM exploration and development in Guizhou,and discusses and studies the strategic objective,overall layout,work deployment and work focus of CBM exploration and development during the 14^(th) Five-Year Plan.In addition,measures and suggestions on guaranteeing the development of CBM industry are put forward.And the following research results are obtained.First,work progress:the theories and technologies for CBM exploration and development have been established gradually,breakthroughs have been made continuously in the gas production effect of CBM wells,and CBM development and utilization takes shape in Liupanshui and Bijie.Second,strategic objective:complete CBM exploration in 16-20 blocks,submit cumulative proved reserves of 800×10^(8)m^(3)and realize yearly productivity of 8×10^(8)m^(3)and yearly production of 4×10^(8)m^(3).Third,overall layout:take Zhongshan as the exploration and development demonstration area and Panzhou and Zhijin as the key productivity construction areas to drive the exploration and development in peripheral key exploration and development test areas and reserve exploration areas.Fourth,work focus:put more than 16 exploration rights in place in batches,carry out 5 CBM basic geological survey projects in Bijie and Zunyi Blocks,implement 30 key CBM exploration and development projects,and conduct major researches on CBM development geological theories and efficient development technologies.Fifth,guarantee measures:provincial governments shall strengthen organization and leadership,provide CBM exploration and development enterprises with policy support,improve the construction of capital investment support system,promote the construction of professional teams and the training of talents,and innovate CBM geological theories and exploration&development technologies.In conclusion,the potential of CBM development is great and its industrialization prospect is promising in Guizhou.Under the guidance and policy support at the provincial level,combined with the training of professional talents and the innovation of technological model,the CBM industry in Guizhou will usher a new pattern of rapid development during the 14^(th) Five-Year Plan.
