  5月15日,记者从煤层气公司获悉,我国首个中低阶煤煤层气田——保德区块煤层气田累产天然气突破60亿立方米,成为国内首个累计产量突破60亿立方米的中低阶煤煤层气田。

  近年来,煤层气公司在大力发展深层煤岩气开发的同时,全面部署“浅层煤层气保稳产”工作,做精气藏研究、做细气井措施、做好管理提升等工作,有力促进了中低阶煤煤层气产量稳中有升。

  煤层气公司积极探索浅层煤层气提高采收率的方法,针对保德区块局部区域采出程度低、薄煤层动用程度低、部分单井产能未充分释放等关键问题,重点围绕“向弱动、向甜点、向微观、向纵向”4个方面开展挖潜。同时,公司优化方案部署、深化管理变革,通过“一井一策”单井综合分析,量身定制气井“个性化”排采方案,完善气井全生命周期管理卡片,平均修井周期延长30%以上;大力实施重复压裂、补层压裂等措施,进一步提高储层利用效率,整体措施有效率达81%、综合递减率控制在1%以内。公司还充分利用自动化信息平台,实时掌握保德区块生产波动情况,异常井处置效率提升33%。(方亮 张庆丰 李子玲)
