摘要:
鄂尔多斯盆地在大牛地气田2 800 m以深的中煤阶深层煤层气勘探开发中取得了重大突破,其中阳煤1HF井单井最高日产气量超10.4×104 m3,稳产时间已超过1年,平均稳产气量6.3×104 m3/d,累计产气量超2 300.0×104 m3。通过对该区深部中煤阶煤及煤层气地质特征的分析,提出了“区带优选、层段控制、规模压裂、精细排采”建产思路并实践应用。根据含气量、煤层厚度与特征、顶板条件和热演化程度对榆阳目标区进行了优选评价,研究表明:研究区以原生结构半亮煤为主,含气量主要分布在16.50 ~ 26.00 m3/t,游离气占总含气量的20 % ~ 25 %,平均孔隙度为4.68 %,平均渗透率为0.24×10-3 μm2,割理/裂隙发育,部分被方解石充填。光亮煤和半亮煤的总厚度大及高含气量是高产的基础,大排量和大规模改造是高产的关键。规模压裂时,要基于“饱和加砂、控近扩远、有效支撑”的工作思路,以“多簇密切割+大排量+高强度加砂”为有效技术手段。合理控制降压速率是深层煤层气井稳产、高产的关键,采用“控砂不控粉”排采理念,在排液和快速上产阶段采用光套管生产,在自喷生产阶段下入生产管柱采用控压连续、稳定排采,阳煤1HF井的控压生产实践已证实这些措施效果良好。
