郑庄区块煤层气储层特征分析

Characteristics Analysis of Coalbed Methane Reservoir in Zhengzhuang Block

郑庄区块是沁水盆地主要的煤层气勘探开发区块,该区块煤层厚度大、展布稳定、含气量高、储层压力大,为煤层气的勘探开发提供了较好的物质基础。通过对郑庄区块已施工的煤层气参数井和生产井的煤层厚度、孔渗、储层压力、含气量统计分析,梳理了区内煤层展布规律以及煤层气储层的关键控制参数,以期为该区煤层气的深入高效开发提供参考。

Zhengzhuang Block is a key exploration and development block of coalbed methane in the Qinshui Basin.The Block is characterized by thick coal seams,stable distribution,high gas content and high reservoir pressure,which provides a solid material basis for coalbed methane exploration and development.Based on the statistical analysis of coal seam thickness,porosity and permeability,reservoir pressure and gas content of the coalbed methane parameter wells and production wells constructed in Zhengzhuang block,the distribution patterns of coal seams in the Block are comprehensively examined and the key controlling parameters of coalbed methane reservoirs are identified,aiming to provide a reference for the in-depth and efficient development of coalbed methane in this area.
