摘要

查明不同构造部位煤储层物性及产气差异，可为煤层气合层开发提供重要依据。以五里堠井田20口煤层气合采井为例，基于目标开发层位（3号+4号煤层和15号煤层）的煤层底板构造形态和构造曲率，划分了构造组合类型。结合已有勘探资料，系统对比了不同构造部位煤储层的显微组分、吸附特性、煤体结构、含气特性与渗透率等关键物性参数差异，并分析了典型合采井的产气特征（排采曲线特征）。结果表明：①研究区煤储层构造组合可划分为7种类型：背斜-背斜型、背斜-平缓型、向斜-向斜型、向斜-平缓型、平缓-平缓型、平缓-背斜型和平缓-向斜型。②查明了研究区目标煤层（3号+4号煤层和15号煤层）在不同构造位置的显微组分、吸附特性、煤体结构、含气量和渗透率的物性差异。储层变形程度与灰分含量、Langmuir体积和煤体结构特征均有较强相关性。3号+4号煤层和15号煤层的构造曲率差值与含气量差值呈负相关，含气量变化范围较小；而与渗透率差值呈正相关，渗透率变化显著。不同构造组合类型的煤层含气量差值（单位：m

/t）依次为：平缓-背斜型（1.55）

平缓-向斜型（1.42）

背斜-平缓型（1.41）

平缓-平缓型（1.32）

向斜-平缓型（1.06）

向斜-向斜型（0.77）

背斜-背斜型（0.58）；渗透率差值（单位：10⁻³ μm²）

依次为：背斜-平缓型（0.24）

向斜-平缓型（0.21）

平缓-向斜型（0.19）=背斜-背斜型（0.19）

向斜-向斜型（0.17）

平缓-平缓型（0.16）

平缓-背斜型（0.11）。③对比不同构造部位合采井产气特征：背斜-背斜型、背斜-平缓型产气效果较好，产气峰值普遍超过1 000 m

/d；平缓-平缓型、平缓-背斜型和平缓-向斜型产气波动性较大，峰值介于200~1 200 m

/d；向斜-向斜型、向斜-平缓型产气表现较差，峰值仅约200~500 m

/d。

Abstract

Identifying the differences in physical properties and gas production of coal reservoirs at different structural locations provides an important basis for the co-development of coalbed methane (CBM). Taking 20 CBM co-production wells in the Wulihou mine field as an example

the structural combination types of reservoirs were classified based on seam floor configuration and structural curvature of the target development layers (No.3 + No.4 coal seams and No.15 coal seam). Combined with existing exploration data

the study compared key physical parameters of reservoirs at different structural locations

such as maceral components

adsorption characteristics

coal structure

gas-bearing characteristics

and permeability

and analyzed the drainage and production curve characteristics of typical co-production wells. The results indicated that: (1) The structural combination of coal reservoirs in the study area could be classified into seven types: anticline-anticline

anticline-gentle

syncline-syncline

syncline-gentle

gentle-gentle

gentle-anticline

and gentle-syncline. (2) The differences in maceral components

adsorption characteristics

coal structure

gas-bearing characteristics

and permeability were identified between the No.3 + No.4 coal seams and the No.15 coal seam at different structural locations. The degree of reservoir deformation was strongly correlated with ash content

Langmuir volume

and coal structure. The difference in structural curvature between the No.3 + No.4 and No.15 coal seams was negatively correlated with the difference in gas content

with a relatively small range of gas content variation

but was positively correlated with the diffe

rence in permeability

which changed significantly. The differences in gas content (unit: m³/t) across different structural combination types followed the order: gentle-anticline (1.55)

gentle-syncline (1.42)

anticline-gentle (1.41)

gentle-gentle (1.32)

syncline-gentle (1.06)

syncline-syncline (0.77)

anticline-anticline (0.58). The differences in permeability (unit: 10

-3

μm

) followed the order: anticline-gentle (0.24)

syncline-gentle (0.21)

gentle-syncline (0.19) = anticline-anticline (0.19)

syncline-syncline (0.17)

gentle-gentle (0.16)

gentle-anticline (0.11). (3) Comparisons of gas production characteristics of co-production wells at different structural locations showed that the anticline-anticline and anticline-gentle types had better gas output

with peak values generally exceeding 1 000 m

/d. The gentle-gentle

gentle-anticline

and gentle-syncline types showed significant production fluctuations

with peak values between 200 and 1 200 m

/d. The syncline-syncline and syncline-gentle types showed poorer gas production performance

with peak values only about 200-500 m

/d.
