摘要

随着全球能源结构转型的加速，深部煤层气作为一种重要的非常规天然气，已成为中国天然气增产的战略接替资源.冀中坳陷作为渤海湾盆地的重要组成部分，其石炭系‒二叠系煤系历经多期构造演化，呈现复杂的地质特征与煤层气富集规律.本文基于钻井、测井及实验测试数据，系统分析了冀中坳陷深部煤层气的地质特征、富集主控因素及成藏模式，并提出了有利勘探区优选方案.研究表明，冀中坳陷深部煤层厚度大（太原组单层最大25 m）、埋深差异大（1 000~5 600 m），煤岩镜质组反射率

总体在0.65%~0.95%之间，显微组分以镜质组为主（46.7%~97.4%），热成熟度受火山烘烤作用影响显著，局部

高达4.6%.煤层含气量（6~18 m³/t）与煤厚、压力系数及保存条件密切相关，深部弱超压环境（压力系数

1.18）及稳定盖层（碳质泥岩突破压力15~29 MPa）对气体富集与保存具有重要作用.研究揭示火山活动引发的异常热流是促进煤层气产气的关键地质因素，二次生烃与构造保存条件的时空配置主导了成藏过程.通过综合评价，文安斜坡中‒内带及大城凸起东北部被划为I类有利区，具备煤层厚度大（6~8 m）、生气强度高（

110 m³/t）、吸附能力强（平均兰氏体积11.39~12.42 m³/t）等优势.研究成果可为冀中坳陷深部煤层气勘探开发提供理论支撑，也为类似残留断陷型盆地煤层气资源评价提供了重要参考.

Abstract

With the acceleration of the global energy stru

cture transformation

deep coalbed methane as an important unconventional natural gas has become a strategic replacement resource for China’s natural gas production increase. As an important part of the Bohai Bay Basin

the Jizhong Depression has undergone multiple tectonic evolutions in its Carboniferous-Permian coal-bearing strata

presenting complex geological characteristics and coalbed methane enrichment patterns. Based on drilling

logging and experimental test data

this paper systematically analyzes the geological characteristics

main controlling factors of enrichment and accumulation models of deep coalbed methane in the Jizhong Depression

and proposes a favorable exploration area selection scheme. The research shows that the deep coal seams in the Jizhong Depression are thick (the maximum single layer of the Taiyuan Formation is 25 meters)

with significant burial depth differences (1 000-5 600 meters)

and the vitrinite reflectance (

) of the coal rocks generally ranges between 0.65% and 0.95%

with vitrinite as the main maceral component (46.7%-97.4%). The thermal maturity is significantly affected by volcanic baking

and the local vitrinite reflectance (Ro) is as high as 4.6%. The gas content of the coal seam (6-18 m³/t) is closely related to the coal thickness

pressure coefficient and preservation conditions. The weak overpressure environment (pressure coefficient

1.15) and stable cap rock (breakthrough pressure of carbonaceous mudstone 15-29 MPa) in the deep part promote gas enrichment. The study reveals that anomalous heat flow triggered by volcanic activity is a key geological factor enhancing coalbed methane generation

and the spatio-temporal configuration of secondary hydrocarbon generation and structural preservation conditions dominates the accumulation process. Through comprehensive evaluation

the middle to outer belt of the Wena Slope and the northeastern part of the Dacheng Uplift are classified as Class I favorable areas

with advantages such as large

coal seam thickness (6-8 meters)

high gas generation intensity (

110 m³/t)

and large Langmuir volume (average 11.39-12.42 m³/t). The research results provide theoretical support for the exploration and development of deep coalbed methane in the Jizhong Depression and offer a reference for the evaluation of coalbed methane in similar residual faulted basins.
