摘要

为查明红果区块煤层气勘探潜力,利用煤炭钻孔及煤层气井资料,从地质背景、煤岩煤质、储层物性、含气性和保存条件等入手,系统分析了煤层气富集的基本地质条件,初步评价了煤层气的资源潜力,并对有利富气区进行综合评价与优选。结果认为：红果区块煤储层具有埋深适中（500~1 200 m）、累厚大（10.3~25.8 m）、热演化程度中等（0.9 %~2.0 %）、含气量高（10.8~26.3 m ³/t）等特征,煤层气成藏地质条件优越。综合评价煤层气有利区面积260 km ²,资源量422×10 ⁸m ³,其中I₁类有利区位于向斜东部,演化程度高、割理裂隙发育、压力系数高、保存条件优越,是下一步勘探评价的重点目标区。

Abstract

In order to evaluate the CBM exploration potential of Hongguo Block, the basic geological conditions for the enrichment of CBM reservoirs were analyzed from the aspects such as stratigraphic distribution, coal quality, physical characteristics, gas-bearing capacity and preservation conditions by the data of coal drilling and CBM wells. And then the resource potential of CBM was preliminarily accessed. Finally, the favorable gas-rich areas were further optimized. Results show that coal bed in Hongguo Block has the characteristics of moderate burial depth（500~1 200 m）, large accumulated thickness（10.3~25.8 m）, moderate thermal maturity（0.9 %~2.0 %） and high gas content（10.8~26.3 m ³/t）, with superior geological conditions of CBM accumulation. By the comprehensive evaluation, the favorable CBM area is about 260 km ² and the amount of resource is about 422×10 ⁸ m ³. The most favorable area type I₁ is located in the east of Panguan syncline, with high thermal evolution degree, developed cleavage and fissure, high pressure coefficient, and superior preservation conditions, which is the primary target area for the next CBM exploration.

Key words： Hongguo Block; CBM; resource assessment; exploration potential; Panguan syncline
