摘要
准南煤田主要含煤地层为侏罗系西山窑组和八道湾组,中低煤阶煤层气资源丰富,勘查程度相对较高,开发条件较好。煤层气赋存具有大倾角、多煤层、厚煤层特点,储层多为低压储层,渗透性低-中等,煤层气吸附性较好,含气量较高。
The main coal-bearing strata in Zhunnan Coalfield are the Jurassic Xishanyao Formation and the Badawan Formation. The middle and low rank coalbed methane resources are abundant with relatively high exploration degree and better development conditions. The Coalbed methane deposits have the characteristics of large inclination, multiple and thick coal seams. The reservoirs mostly have low-pressure with low and medium permeability. The Coalbed methane has good adsorption and high gas content.
