| 摘 要： | 根据王坡井田地质条件及3号煤层储层特征,结合区内地形和交通等条件,分析了适合于王坡井田的煤层气开发方式,并采用数值模拟方法预测了不同方式的煤层气井产量及储层压力和含气量的变化,评价了本区煤层气的开发潜力。结果表明:王坡井田3号煤厚度大,含气量高,渗透性好,具有良好的资源开发前景;丛式井和水平井开发不仅能提高产量,还能有效降低井下瓦斯含量,两种方式相结合将带来巨大的经济效益和广阔的商业前景。

| Abstract: | Based on the Wangpo minefield geological condition and coal No.3 reservoir characteristics, combined with topographic and transportation conditions in the area, analyzed CBM exploitation mode propitious to the minefield. Using numerical simulation predicted CBM production, reservoir pressure and gas content variation under different exploitation modes, and evaluated CBM exploitation potential in the area. The result has shown： the coal No.3 in the minefield has large thickness with high methane content, good permeability, thus favorable exploitation prospect. Using cluster and horizontal wells can not only increase output, but also reduce underground gas content effectively; the combination of the two modes will bring great economic results and extensive business prospects. |
