摘　　要：研究煤层气储层结构的特性,基于不规则三角网(TIN)生成算法提出一种新的煤层气储层三维可视化方案。该方案将勘探获得的采样点地理数据经过变换,使之成为适合Java3D坐标系的空间坐标数据,并根据各采样点的解释分层,构建煤层气储层的三维模型。可以在勘探现场根据采集得到的数据即时生成该区域煤层气储层的三维模型,而且可以在J2EE平台上发布,实现资源的网络共享。应用结果表明,该方案能根据勘探采集的即时数据,较为真实地描述煤层气储层的三维结构。We studied the characteristics of coal-bed methane （CBM） reservoir structure, and proposed a new three-dimensional visualisation scheme for CBM reservoir based on the triangulated irregular networks （TIN） generation algorithm. In the scheme, the geographic data of sampling points acquired from exploration were transformed to the spatial coordinate data being compatible with Java3D coordinate system. A three-dimensional model of CBM reservoir was built based on different interpretation layers of sampling points. In the exploration site it was able to instantly generate the three-dimensional model of CBM reservoir in that area according to data collected, which could be published on J2EE platform as well to realise source network sharing. Application result showed that the proposed program can describe the three-dimensional structure of CBM reservoirs more truly based on the instant date collected in exploration.
