摘要： 通过对维马克2号含气构造的详细剖析,认为本构造的主要勘探目的层为低孔低渗-特低孔特低渗储集层，天然气富集于志留系下砂岩段中,以湿气为主。气源既有晚期干酪根裂解气的贡献，也有原油裂解气的贡献,具同源不同期的混合特征。存在两期成藏,以喜马拉雅运动期为主;成藏主要受控于有效的储盖组合,相对均质的储集层、裂缝发育的有效部位及背斜两侧的断裂等因素。

Abstract: The in-depth analysis of W eimark-2 gas-bearing structure shows that the main targets for exploration should be the reservoir with low porosity-low permeability and extremely low porosity-extremely low permeability, and gas enriches in lower sand section of Silurian, dominated by wet gas. The gas supply is both from late kerogen pyrolysis gas and crude cracked gas, with mixture feature of the same source and different stages. There exist two stages of petroleum accumulation principally formed in period of Himalayan movement. The efctive reservoir- cap assemblage, relatively homogeneous reservoir rocks, developed fractures and locations as well as faults in two sides of the anticline are the main controlling factors for forming reservoirs.
