Abstract: The sinian dolomite in Weiyuan is an old reservoir rock of complex structure. A detailed description of its structural features and distribution pattern is given with the application of analytical study of reservoir evolution and pore structures. The mechanism of formation of pores is touched upon at some length. Reservoir study and its application in regulation of production is dealt with in the concluding part.

摘要： 威远震旦系白云岩层是年代老、结构复杂的储集层。本文应用储层演化分析和空隙结构分析相结合的方法,较详细地论述了储层的结构特征和分布规律,提出了储层结构模式,文中也探讨了空隙形成的机理。最后部分是关于储层研究在开发调整中的应用。
