摘要： 综合利用大量岩心、薄片，钻井、测井、地震等资料，对古岩溶识别标志进行了分析；运用印模法、残差厚度法和不整合类型相结合，恢复了奥陶系岩溶古地貌，对古地貌单元进行划分并分析其对储集层的控制作用。在岩溶高地、岩溶缓坡、岩溶陡坡和岩溶盆地4个二级地貌单元，分别定量划分出残丘、台地、阶坪和沟谷4个三级地貌单元。岩溶缓坡区残丘、台地、沟谷末端、沟谷两侧及岩溶陡坡区台地和阶坪是岩溶储集层发育的有利区。

Abstract: Using the data of core, thin section, drilling, logging and seismic profile, the mark of palaeokarst identification is analyzed; the Ordovician karst palaeogeomorphology is restored with impression method and residual thickness method combined with unconformity structures; karst paleogeomorphic units are classified and their controlling effects on reservoirs are analyzed. In the 4 secondary paleogeomorphic units such as karst highland, karst gentle?slope, karst steep?slope and karst basin, 4 tertiary paleogeomorphic units (monadnock, tableland, level terrace and clough) are further classified quantitatively. The favorable areas for karst reservoir development are monadnocks and tablelands in the karst gentle?slope, the ends and flanks of the clough, and the tablelands and level terraces in the karst steep?slope
