| 摘 要： | 华北地下古生界储集层主要存在四种类型:古岩溶型、同重结晶作用有关的白云岩型、同构造作用有关的裂缝型和粒屑灰岩型。其中古岩溶型最为有利,其次为白云岩型和构造裂缝型,粒屑灰岩型则相对较差。在纵向地层中,认为最有利的储层分布在奥陶系碳酸盐岩古岩溶中,其次在上寒武统白云岩中。表生期岩溶作用是风化壳储层形成的最根本原因,孔隙型白云岩储层大多受岩性控制。太参3井及其以西、和鄂尔多斯西南缘的陇县、礼泉地区白云岩储层与古岩溶型储集层相互组合比较好,是有利储集层发育区。

| Abstract: | The Lower Paleozoic carbonate reservoirs may be divided into four types such as ancient karst reservoir, recrystallization-related dolomite reservoir, tectonism-related crack reservoir and calcirudite reservoir. The ancient karst reservoir is the most favorable one, followed by dolomite reservoir and crack reservoir as well as calcirudite reservoir. The ancient karst reservoir occurs in the Ordovician and Upper Cambrian dolomitite. The favorable reservoirs are distributed over Taican 3 well and to the west, Longxian and Liquan on the southwestern margin of Ordos. |
