摘要
华北地区下古生界主要为一套浅海台地碳酸盐岩。其中奥陶系中统及寒武系下统是该区储集岩发育的主要层段。储集岩以溶蚀孔隙和裂隙为主,加里东期和燕山-喜山期的岩溶作用及断裂作用是储集岩形成的主要地质因素。
Carbonate reservoir rocks of Lower Paleozoic in North China are mainly developedin Middle Ordovician and Lower Cambrian,and are characterized by solution pores andfissures.Karstification and faulting in Caledonian and Yenshan-Himalayan periodsresulted in a reservoir zone(200m thick)below erosion surface with dolomite as the prin-cipal reservoir rocks.
