摘要：
To study the genesis and controlling factors of dolomite reservoirs, through the analysis on field outcrop, core and other data, the Cambrian-Ordovician dolomites developed in the north central part of North China Platform are mainly distributed in the Fujunshan Formation, upper part of Mantou Formation, upper part of Maozhuang Formation, middle part of Zhangxia Formation, upper part of Yeli Formation, upper part of Liangjiashan Formation, lower part of Majiagou Formation, upper part of Majiagou Formation and lower part of Fengfeng Formation. The rock types include the microcrystalline dolomite and granular dolomite with protolith structure as well as the micritic dolomite, fine dolomite and medium dolomite without protolith structure. The storage space of the Cambrian-Ordovician dolomite reservoirs include intercrystalline pore, intercrystalline dissolution pore, intracrystalline dissolution pore, intergranular pore, intragranular dissolution pore, intragranular dissolution vug and a small amount of dissolution fractures, dominated by intercrystalline pore and intercrystalline dissolution pore. The Cambrian-Ordovician dolomite is mainly formed in the process of evaporative dolomitization, permeation and dolomitization, burial dolomitization, and tectonic hydrothermal dolomitization. The favorable sedimentary environment, continuous dolomitization and the dissolution in different periods jointly control the formation of dolomite reservoir in the study area. © 2018, Editorial Office of ACTA PETROLEI SINICA.
