Abstract: In order to clarify the characteristic of the Cambrian carbonate paleo-ocean environment, to reveal the potential contact of diagenetic fluid and karstification, and predict favorable reservoir development zone, based on the measured carbonate rock outcrop and the system samples, using the trace elements, strontium, carbon and oxygen isotopes and casting thin section data, geochemistry and petrology method, discuss the carbonate paleo-ocean environment and the geological significance. The results show that Qingxudong Formation-Loushanguan Formation of the Cambrian as a whole for the Marine environment in the Dianqianbei depression, the ancient ocean temperature between 12.82℃~32.84℃, subject to warm or hot subtropical climate. Sea level has a main shock downward trend, there are 8 periods of sea level change cycle, development of the corresponding lithofacies combination, and isotope evolution curve can be taken as the basis of stratigraphic classification. Trace element geochemical characteristics confirmed the Loushanguan Formation karstification relative development, diagenetic fluid mixed with strong oxidizing atmosphere water at low temperature, favorable reservoir are mainly distributed in the sea level falling high part of the cycle.
