RELATION OF MULTICYCLES TO OIL AND NATURAL GAS IN THE ORDOS BASIN

With history and construction analysis,Prof.Huang Jiqing and other geologists founded "multicycle tectonic movement theory",after long-term research on Chinese earth structure.This theory summarized the basic characteristics of Chinese earth structure,developed the multicycle theory,enriched the theory and research method of Chinese earth structure,and made great contribution in directing national oil and gas prospection.On the occasion of Prof.Huang Jiqing's 100th birthday,the author reviews the oil and gas achievements acquired under the multicycle theory and the further analysis on oil-gas geologic condition of the basin,generation and distribution of oil-gas,and the oil-gas exploration decision during the 50 years' oil-gas exploration in the Ordos Basin,expressing honor and cherish memory for the older generation of geologists.
