Abstract
According to hydrocarbon source,fault system features,reservoir facies and sand body growth property,the major factors of controlling reservoir formation in Fulongquan-Gujiadian anticlinal belt are analyzed;the reservoir formation law is summarized and it is pointed that the hydrocarbon potential of the northern high of Fulongquan structure is relatively fair.Rift formaton and depression formation belong to upper and lower two sets of fault systems respectively and there is no any big reverse faulf extending to surface.The rift formation mainly shows three retreating-style contemporaneous faults,which controlled the development of rift strata;the depression formation shows a lot of small faults,which plays destruction and rejustment roles in primary oil and gas reservoirs.There are a few faults in the top of Denlouku Formation in rift-depression transformation stage.The preservation conditions of oil and gas in mid-depth strata (Yuancheng Formation and Denlouku Formation) are good,because the upper faults aren′t interconnected with the lower ones.In light of the data on gas showings in drilling,it is considered that the shallow gas reservoirs in the depression formation area are the secondary remnant ones,and the difference of gas showing in various wells and the gas-bearing area and gas column height of the gas reservoir are mainly controlled by faults and facies.A suggestion on attaching impor-tance to the oil and gas exploration in mid-depth strata in the northern high of Fulongquan structure is proposed according to the results of research.关键词
