松辽盆地巴彦查干地区油源断裂向葡萄花油层输导油气时空展布特征
Temporal and spatial distribution characteristics of source faults trans-porting oil and gas to Putaohua reservoir in Bayanchagan area of Songliao Basin
摘要
Abstract
In order to clarify the law of oil and gas distribution of Putaohua reservoir in Bayanchagan area of Songliao Basin,based on the study of source faults transport location of Putaohua reservoir in Bayanchagan area,distribution area of source rock hydrocarbon expulsion in Qing-1 Member(K2 qn1)and source faults transport peri-od,source rock hydrocarbon expulsion period of Qing-1 Member and oil and gas charging period,temporal and spa-tial distribution characteristics of source faults transporting oil and gas are obtained,and the relationship with oil and gas distribution is analyzed.The results show that,spatial distribution of source faults transporting oil and gas to Putaohua reservoir in Bayanchagan area is mainly in central area,followed by southern area.At present,oil and gas of Putaohua reservoir are distributed in spatial distribution area of source faults transporting oil and gas.Source faults transporting oil and gas occurs mainly at end period of Mingshui Formation deposition,and is relatively short.During this period,oil and gas supply of Qing-1 Member source rock is limited,resulting in oil and gas mainly dis-tributed in eastern high part and relatively less in low part of western structure.The research provides basis for sub-sequent oil and gas exploration in Bayanchagan area.关键词
