摘　　要： 随着莫里青断陷油气资源的不断开发,为进一步满足高产、稳产的需要,结合莫里青断陷16口井的实测资料,统计分析了72个Ro测试结果、352个(S1+S2)和TOC测试结果,运用生烃潜力法,并结合莫里青断陷复杂而特殊的构造背景,定性并定量地对莫里青断陷油气的初次运移和二次运移时间进行了探讨。结果表明:莫里青断陷双阳组烃源岩在埋深2 400 m±100 m达到排烃门限,开始初次运移,此时与永吉组沉积时期相对应;二次运移大量进行的时期为永吉组和岔路河组沉积时期。 With continuous development of oil and gas resources in Moliqing fault depression,we have combined with the measured data of 16 wells in Moliqing fault depression to meet the needs of high yield and stable production. In the meantime,we have analyzed the test results of the vitrinite reflectance,including genetic potential and organic carbon contents in this research. Based on hydrocarbon generation potential method and combined with complex and special tectonic setting of Moliqing fault depression,we have discussed the primary migration and secondary migration time of oil and gas in Moliqing fault depression qualitatively and quantitatively.The results show that the source rocks of Shuangyang Formation in Moriqing fault depression have reached the hydrocarbon expulsion threshold at the depth of 2 400 m ± 100 m. It begins with the primary migration,which corresponds to the sedimentary period of Yongji group. The period of the second migration is a period of time for Yongji Formation and Chaluhe Formation.
