海拉尔-塔木察格盆地塔南凹陷洼槽区油气成藏模式特征研究

he paper researched the characteristics of hydrocarbon accumulation types of sags, Tanan depression in Hailer-Tamuchage basin. Then the basic characteristics and special laws of oil and gas accumulation in sags of terrestrial fault basin have been summarized in the paper. The results show that the characteristics of hydrocarbon accumulation types of sags are: depression source leaching under the reverse fault block model, lying within the heart source model etching lithologic traps, grease, depression slope ( wing ) source on leaching - etching patterns and fault seal, grease source outside the fault depression slope transport type Reverse fault block model of oil accumulation.
