In order to study the distribution rule of hydrocarbon in fault-sand configuration traps, determines the favorable location for transporting hydrocarbon by studying the mechanism of fault-sand configuration transporting hydrocarbon. Based on the overlapping distribution area of favorable transporting location and favorable reservoir hydrocarbon sand body, determines the favorable location for transporting and accumulating hydrocarbon in fault-sand configuration traps. Based on the above study, establishes a research method for predicting the advantageous location for hydrocarbon migration and accumulation in fault-sand configuration traps, and it is applied to predict the advantageous location of hydrocarbon migration and accumulation in the fault-sand configuration trap of the T2 oil formation of F1 fault in TN oilfield. The results show that, in T2 formation, the favorable parts of F1 fault in TN oilfield mainly distribute in the south-central and north-central survey lines, which is conducive to the accumulation and distribution of hydrocarbon generated by underlying source rocks in T2 formation, which is consistent with the hydrocarbon found in T2 formation near F1 fault in TN oilfield. It shows that the method is feasible to predict the favorable position of hydrocarbon transportation in the fault-sand configuration.
