%X The estimation of fault sealing is a crucial issue in studying petroleum migration and accumulation in sedimentary basins. In 1966 Smith has proposed the theoretical model of Fault Sealing, since then, many scholars have done a lot of work in estimating and predicting the fault seal in clastic strata, and have made great progress of the study during last 10 years.The paper analyses deeply on the lateral fault seal by clay smear on the basis of the precensors studies. Using the Shale Gouge Ratio by Yielding etc in 1997 and its quantitative relationship with the fault seal across the faulted zone, we apply it to several important faults in the southwest of Jianghan Basin, calculate their Shale Gouge Ratio values and analyse the relationship between these Shale Gouge Ratio values and the fault seal across the faulted zone, furthermore, we study the fault seal with the oil migration and accumulation. As a result, it can be proved that Shale Gouge Ratio is an efficient index in studying the lateral fault seal.
