摘要
The growth index of a fault is related not only to its activity rate but also to the deposition rate, especially in seriously truncated area, the growth index is serious distorted. But this situation has been neglected for a long time. Based on growth index and fault activity rate, the activity intensity of Linnan fault is studied, and it is so considered that the conclusion of latter is right. The speed of activity of a fault can be directly attained from the duration of sedimentation and reflects quantitatively the activity intensity of the fault, thus the terminology of the growth index of fault is practically meaningless. Fault activity was strong during Dongying time, and the buried depth of stratum is shallow, so fault sealing is worse, hydrocarbons migrated to Qianguantun and Qudi areas. This is important to hydrocarbon accumulation. Fault activity intensity was big during Minghuazhen time, which determined the vertical hydrocarbon distribution.
